Development of Portable Grey Water Purification System for Urban Housing

Rapid urbanization and industrial development have led to a significant increase in wastewater generation, creating a need for efficient and sustainable treatment technologies. Conventional wastewater treatment systems require large land areas, multiple treatment units, and complex operation. The Sequencing Batch Reactor (SBR) technology is an advanced biological treatment process that overcomes many limitations of conventional activated sludge systems. In SBR technology, all treatment processes such as filling, aeration, reaction, settling, and decanting are carried out sequentially in a single reactor tank, eliminating the need for separate clarifiers and reducing space requirements. This paper studies the application of SBR technology for wastewater treatment with respect to its working principle, process efficiency, and operational flexibility. The system effectively removes BOD, COD, suspended solids, and nutrients like nitrogen and phosphorus. Due to its batch operation and automated control, SBR can handle fluctuating influent flow and load conditions efficiently. The study concludes that SBR technology is a cost-effective, compact, and environmentally sustainable solution for modern wastewater treatment systems.
