Development of Equalization Tank for flow rate attenuation in small scale Wastewater Treatment System

Abstract

A prototype equalization tank was developed for the treatment of 250 litres of domestic waste water per hour. The tank was fabricated from mild steel plate with pipe network, the lift pump and air blower. Five samples run of wastewater flow was tested with the tank for 150, 175, 200, and 225 litres of wastewater. The equipment was found to be effective at wastewater inpt flow volume of 175 liters per hour. However the highest recovery was obtained at the input rate of 200 liters per hour of the wastewater, he equipment was not performing optimally at this recovery quantity. The study inferred that equalization becomes essential to obtain proper performance of the treatment plant
