Diatomaceous micropore ceramic filter using high-quality double-sided diatomite as raw material, is molded in1200 ℃high temperature firing into the advanced filter materials. It has extremely high physical and chemical stability, can be in neutral, acidic, alkaline conditions effective to filter the water suspended solid matter, colloid, bacteria etc.. Diatomaceous micropore ceramic filter using double-sided has three national patent double-sided filter technology, can reduce the filtering precision, greatly improve the filtration flow, the pressure in the 0.0025MPa maximum flow reaches 7L/h, the use of more extensive scope.
