Adsorbents play a central role in water treatment applications. In addition to drinking water treatment, other fields are also leveraging the value of absorbents, including wastewater, groundwater remediation, and industrial wastewater, among others. Activated carbon is one of the most popular adsorbent materials for water treatment applications. It is eco-friendly, cost-effective and a highly effective adsorbent. Activated carbon’s unique microporous structure, large surface area, and excellent adsorption ability make it indispensable in water treatment applications. Apart from activated carbon, some of the popular adsorbent technologies include anthracite coal, ion exchange resins, molecular sieves, manganese dioxide and other materials.
Different Adsorbent Technologies Used in Water Treatment Applications
Activated Carbon for Water Treatment
Activated carbon (AC) is an effective adsorbent produced from different sources like wood, charcoal, nut shells, coal, and synthetic polymers. These materials are made from physical or steam activation, depending on the source material and desired properties of activated carbon. AC has a high surface area up to 1300 g/m3 and high internal porosity for the adsorption and trapping of undesired inorganic matter, organic and biological contaminants from wastewater. At Western Adsorbents & Catalysts, we are one of the leading activated carbon suppliers in India, supplying a comprehensive range of activated carbon suitable for every water treatment application.

Selecting the Right Activated Carbon for Your Specific Water Treatment Applications
Granular Activated Carbon (GAC): It is best in large-scale water filtration systems and Reverse Osmosis (RO) systems.
Powdered Activated Carbon (PAC): PAC is most suitable for emergency dosing and batch treatments.
Extruded Activated Carbon (EAC): It is effective for dechlorination and chemical removal.
Anthracite Coal in Water Treatment and Purification
Anthracite coal is a hard coal with a high carbon content of up to 98%. It is an excellent filtration medium for water purification and filtration, used alongside sand filters. The unique anthracite coal grain size and characteristics allow suspended particles to remain on the bottom. For improving turbidity extraction, choose anthracite coal with and greater capacity to retain solids.
Ion Exchange Resins in Water Treatment
Ion exchange resins are microporous beads made from polyacrylate and polystyrene. These resins are the most effective in getting rid of dissolved solids (TDS) and conductivity. The four basic industrial water treatment resins are:
Strong Acid Cation (SAC) Resins: Highly effective for water softening and removing hardness-causing ions like calcium and magnesium.
Strong Base Anion (SBA) Resins: For mineralization and high-purity water filtration, and a wide range of anions.
Weak Acid Cation (WAC) Resins: It is highly effective selective removal of hardness in high-alkalinity water and eliminates heavy metals.
Weak Base Anion (WBA) Resins: It is effective in removing strong minerals, organic compounds, odour, and colour and exhibits high operating capacity.
Manganese Dioxide in Water Treatment
In the water treatment industry, manganese dioxide filters are used effectively to remove iron, manganese and other contaminants, providing water treatment. With its strong catalytic properties and the ability to operate over different pH ranges, manganese dioxide accelerates oxidation and precipitation of contaminants.
Manganese Dioxide is Used in the Following Water Treatment Applications
Municipal water treatment
Residential and commercial filtration systems
Industrial water treatment
