Filtration Media for Wastewater Treatment

Limestone, on contact with acidic waters, slowly dissolves the calcium carbonate ,media, to raise the pH. This effectively neutralizes the water and reduces the potential corrosion of copper and other metals found in plumbing systems. Periodic backwashing is necessary to maintain high service flow rates and prevent packing the ,filter, bed.

Selection of filter media is dictated by the sizes of particles that are to be removed from the water. In a wastewater treatment train with multiple filtration steps, they are sequenced to remove the largest particles first, stepping down to the smallest particle removal. Common examples of filters include media filters, bag filters, and membranes.
