Design and Performance Evaluation of Decentralized Wastewater Treatment and Reuse System for Urban and Rural places

Abstract

The increasing need of water and depleting availability of water resources pressed the research world look for an alternative solution by treating the wastewater discharged from domestic dwellings for secondary reuse. It has proved to be an effective way to overcome this problem. The improper functioning of centralized treatment systems and huge cost involved for the operation and maintenance paved a way for the Decentralized Wastewater Treatment Systems (DEWATS). In the present study, two treatment approaches were evaluated in detail. Constructed wetlands and MBBR, for a residential complex in Rural and Urban sectors respectively. The systems are designed with the help of quantifiable data including the population, area available and various chemical properties of the wastewater discharged. The performance of the systems were monitored for a period of time and showed a good quality water that can be used for secondary applications like toilet flushing or gardening.
