Chlorine Dioxide Generator

What is Chlorine Dioxide?

It is a yellowish green gas with high solubility in water and is a very powerful oxidizing chemical. It is highly unstable and hence cannot be stored or transported in bulk. Above certain concentration in air it is explosive and hence needs to be generated at site with due precautions.

Chlorine Dioxide – What you can't say from it's name. All water treatment starts with water disinfection. IONIC realised disinfecting water properly is as important as treating water and is offering a unique and cost effective solution for water disinfection.

We have developed fully automatic Chlorine Dioxide generators for water disinfection. CLO2 is 2.5 times more powerful than conventional Chlorine.

Salient Features of Chlorine Di Oxide :

There are numerous advantages of chlorine dioxide over disinfectants, notably chlorine, including:

Chlorine dioxide (ClO2) has a higher disinfection potential than chlorine and is 2.5 times more powerful than chlorine.

No pH dependence – Chlorine dioxide is an effective disinfectant, even at high pH levels where chlorine loses much of its disinfection potential.

No THM formation – Unlike chlorine, chlorine dioxide does not combine with humic or fulvic acids in surface (river) water to form trihalomethanes, suspected carcinogens.

No combination with ammonia – Chlorine dioxide does not combine with ammonia in water, like chlorine, requiring smaller doses to achieve disinfection.

No chlorophenol formation - Chlorine combines with phenols to form chlorophenols, causing taste and odor problems. Chlorine dioxide destroys phenols, eliminating many taste and odor problems.

Oxidization of iron and manganese - Chlorine dioxide rapidly oxidizes soluble iron and manganese to an insoluble state for flocculation and filtration. Chlorine alone takes days to oxide manganese, and cannot oxidize chelated iron.

Oxidizes sulfides without high pH - Sulfide oxidation using chlorine requires high pH to prevent formation of colloidal sulfur, which can plug up equipment. Chlorine dioxide may be used over a broad pH range (5-9) without colloidal sulfur formation.

No loss due to storage – Chlorine concentration in a tank of 12.5% sodium hypochlorite solution is subject to varying decay rates based on ambient conditions. Sodium chlorite and hydrochloric acid may be stored for more than a year without significant decay.

There are many methods to produce ClO2. Most other ClO2 systems mix chlorine gas and sodium Chlorite or they use acid mixed with Sodium Hypochlorite to release chlorine gas and sodium chlorite.

Method of Generation of proposed system :-

The system is designed to produce ClO2 based on acid-chlorite process. This process activates sodium chlorite with hydrochloric acid to generate chlorine Dioxide using the reaction.

5NaClO2 + 4 HCl = 4 ClO2 + 5 NaCl + 2 H2O

The generators are available in 2 versions. Smaller capacity models use dilute 9% HCl and 7.5 % NaClO2 and the larger models use concentrated chemical of 32% HCl & 25 % NaClO2. Dilution Water is added to keep the concentration in the reactor low. The Chlorine Di Oxide solution will have 2% concentration.

Chlorine Dioxide is now recognized one of the safest, most effective ideal biocides and sterilizing agent available today. As a result it is widely used in both large and small scale industrial applications where a potent but environment friendly biocide is required. Many of its uses and applications are US EPA, WHO, FDA, UK and EU government approved: and highly recommended by many researchers and research establishments throughout the word.

Lamella Inclined Plate Clarifier

Ionic Lamella plate clarifier configuration ensures laminar flow conditions, which results in hydraulic uniformity and high effluent quality. It permits great reduction in the space needed for clarification equipment and allows the compact equipment to be located indoors if desired, or to be easily relocated at a later date. It also makes point-source treatment not only feasible, but logical for many applications. The Lamella Clarifier system consists of a series of inclined overlapping plates, which are arranged to form separate sedimentation chambers or cells between each pair of adjacent plates. The overlapping additive projected area of the plates is a factor of increased surface settling which is proportional to the number of plates used.

KEY ADVANTAGES OF LAMELLA CLARIFIER SYSTEM

• No moving parts, thereby minimizing maintenance.
• Time required to stabilize the Lamella Clarifier system after start up is only approximately 20 minutes.
• Continuous operation possible for any length of time without shutdown
• Sludge thickener zone having four sloped hopper bottoms replaces the extra thickener

Solids Contact Clarifier

Solids contact Clarifier is a well-established solid liquid clarification process for effective and efficient removal of suspended solids and other physical contaminants from wastewater. It is a high rate clarifier, which, in minimum time and space and using a minimum of chemicals, produces an effluent of highest quality. It is principally used for coagulation, flocculation and clarification of water and waste water containing suspended solids, colour and organic impurities

Coagulants such as ferrous sulphate, lime and polymer are added for effective precipitation. The solids contact clarifier water and waste water treatment solution is designed to ingeniously combine flash mixing followed by slow speed agitation and settling in one central zone whereby reducing retention time as required for conventional clarifier. This results in effective reduction in the equipment sizes as well as substantial savings in the utilization of treatment chemicals.

