Removal of coliforms from waste water using biochar

Waste water contains coliforms and many pathogens which is harmful to the humans and other living organisms. Various agroindustry by-products such as peanut shell, corn cob, wheat husk, bagasse, sawdust, rice straw, etc. are generated in huge amount. These agroindustry by-products are just thrown or get piled up. Hence, they can be used for the environmental clean-up purposes which will helpful globally. These can be used for the removal of coliforms from waste water due to their adsorption capacity. The study here reports the use of bagasse in removal of coliforms from waste water by most probable number method. About 72 and 78 % removal of coliforms was observed in presumptive and confirmatory tests of most probable number respectively. This will help in the treatment of waste water which is very essential. This use of bagasse based biochar technology for the removal of coliforms from waste water is very eco-friendly and cheap.
