The "Dual Media Filter" is a filtering system suitable for both clean water and sewage, ideal for the fine filtration of wastewater in industries like oilfields and refineries. This filter utilizes media such as anthracite coal and silica sand as its filtration material. It employs different combinations of these materials according to specific water treatment requirements. During filtration, oily wastewater flows through the filter layer from top to bottom, where oil and suspended particles are intercepted. After backwashing, suspended particles and some oil are removed. The filter media undergoes aeration and water backwashing to ensure good regeneration. This product boasts features such as a compact structure, comprehensive accessories, stable operation, easy operation, thorough backwashing, and simple maintenance. It finds extensive application in treating oily wastewater.
