Septic Tank Baffle System - An Effluent Filtering Device

The cost effective filtering device is a compact co-axial system of PVC pipes which allows out flow of treated waste water while retaining the solid waste allowing anaerobic decomposition of waste resulting cost saving of 30-40% over conventional septic tanks. The installation of the device does away with baffle walls and dividers.The Indian patent No. 218900 has been granted to this innovation. The project has also been supported under MVIF.
