Potable Water Treatment

Potable or drinking water is a commodity with stringent requirements of being safe and pure. Vadivel Cocotech’s range of Granular Activated Carbons (GACs) is your ideal solution in making drinking water free from taste and odour forming compounds such as MIB and geosmin, undesired colours, endocrine disrupting compounds and other micro pollutants, chlorinated hydrocarbons, Trihalomethanes and other disinfection byproducts, VOCs, pesticides and their byproducts.

We offer high quality, standard, and specially processed products with low dechlorination half values, superior flow characteristics, consistent particle size distributions to facilitate pressure drop and adsorption kinetics requirements, extensive pore structures with an ideal balance of both adsorption and transport pores, and high mechanical strength resulting in minimal operational and pressure drop issues. These superior features have made our granular carbon products the industry choice for Point of Use (POU) and Point of Entry (POE) water filters.

Municipality Water Treatments

In the treatment of municipal water, removal of organics including VOCs, inorganics and toxins inherent in the rivers, lakes, reservoirs and other surface water sources and ground water systems is essential. Vadivel Cocotech has introduced a tailor made series of products for surface and ground water treatment in municipality water treatment systems to deliver consistent performance in removing these contaminants.

These products are also geared to adsorb hazardous pesticide and herbicide residues, chlorinated hydrocarbons, disinfectant by products, inhibitory compounds for biological treatment systems, non-biodegradable organic compounds, and undesired coloured and smell compounds. Our carbons are effective in lowering of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Organic Content (TOC) and toxicity. In addition, the high purity of the carbon products prevents the release of contaminants that may damage sensitive membrane systems used in other in-process filtration systems. We also offer custom designed products and total purification solutions to best suit your requirement.

Chloramine Removal

Chloramine, a drinking water disinfectant affects the quality of water in terms of taste and odour, while being a health hazard in high concentrations. It is also a difficult contaminant to remove at the point of use. This calls for a special selection of catalytic activated carbons. Vadivel Cocotech’s R&D arm has developed a distinctive selection of catalytic carbon products with very high reaction kinetic for the removal of chloramines from potable water which are specially designed to carry a large number of catalytic sights compared to products from other carbon suppliers to react with and remove different types of chloramines, including monochloramine.

This product series includes carbons customizable for your exact pressure drop and particle size requirement and to support your existing operation conditions. The high efficiency and consistent performance demonstrated by these products extend the bed life of the carbon whilst cutting short the required contact time, and the size of the equipment which is translated into reduced cost for you.

Soil Water Treatment

Due to extensive usage of organic and inorganic compounds in agriculture, the soil water in some areas is highly polluted. Removing these contaminants, mostly VOCs and chlorinated hydrocarbons which are in a very stable state in soil water, has become an enormous task. As a remediation, Vadivel Cocotech Activated Carbons are recommended for use either as a stand-alone treatment unit or in conjunction with other treatment units as a part of a multistage system.

Our carbons are capable of reducing TOC (Total Organic Carbons), TOX (Total Organic Halides), VOC (Volatile Organic Compounds) and DOC (Dissolved Organic Compounds) in soil water. Vadivel Cocotech Activated Carbon technology and assurance of quality ensures a consistently high performance in terms of capacity, rate of adsorption and long working life in the circuit.
