We offer Industrial Pressure Sand Filters, which are used for removing color, taste, sometimes BOD, odor, phenol and other obnoxious matter. In this filter, the water is passed under pressure through bed media and granular activated carbon layer. The activated carbon layer also said to be a polishing unit, which is extensively used in tertiary treatment of effluent/ sewage treatment plants, so that they can be re-used and recycled.
