11 Poamet POREMET POREMET 4th layer 5th layer reinforced using flat-tatami Zhijin net, so the pressure resistance strength is the largest among all media. It is excellent in backwashing due to its surface filtration structure. Sintered wire mesh is the most suitable for filteration where uniform filter rating is required. Using a dutch woven wire mesh in the fourth and the fifth layers for reinforcement makes POREMET the most pressure-resistant in our lineup. As this is surface filter medium, backwash cleaning is easy.
