Abstract

The present invention relates to a composition for treating waste water comprises, by weight percentage,: 43.7 - 46.2% bentonite; 24.1 - 25.9% aluminium sulphate (AI2(SO4)3), wherein the particle size of the AI2(SO4)3 is 18 - 74pm; 19.2 - 20.8% ceramic powder; 4.8 - 5.2% chitosan, wherein the particle size of the chitosan is 44μm; and 4.8 - 5.2% calcium carbonate (CaCO3). Further disclosed is a method of using the composition for treating waste water. In another further disclosure, there is introduced an apparatus for dispensing the composition into the waste water.

Description

technical field [0001] The present invention relates to compositions for treating wastewater, and more particularly, to compositions for treating wastewater by binding and agglomerating wastewater particles. Background technique [0002] Water covers almost 71% of the Earth's surface and is necessary for all known forms of life. Safe drinking water is vital for humans and many other life forms such as aquatic plants and animals. Fortunately, for small amounts of waste water and pollution, nature can handle itself. However, with the increasing number of industries, houses, and factories that seriously affect water quality, nature cannot handle it by itself due to the huge amount. One of the ways to address compromised water quality and reduce the burden on nature is to treat water for domestic, industrial and commercial use before it is released into the environment. [0003] Wastewater can be defined as used water that includes suspended and dissolved matter and particles...
