Right Water Systems is a Noida based manufacturer of De-Mineralization Plant which are available in Two Types, Mainly Two Bed DM Plants and Mixed Bed DM Plants. However, DM Plants are also available with Weak Base & Strong Base Cation & Anion Exchanger. DM Plants are also available with De-gassification System to remove alkalinity physically without using chemicals (Saves NaOH).
Right Water Systems manufactures and supplies Standard DM Plants with FRP / Mild Steel Rubber Lining & SS 316 L (Quartz Lined) construction.
Right Water Systems manufactured DM Plants (Two Bed & Mixed Bed units) are available in various sizes having cation and anion exchanger unit with 200 mm to 2000 mm diameter with either Valves or Multi Port Valve depending upon the sizes and customer requirement.
In Two Bed DM Plant, Strong Acid Cation Exchanger and Strong Base Anion Exchanger resin are used for reducing Total Dissolved Solids up to 2 – 5 ppm. To check the treated water quality at the outlet, conductivity meter is provided. Degasification unit is also provided to decrease the load on Anion Unit.
Mixed Bed Units are used in series with Two Bed DM Plant as a polisher unit which can produce treated water having conductivity < 1 mS/cm. Cation Polisher Unit is also available to achieve Acidic Water Quality for Specific applications. DM Plant produce Treated water having Conductivity less than 10 mS/cm (for Two Bed) and less than 1 mS/cm with pH as desired. The plant designing capacity 100 to 2,00,000 Ltr. Per Day depend on water property with water your requirement. The demineralisation process utilizes acid regenerated action resin & caustic regenerated anion resin to remove minerals from water. We offer DM Plants of different sizes as per requirement of the customers. Trolley mounted automatic operation DM Plants are also available for small industries and laboratories Demineralization or Deionisation is the process of removing mineral salts from water by using the ion exchange process. With most natural water sources it is possible to use Demineralisation and produce water of a higher quality than conventional distillation. Right Water Systems Manufacture a Wide range of custom-built softening, Dematerializing plants for industrial process water applications, with inherent design to conserve water, and save costs. They are available in different sizes and materials, manually operated or fully Automatic, & ready to install & are available as standard models or custom built versions for specific needs.
A Typical two-bed DM Plant consists of two FRP/MS Rubber lined Pressure vessels connected in series along with its internal fittings. The first unit consists of high capacity strongly acidic cation exchange resin, which converts positive ions of salt and replaces them with hydrogen ions to form respective acids, which are absorbed in next vessel by strongly basic anion exchange resin. The water obtained by this process shows conductivity less than 20 µ S / cm at 25o C and total dissolved solids less than 10 ppm.
Further high purity water can be achieved by Mixed Bed Deionisers, which are designed to produce high purity treated water. They can be used as polishing units after two bed DM Plant to obtain high purity water. Mixed Bed Deionisers are single column units, filled with strongly acidic cation and strongly basic anion exchange resins mixed together.
There are four distinct stages in the operation of Deionisers
In the Service cycle the water enters the vessel and passes through the Resin bed of the respective exchanger
After the resins are exhausted, the bed is backwashed. Backwashing is carried out by a uniform upward flow of water through the resin bed. The backwash step expands the resin bed releasing any entrapped particulate matter & removes the channelling in the resin column if occurred during the service cycle.
When the ion exchange resins loose all the exchangeable ions, they require regeneration to restore them back to hydrogen or hydroxyl form depending upon whether they are cation or anion resins. To achieve this 4 – 5% concentrated solution of Hydrochloric acid is used for cation resin and a 4% – 5% concentrated solution of caustic soda for anion resin. Sulphuric acid can also be used for Cation Regeneration but the concentration of acid during injection must be kept at minimum, such as to prevent calcium sulphate precipitation on the resin.
