University reuses sewage as biogas using Hyacinths

A group of biotechnologists from Vignan University have developed a model for conversion of domestic sewage water into biogas and bio-manure.

Led by scientist M.S Shivakiran, Department of Biotechnology, VU, two students Manikanta and Ravichandra, the model has employed a method called ‘Phytoremediation’ through which aquatic plants like water hyacinth could be used to produce biogas.

Mr. Shivakiran said, about 400,000L of waste water was released from the university buildings into the open fields breeding waste weed and mosquitoes. The team decided to take up a project, “Cost effective method of wastewater treatment by phyto remediation with concurrent production of biogas and bio-manure.”
