Treatment of water

Abstract

Abstract PURPOSE: To treat water safely and cheaply by using cement as a flocculant or an auxiliary flocculant for treating water to improve the settleability of flocks. CONSTITUTION: Cement is used as a flocculant or an auxiliary flocculant for treating water such as service water, sewage or industrial waste water. Since various chemical components in cement are applied to pharmaceuticals, an adsorbent, etc. and have high specific gravity, they facilitate the growth and settling of flocks in water treatment. The flocks are crystallized, hardened, and converted into favorable harmless solid matter by drying in the sun. Thus, water is treated with cement cheaply and efficiently.
