Performance Appraisal of Two-stage On-site Domestic Wastewater Treatment System under Ambient Environment
Abstract: AbstractThe rapid growth in population has rendered the centralized sewerage systems a non-realistic option in sparsely populated areas. Consequently, an on-site wastewater treatment system (OWTS) is a viable alternative and cost-effective solution of sewerage system. Septic tanks with soil absorption systems are a simple mean of onsite treatment of the domestic wastewater. However septic tanks have low treatment efficiency along with several technical and constructional drawbacks. In order to improve …
