Embodiment

[0051] The invention is practiced in the treatment of wastewater in the latex glove manufacturing industry. The present invention is intended to treat industrially produced wastewater to meet the wastewater discharge standards established by the Malaysian Department of Environment (DOE) under Standard B of the Environmental Quality Act (EQA) 1974 / 2009.

[0052] Table 2 shows a comparison of the characteristics of wastewater from industry with the standards established by DOE according to Standard B of EQA 1974 / 2009.

Abstract

The present invention relates to a composition for treating waste water, which comprises: by weight percentage, 43.7-46.2% bentonite; 24.1-25.9% aluminum sulfate (Al2(SO4)3), wherein, the particle size of Al2(SO4)3 is 18 ‑74 μm; 19.2‑20.8% ceramic powder; 4.8‑5.2% chitosan, wherein the chitosan has a particle size of 44 μm; and 4.8‑5.2% calcium carbonate (CaCO3). Further disclosed are methods of using the composition for treating wastewater. A device for dispensing said composition into wastewater is further disclosed.

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...
