Industrial Water Treatment

Industrial wastewater discharge can carry a variety of pollutants that can adversely affect the ecology of receiving lakes, streams and rivers.Vadivel Cocotech offers a variety of advanced industrial wastewater treatment technologies to prevent the migration of contaminants into protected waters.

Industrial Water Filters

Most industrial applications require treated water to maintain the attributes of the product being manufactured and also protect the process equipment from damage. In most cases treating it with a suitable activated carbon filter as a stand-alone unit or in conjunction with other filtration technologies is preferred as a final stage filtration step. Vadivel Cocotech has recognized this purification requirement and has developed a superior range of activated carbon products to carter to stringent water quality requirements demanded by a number of industries.

Our products with high dechlorination kinetics and hydrocarbon adsorption capacities are used significantly in process water treatment to ensure zero damage to ion-exchange resins used at subsequent stages in the treatment flow. These products are available from a multitude of particle sizes and particle size distributions as well as adsorption characteristics to suit your exact requirement.

Desalination Systems

Removing salinity from water through desalination systems to make water fit for consumption is vastly practiced in many countries globally. The reverse osmosis systems and membrane filters used in these systems are highly sensitive to organics, chlorine, dust and other impurities. Vadivel Cocotech is your ideal solution to prevent this disruption. By using our activated carbon solutions designed for water pre-treatment in desalination systems, you can scavenge residual chlorine from microbial disinfection and prevent organic fouling from organic matter present.

These products are specially manufactured to have high purity and resistant to attrition to avoid any release of dust or other impurities to the desalination system. Not only do we offer you a quality and superior product but we also provide engineering and R&D solutions for system design and deciding optimal operating conditions.

Condensate Boiler Feed Water Treatments

Water used as condensate boiler feed requires very high purification standards. Fresh water from municipal supply or any other source may contain Chlorine and organic contaminants which can damage ion-exchange resins for water treatment while recirculated condensate water may be contaminated with various oils, hydrocarbons and other organics and inorganic from machine wear and tear. Vadivel Cocotech activated carbons successfully remove these various contaminants in both fresh and recycled water, de-oiling the condensate and purifying the water flow, thus effectively protecting the ion exchange resins and other sensitive equipment from damage and deterioration.

Silica, a common fouling agent in standard coal and coconut based activated carbons can also damage ion exchange resins, boiler tubes and turbine blades. This is why Vadivel Cocotech’s cutting edge products for boiler feed water treatment are designed to have the lowest silica and ash levels in the industry resulting in significant improvement of machinery lifetime and reduction of maintenance costs and superior performance of the carbons.
