Ion Exchangers
Paramount designs, manufactures, deliver DM Water Plants for various applications including boiler feed water for high pressure boiler in the power station, with the quality standard required for the purpose.
Paramount can deliver these in various combinations for specific requirements, tailor made on a turnkey basis, or as package units depending on the size & logistics for any flow capacity. Paramount designs three plants in manual or semiautomatic made based on PLC or DCS operations.
The common configurations are shown below. The largest installation delivered by paramount is 600 m3/hr (4x150 m3/hr chains) having water quality of silica less than 10ppb and Conductivity of less than 0.1 micromole/cm.
Demineralization is the term used for removal of the Dissolved Salts from the Water. The source of water can mainly be classified into two groups.
• Surface water - Rivers, streams, ponds, lakes, reservoirs, etc.,
• Underground water - Open wells, tube wells, springs, etc.,
The salts leached out from the earth and the rocks get dissolves in the water. So the nature of salts and the contaminants in the water depends on the surroundings. For example, where the water flows through lime stone and gypsum rocks, the hardness will be high. Hardness is caused due to the presence of Calcium and Magnesium.
So every water is different in their salt content and the type of salt. The salts deposit on the surface of the container and acts as an insulator. Greater the temperature of the water greater is the problem. These deposits called “scales” are very hard and difficult to remove. When scales are formed it affects the heat transfer and at a certain stage the container is damaged.
Hence, the water requires to be treated before it is used for a particular purpose. Depending on the end use, various economical treatments are possible.
The salt content can be reduced to near zero (Trances) by proper selection of the process & method of Regeneration.
By adopting Counter current regeneration of cation Exchanger and Anion Exchanger, We can get superior quality of water at the outlet of Anion Exchanger and pass the Anion treated water through the Mixed Bed polisher. We can get the desired quality with Conductivity less than 0.1 Micromo / cm and Silica less than 0.01 ppm as SiO2.
