An approach to develop a cost-effective gray water treatment mechanism; A case of KDU canal

Grey water has become major problem worldwide. Also, it is the same for the KDU. There is a canal carrying grey water through the KDU. This has become a problem for years. There have been temporary solutions such as cleaning work for short-term periods. We focus our research area to give sustainable solutions to this problem. We did a feasibility study whether we will be able to give a sustainable solution to this problem. We investigated the grey water, the flow of the KDU canal where is water coming to the KDU canal and the parameters of the KDU canal grey water. we looked for viable filtration systems available for cleaning the grey water in the KDU. The best solution we got was the sand filter and activated carbon filter which utilizes the gravitation filtration method incorporated with traditional filtration traditional methods such as Strychnos potatorum seeds. Powered and whole seeds are utilized in the filtration system as a natural coagulant. Since it has proven to have coagulant properties. Using Strychnos potatorum seeds is an economical and eco- friendly method. Since if we utilize another method to clean the grey water. KDU must bear the initial cost as well as the maintenance cost. Strychnos potatorum seeds are a cost-effective water-cleaning method. Strychnos potatorum seeds can be obtained from the environment Strychnos potatorum seeds span expire it can be disposed to the environment, it will decompose with time. The final water outcome water would be utilized for irrigation purposes or recreational uses.
