FIBROUS BASIC MAGNESIUM SULFATE MASSIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a basic magnesium sulfate massive material which has high stability in water and whose particle shape and size can be easily controlled and a waste water treatment unit using the fibrous basic magnesium sulfate massive material as a waste water treating material. SOLUTION: The fibrous basic magnesium sulfate massive material is formed by bonding a number of fibrous basic magnesium sulfate having 5-200μm average length and 0.2-1.0μm average diameter with a binder to expose at least a part of the fiber surface of the same. The waste water treatment unit is structured by filling the waste water treating material 3 comprising the fibrous basic magnesium sulfate massive material into a space between an outside cylindrical body 1 composed of a porous material and an inside cylindrical body 2 composed of the porous material which are concentrically assembled.