As such, the solids contact clarifier provides a means for chemical addition and mixing, flocculation, and upflow clarification in a single unit. In operation, raw water, chemicals, and a large quantity of recirculated precipitates are thoroughly mixed in the draft tube (mixing section). These are maintained in intimate contact for a prolonged period under the detention hood (flocculation zone). The contact between the water treatment chemicals and the preformed precipitates causes additional precipitation, and the recirculated floc particles rapidly grow to an exceptionally large size and high density. In addition, the large volume of recirculated precipitates provides an adsorptive surface that maximizes the reduction of color and organics.

Tube Settler

For small flow rates and low cost solid liquid separation in water and waste water treatment

Tube settler systems are an inexpensive solution for small flow rate drinking water and wastewater plants to increase treatment capacity, reduce new installation footprints, improve effluent water quality, and decrease operating costs. Constructed of lightweight PVC, tube settler modules can be easily supported with minimal structures that often incorporate effluent troughs and baffles. Modules are available in a variety of sizes to fit any tank geometry and tube lengths to accommodate a wide range of flows. With years of experience and extensive knowledge of the water treatment process, ionic can provide full process design for economically packaged systems.

Tube settlers are not as efficient as lamella Inclined Plate Clarifier. However they are popular and widely sued for its low cost and small foot print.

Typical application

• Potable water clarification
• Waste water clarification
• Sewage treatment system secondary clarifier for biomass removal

Dealkaliser

Dealkaliser - When Alkalinity and Carbonate hardness reduction from water is required

Dealkalisation involves removal of the Temporary Carbonate Hardness (Hardness associated with Alkalinity) in the raw water in a Weak Acid Cation, so that the Total Dissolved Solids reduces along with the Hardness. To remove the free CO2 liberated in the Weak Acid Cation, a degasser system is used. The effluent from cation column will be acidic in nature and hence pH correction will be required. Application areas are boiler feed, cooling tower make up, carbonated soft drinks and partial desalination to reduce hardness, alkalinity and TDS in the raw water. The Operation of the Dealkaliser is automatic.

Dealkaliser has many operational benefits in a water treatment process compared to having softening plant alone for removing hardness from water. The benefits are:

• Selectively removes temporary carbonate hardness from the feed water
• Has high selectivity for hardness associated with alkalinity
• Weak acid cation exchange resin has very high operating exchange capacity ( gms. salt removed/ Litre of resin used) compared to softener resins.
• Very high regeneration efficiency (5% extra regenerant required based on stoichiometric requirement) compared to softener resins (softener resins require extra salt of 50-60% stoichiometric requirements.

Typical applications

• Cooling water make up
• Boiler feed water for low pressure boilers
• Beverage production
• Bottle washing water
• Pretreatment to R.O plant

Mixed Bed Demineralisers (MB)

There are many industrial processes in which the presence of any dissolved salts in water can cause problems. Removing all the dissolved salts from water is called deionisation or demineralisation. Processes that need high purity water include: High pressure boilers, Chemical manufacture, Toiletries and cosmetics production, Humidification systems, Battery top-up, Surface finishing, etc.

For industrial processes requiring high purity water, the most widely used purification technology is twin bed ion exchange deionisation. The ion exchange resins are contained in two separate pressure vessels and flow through them in series. Raw water enters the cation exchange vessel and passes down through the resin bed where calcium, magnesium, sodium and other cations are removed from the water in exchange for hydrogen ions. The water then passes through the anion exchange vessel where chloride, sulfate, bicarbonate and other anions are removed in exchange for hydroxide ions. When the hydrogen and hydroxide ions on the resins have been replaced by the cations and anions from the water, the deionisation reaction stops and the resins need to be regenerated.

Industrial Mixed bed demineralisers consistent of a single column pressure vessel in which strong acid cation and strong base anion exchangers resins are intimately mixed together. Water passing through the exchanger repeated comes in contact with these resins and is thus in effect subjected to almost infinite number of demineralizing stages. Demineralised water of very low conductivity (<1 .0 micro Siemens/cm) and low reactive silica content is produced.

