Shale of knowledge

Shale filter using natural rock - shale as ceramic proppant suppliers materials, high temperature roasting refined. Shale its non-toxic , tasteless , compression wear , corrosion , Shale and has a good adsorption properties and strength for purifying all kinds of water quality. Also for floral arrangements soilless cultivation , its light weight, compressive strength, heat , frost , shock , radiation , etc. can also be used to make building energy-saving materials. Shale is a new filter biofilm carrier filler. Shale using shale or clay, adding the active agent , the high temperature calcination , finishing. It has good physical, chemical and hydraulic characteristics, large surface area ratio, porosity, adsorption interception ability. How lightweight proppant , multi-angular , rough and easy to hang the film , and a certain mechanical strength , is an ideal carrier microorganism
