Process Water Treatment II

The dealkalisation process reduces the alkalinity in water. Along with alkalinity, it also reduces hardness and sodium associated with alkalinity. These reductions reflect in the content drop of dissolved minerals in water.

The growing demand for ultrapure water by industries has paved way for systems that deliver superior quality water products. The EDI system is an effective design combining two well established and proven water purification technologies – electrodialysis and ion exchange resin deionisation. In other words, EDI is a continuous process for producing high purity water using ion exchange membranes, resins and electricity.

Barrelyene Chemicals resins used for conventional water treatment applications such as softening, deionisation and dealkalisation are manufactured in an automated ISO 9001 & 14001 certified facility. Lower rinse volumes, high capacity, superior life pattern and proven track record make Barrelyene Chemicals resins a preferred choice.

Barrelyene Chemicals nuclear grade resins have been developed after intensive research and have exceptionally high bead strength, low levels of metal, chloride and organic impurities. The resins are used for a number of applications in the nuclear power industry.

Comprises a family of automatic twin-bed deionisers incorporating state-of-the-art counterflow ion exchange technology. Operation cycle of these rapid-regeneration, skid mounted and packaged units are controlled by volume throughout, which is pre-programmed into the PLC according to the type of feed water. The ion exchange resins are never fully exhausted ensuring optimum deionised water production at all times. Regeneration of cation and anion beds is simultaneous hence, effluent streams are largely self-neutralising, reducing waste disposal costs and environmental impact.

The condensate polishing unit removes ‘crud’ – mostly consisting of sodium, chloride, silica and carbon dioxide. Condensate polishing units are typically installed for super thermal power stations with the main objective of improving the boiler water quality. The benefits of condensate polishing are quicker start up and as a result full load conditions are reached early giving economic benefits. Orderly shutdown is possible in the case of condenser tube leak conditions.

We offer a complete range of Barrelyene Chemicals gel, isoporous and macroporous as well as cation and anion exchange resins for water and waste water treatment and a host of speciality applications – pharmaceutical excipients, food, catalytic, and nuclear grade resins, chelating resins for brine softening, resins for sugar purification and many more.

We manufacture a variety of high purity Barrelyene Chemicals resins designed for the purification of potable water. These resins have very low organic impurities. The applications include softening, water disinfection and nitrate/arsenic/fluoride/iron removal.

Barrelyene Chemicals catalyst grade resins have superior particle integrity, high surface area, controlled porosity and lower moisture content. These unique properties make them an excellent choice as catalyst in a variety of chemical reactions.