MB units are regenerated with acid and alkali upon exhaustion of the resin. Generally two bed demineralized water is taken as feed to the MB unit and occasionally Ro permeate and filtered water having < 100 ppm TDS can be fed to the system.

Continuous Electro Deionisation System

Continuous Electro Deionisation is when chemical free Deionisation / Demineralistion is required

CEDI process means it removes ions from liquid by using electrically active media and by using electric potential to influence the ion transport. In the module, direct current is applied to the anode (positive electrode) on one end of the module, and to the cathode (negative electrode) on the other end. Compartments of CEDI are hydraulically in parallel and electrically in series. Resins are filled between Cation & Anion exchange membrane in the dilute chamber, because resins are more conductive than solution. This electric potential drives the ions captured by the ion exchange resins through the membrane. Because of the electric current, water catalyze splitting continuously due to that resins are continuously regenerated in the module, they do not become exhausted. This continuous electro- regeneration enables continuous production of multi-mega ohm water without the need for chemical regeneration or downtime.

Application areas

Capacitive Deionisation (CDI)

With the need for water increasing day by day due to population growth and increased industrial activity the time has come to think seriously about sustainability and reducing your water foot print. In addition to this reducing power, chemical and waste becomes important. This calls for an alternative innovative approach to water treatment than traditional approach.

IONIC introduces an innovative patented treatment technology called Cap Di that takes into account the above requirement and reduces the life cycle cost.

For Desalination, an innovative technology called Capacitive Deionisation - CDI is used. This technology can treat ground or surface water containing high dissolved salts to take out all contaminants like Fluoride, Nitrates, Arsenic, Hardness etc, to produce clean drinkable water and process water that meets WHO/IS standards. With limited single source supply many industrial units are forced to depend on multiple sources with different characteristics for various processes. This affects the treatment process as well reduces the reliability of the same.

This technology differs from the traditionally Reverse Osmosis systems as it discharges much less waste water, consumes low power and does not use chemicals during purification / treatment process. The overall operating costs are also low since it does not use semi permeable membranes and the total consumables are less.

How this works ?

The system comprises of "CDI Cells" which has several electrodes stacked in a compact case
Water is sent through these electrodes at a very low pressure and as water flows through these electrodes a voltage difference is applied (forming a capacitor) between them to disassociate ions present in water.CDI Cells uses different coupled electrodes contained in a pressurized container, these electrodes are placed at a distance of 100 microns to ensure maximum contact with water.

As water moves through these electrodes, a direct current at a potential difference of < 1.6 Volt is supplied. This creates an electrostatic field that attracts the ions dissolved in water to the electrodes. Operating as low voltages, electrolysis and gas production will not occur. The result is the partial or total demineralization of the water.

The electrodes behave like those of a normal condenser. At a certain point, the ions will cover the whole surface of the electrodes saturating them. When this occurs, the system senses the potential difference and automatically reverses the polarity of the electrodes. By doing so, the ions that are stuck to the electrodes gets disengaged. The result is a high concentration of dissolved ions that are now sent to drain.

Once the ions get discharged, the polarity is brought back to normal and the entire process of deionization starts again. This entire process is done automatically in through a smart controller that senses when to regenerate the electrodes and when to start production.

The picture below shows the process of deionization and regeneration in CDI cells.

Typical applications

• Drinking water treatment – brackish water desalination
• Process water treatment
• Cooling tower make up
• Boiler feed water make up

Ultra Filtration System

To protect the down stream RO or CDI system from fouling we propose a ultra filtration system which will remove ultrafine particulate matter, algae and bacteria and make the water suitable for further desalination.

Ultrafiltration (UF) is a pressure-driven process that removes emulsified oils, metal hydroxides, colloids, emulsions, dispersed material, suspended solids, and other large molecular weight materials from water and other solutions. UF membranes are characterized by their molecular weight cut-off.

UF excels at the clarification of solutions containing suspended solids, bacteria, and high concentrations of macromolecules, including oil and water, fruit juice, milk and whey, electrocoat paints, pharmaceuticals, poly-vinyl alcohol and indigo, potable water, and tertiary wastewater.

Avoid Pretreatment – The IONIC UF system's high flux and solids tolerance properties can eliminate the need for costly clarifiers and chemical pretreatments in tough applications.
Less Downtime – Polyester reinforced membranes and a unique single potting design help to avoid downtime associated with frequent cleaning cycles, sludging and fiber repair.
Less Chemicals – Superior chemistry and a tight pore structure deliver more stable membrane performance without the need for extensive chemical cleans.
Simple Operation – Minimal system connections, an intelligent user interface and outstanding membrane reliability make IONIC UF one of the easiest-running filtration systems available.
Save Money – Superior output, simplified operation, reduced maintenance and pretreatment costs and a compact footprint all add up to cost savings for you!

