Sewage treatment filter foam

Description of sewage filter foam 1) Application: The sewage filter foam is used as suspension biological filler which has very high efficent on various wastewater treatment engineerings. especially remove ammonia nitrogen in leatherworking process, remove COD in hard-degradation sewage, decoloration treatment in textile printing, deodorization treatment in various oganic exhaust gas, etc. 2) Appearance: we can cut the foam as customers' demand. Usually, we cut it to small ball, then put 6 balls into porous pellets. 3)Density: 1.05-1.20, the ballslightly heavier than water, so they can fully soak in water. 4)Technical features: the porosityis more than 95% it has very good airpermeablity and high mechanical strength. They make filter materials very small flow resistance, high efficient transudation.
