Use of Aloe-Vera Gel as a Coagulant in the treatment of Drinking Water

Abstract

Water is connected to each and every living forms of life on earth. An adequate, clean, reliable, accessible and safe drinking water supply has to be made available for various users. There are inequalities in access to safe drinking water in all over the world. Impure water is the root cause for many diseases especially in developing countries. Millions of people fall sick each year because of drinking contaminated water. In many regions of the world mostly in villages where Aloe-vera is easily available, can be used to filter turbid water. Polyaluminium Chloride is used worldwide in the developing countries to treat the water in the process of coagulation and flocculation. Continuous use of Polyaluminium Chloride in the treatment of water can cause many diseases. Therefore, it has become a need to treat the water by using some natural coagulants.

The main aim of the project was to reduce the turbidity by replacing polyaluminium Chloride with aloevera. The objective behind selecting aloevera was that alovera is a plant mostly found in villages.
