Hydrocons offer worlds latest electrodeionisation technology to generate high purity water. EDI cell can meet stringent water quality such as USP standards. The RO permeate water having conductivity less than 20 us/cm fed to EDI cell. The ion-exchange takes place on ultra pure resin bed. These absorbed ions of resins pulls towards concentrate chambers by respective electrode, these pulled ions continuously flush in concentrate chamber with small amount of RO permeate water & finally goes to drain.

Continuous Electro-Deionisation systems (CEDI) for producing pure water.

Introduction :

With the advent of new technology it is now practical to deionise water without the use of cation and anion resins regenerated with acid and caustic solutions; this technology is known as Continuous Electro-Deionisation or CEDI.

The process was developed in 1980 and has since been perfected in the form of modular cells for use in high purity water systems as a polishing de-ioniser when feed with permeate from a Reverse Osmosis system, thus replacing the requirement for twin bed and mixed bed de-ionisers.Description of Continuous CEDI Cell:

CEDI systems are used as a post-treatment to reverse osmosis to further purify the permeate to produce water with a quality of 10 to 18 megohm depending on feed water quality and flow rates. The

CEDI units are modular in construction and can accommodate multiple CEDI modules.

Advantages of CEDI Cell over conventional EDI Systems

• Does not require chemicals for regeneration
• Compact in size
• Produces consistent water quality
• Economical running costs
• Modular in construction
• Safe process

Process Description :

CEDI system has an recovery of 95%. The 5% reject water from EDI can be feed back to the feed of RO System & hence the overall recovery of the system is 100% (approx.). CEDI consists of two chambers: the first is ion exchange chamber / frame consist of ultrapure cation & anion exchange resins, these resins are in mixed form. The second chamber is concentrate chamber. These chambers are arranged in alternate positions in EDI cell. The cation membrane & anion membrane forms the boundary of each ion exchange chamber. The cations present in the feed water are exchanged on cation exchange resins. These picked up cations push through resin towards the cathode & pass through the cation allowable membrane into the concentrate chamber. Also anions present in the feed water are exchanged on anion exchange resins. These picked up anions push through from resin towards the anode & pass through the anion allowable membrane into the concentrate chamber. All rejected ions in the concentrate chamber are continuously rinsed with a small amount of the RO Permeate water. This water having TDS not more than 25 30 ppm, can be recycle to the feed of Reverse Osmosis system. A part of permeate water when passes through the electric field of EDI cell, forms Hydrogen & Hydroxyl ions. These ions regenerate the cation & anion resins on-line.

A primary benefit of this system is continuous operation, as the ion exchange resin is regenerated continuously by electricity instead of regeneration chemicals. This approach eliminates the downtime, while reducing chemical usage and the need for waste treatment. No acid or caustic regenerate chemicals are required.

Hot water sanitizable EDI systems are also available for critical Pharma applications. Similarly EDI units with higher flow capacities and range are available for power plant applications.

The unit incorporates the following features:

• The complete unit is fully assembled and ready for use simply by plumbing it directly on to the permeate water supply from a Reverse Osmosis system.
• The complete system complies 21 CFR part 11 and backed with complete validation documents.

Hydrocons softener is a upflow / downflow unit operating on the principal of ion exchange. The softener is charged with strong acid cation exchange resin in sodium form. These resins exchanges sodium with hardness causing calcium & magnesium ions present in the raw water. In this process the water at the outlet of softener gets softened. The softened water will have hardness less than 5 ppm (commercially zero). The softeners are custom designed to handle various range of flowrates & hardness level in raw water.

Most and least tolerable chemical impurities in water are the hardness producing ions, calcium and magnesium in different concentrations and they are responsible for the hard scale that deposits and builds up in boiler tubes, pipe lines, condensers jackets, circulating system, cooking utensils and other equipment contracted by hot water. Hydrocons Softener is used primarily to produce Zero soft water by strong acid cation exchanger, which removes calcium and magnesium ions. The Hydrocons series of water softeners are designed for counter current regeneration with up flow rate and co-current regeneration with down flow rate. softeners are designed for longer operating cycles, low regeneration cost. The systems incorporate the proven technique of counter and co-counter currant regeneration flow rate to economically to suit the demand of soft water for medium scale industries and commercial use.

Hydrocons Demineralisation system is essentially used to produce demineralized water by removing dissolved ions from water by ion exchange process. The raw water to be demineralized or deionized is passed through 2 stages. Demineralisation comprising of cation exchanger followed by an anion exchanger. The treated water of the outlet of the anion is less than 10 ppm. To take care of these ions which have slipped out through the mixed bed (polishing unit) consisting cations & anoin exchange resins. The treated water at the outlet of the mixed bed unit is the purest form of demineralized water with residual dissolved less than 1 ppm & conductivity less than 1 us/cm. The system removes the carbonic acid formed due to breakdown of alkalinity by cation exchange. The system can be incorporated between cation exchanger & anoin exchanger unit to reduce the ionic load on the anion exchanger. This will reduce the operating cost of the system. Hydrocons Demineralisation system systems are custom designed systems so as to optimize the capital cost & minimize the operating cost of the system. Hydrocons delivers the latest concept of monosphere resin technology. The Demineralisation system with monosphere resin generates conductivity less than 1 us/cm without mixed bed. This reduces operating cost & down time. The manual & automatic operational Demineralisation systems can be provided.
