Bio-ceramisite filter material (Ceramisite)
Ceramsite is made of high-quality clay, pore former, binder, ball milling, sieving, molding and sintering. Spherical particles with uniform particle size, hard surface and well-developed micropores, large specific surface area, high porosity, strong dirt interception ability, high filtration rate, biological bacteria have strong adhesion ability, rapid reproduction, and high film-forming efficiency. This is a substitute for quartz sand in biological filters.
