Paper Details

Water is growingly becoming a sparse resource. About 35% reduction of water usage in residential unitscan be attained with simple technology if grey-water is recycled and reused in toilet flushing and irrigation andconstruction purposes. Also, it has been a vital technology in developing countries to treat and reuse industrial wastewater saving money on all levels; water-heavy-consumption-industry can reduce its consumption by 80% throughrecycling processes provide benefit after reasonable return of investment period. Large and medium-scale water usersneed to take measure to conserve it for an active demonstration of their concern about the global pollution andenvironmental problems. This paper presents the treatment methods for greywater. Technologies used for greywatertreatment are classified into natural, physical, chemical and biological systems or a combination of all these. Usage ofphysical processes solely as the main treatment method is insufficient for greywater treatment, chemical greywatertreatment processes are captivating for single household low-strength greywater treatment systems, as the irregularity inthe flow of the greywater did not affect their treatment performance. In Natural ways, constructed wetland can beregarded as the most environmental friendly and cost-effective technology for greywater treatment and reuses. Finally,greywater treatment methods mostly vary based on site conditions and the characteristics.