Ultra filtration or UF is a semi - permeable membrane controlled pressure driven process capable of performing a variety of selective separations. In Ultra filtration, the process feed solution flows across a membrane with pore diameters in the range of 10 angstroms to 200 Angstroms. This is a pressure driven membrane separation process that separates particulate matter from soluble components in the carrier fluid (such as water). UF membranes typically have pore sizes in the range of 0.01 - 0.10 µm and have a high removal efficiency for bacteria and most viruses, colloids and silt (SDI), the smaller the nominal pore size, the higher the removal efficiency. Most materials that are used in UF are polymeric and are naturally hydrophobic. Common polymeric materials used in UF include: Polysulfone (PS), Polyethersulfone (PES), Polypropylene (PP), or Polyvinylidenefluoride (PVDF). Although these materials can be blended with hydrophilic agents, the hydrophilic additives can reduce the membranes ability to be cleaned with strong levels of disinfectants such as peroxide or hypochlorite to sufficiently remove bacterial growth.

IONIC uses several different type of membranes depending on the application and feed water characteristics. Contact us with your requirement and we shall recommend a suitable system.

TYPICAL APPLICATIONS

Nano filtration is a technique that has prospered over the past few years. Today, nano filtration is mainly applied in drinking water purification process steps, such as water softening, decolouring and micro pollutant removal.

During industrial processes nano filtration is applied for the removal of specific components, such as colouring agents. Nano filtration is a pressure related process, during which separation takes place, based on molecule size. Membranes bring about the separation. The technique is mainly applied for the removal of organic substances, such as micro pollutants and multivalent ions. Nano filtration membranes have a moderate retention for univalent salts.

Typical Applications

Reverse Osmosis Plant

Reverse Osmosis Plant - When Desalination of Brakcish and sea water is required

Reverse osmosis process is a membrane process in which a synthetic semi permeable membrane is used to separate water from dissolved impurities. When a semi permeable membrane separates a dilute and concentrated solution of salts, due to Osmosis, the water from the dilute solution side passes through the membrane to the concentrated side till osmotic equilibrium is attained. Now, if pressure is applied and increased gradually on the concentrated side, the flow of water continues to reduce till the applied pressure is equal to the osmotic pressure. Any pressure in excess of the osmotic pressure reverses the direction of flow of water and water from the concentrated side enters the dilute side. This process is called the Reverse Osmosis.

The water fed to the RO plant where the water gets separated into two streams, viz. Permeate containing very little amount of dissolved impurities and Reject having more concentrated impurities. The Permeate is collected in the Permeate Water tank. Depending on the feed water characteristics the recovery will be decided and it can be between 30-75%.

IONIC offers both manually operated and fully automatic systems. Optionally the fully automatic systems can be supplied with proprietary smart "MATRIX" Real Time Monitoring system and Remote monitoring system. With the inbuilt "PDP Indicator" in Matrix Real time monitoring system can be used for finding out how efficiently the R.O systems are working and when to clean the membranes.

Ionic Engineering for the first time in India has developed an advanced Reverse Osmosis control system which measures in real time the following parameters for easy and reliable operation of the membrane based system. This feature is unique to our design and is not available in competetive systems.

It is well known that Reverse osmosis systems can be very sensitive to changes in the operating conditions. For example, temperature changes or feed water concentration changes can greatly affect either the product flow or the product conductivity. R.O systems design and operating conditions are different and hence the data like flow, pressure, salt rejection needs to be normalized to the start up or standardized conditions which is seldom the case. Fouling of the membranes due to particles, in organic salts, biofilm etc. affects the membrane process and unless the data is properly collected and analysed will result in poor performance and if corrective action is not taken in time, may lead to irreversible damage to the membranes.

Th system automatically stores the start up value and compare this with actual present normalised value and indicates in clear English text what is the condition of the membrane and system performance.

This system aslo helps in taking a decision on timely cleaning of the membranes and help in cleaning process. The advanced proprietary software developed by us calculates the allowable decline in performance value and displays in bar graph for easy understanding by the operator.

The system also has a unique MATRIX PDP (Permissble Decline in Performance) indicator which indicates whether the normalised values are with in the limit or out of the range so that the nature of the problem can be easily identified.

IONIC went one step ahead to make the monitoring and trouble shooting easier. We incorporated articial inteliigence in our "EASY CONTROL" system with which data is analysed and possible problems like scaling, fouling, O ring and membrane damage are predicted to take the guess work out of the operators mind.
