Carbon filter media tanks look like multi-media filter tanks. We are installing sand media for the multi-media filter tank and activated carbon for the activated carbon filter tank. But in some applications, we can add carbon and sand media at the same time in the multi-media filter tank.

Design flow rates should be 1 GPM/ft3 for TOC removal and 2 GPM/ft3 for chlorine removal when used for RO pretreatment. The expected TOC removal efficiency ranges from 25% to 80%, depending on the nature of the organics. Chlorine can be removed to less than 0.05 ppm. Activated carbon can also be used to remove chloramines in the same manner as chlorine, however, the contact time must be greater than for chlorine removal. For a 12 × 40 mesh carbon, contact times up to 30 min are required. Catalytic activated carbon can also be used to reduce the contact time for chloramine removal.
Activated carbon is derived from natural materials such as bituminous coal, lignite, wood, fruit pits, bones, and coconut shells, to name a few. The raw materials are fired in a low-oxygen environment to create char, which is then activated by steam, carbon dioxide, or oxygen. For most industrial applications, bituminous carbon is used. This is because the smaller pores size, higher surface area, and higher density than other forms of carbon give bituminous carbon a higher capacity for chlorine.

Carbon can also come in one of 3 forms: powdered (PAC), extruded block (CB), and granular (GAC). Most industrial applications used GAC as this is the lowest cost of the 3 types of carbon media for activated carbon filter tanks and this type of carbon can be reused. All carbon is characterized by a high surface area. A gram of carbon can have a surface area in excess of 500m2, with 1,500m2 being achievable. A high surface area is necessary for the reduction of organics and chlorine within reasonable contact time in activated carbon filter vessels.
Our activated carbon filter tank materials are FRP, Stainless Steel 304, Stainless Steel 316, and Carbon Steel. Also, we can use the same material for a multi-media filter tank.

Our Carbon Steel activated carbon filter vessel outside is painted with rust protection chemicals and epoxy paint. Color is optional. Activated carbon filter tank and multi-media filter tank thickness can be designed as regards working pressure. All filter media filter tanks and activated carbon filter tanks are optional inlet and outlet flange sizes. And also our activated carbon filter vessel has a 350-400mm main entrance to make cleaning easy.

Carbon filters are used to remove organics (as TOC) and free chlorine from RO feed water.
Bituminous carbon is used for industrial RO pretreatment applications.
Brackish and Seawater
Activated carbon filter tanks are used to reduce the concentration of organics in RO feed water.
Activated carbon filter vessels are also used to remove oxidants such as free chlorine from RO feed water.
Organics are adsorbed on carbon particles for removal from water.
Removal of chlorine involves an oxidation/reduction reaction with the carbon particles, where a transfer of electrons occurs from the activated carbon to the chlorine (the carbon acts as a reducing agent)
