Design and Performance of Grey Water Treatment Plant

Advanced Oxidation Processes (AOPs), Moving Bed Biofilm Reactor (MBBR) systems, and Constructed Wetlands (CWs) to enhance efficiency of organic and inorganic pollutant removal. MBBR system consists of an aeration tank it is similar to a activated sludge tank with plastic media which surface biofilm can grow. Initially grey water feed to AOP system then MBBR and finally pass through wetland construction. AOP and MBBR is a recent and beneficial biofilm technology which has many properties which includes anti-load ability, High treatment efficiency. AOP and MBBR technology became more popular and widely utilized worldwide due to fact that need for clean water keeps to rapidly increase with increase in population of the world grows year by year. Greywater from Bathroom Water used in hand washing and bathing generates around 50-60% of total greywater and is considered to be the least contaminated type of greywater. Greywater is specifically washing water like bath, dish and laundry water excluding toilet wastes and free of garbage-grinder residues. Gray water shows the Initial characteristics TDS, pH and SS are 900 mg/l, 8.5 and 413 mg/l. After treating with AOP shows the TDS, pH and SS are 750 mg/l, 8.3 and 327 mg/l, after MBBR treatment TDS, pH and SS are 400 mg/l, 8.3 and 104 mg/l and Final wet land construction treatment TDS, pH and SS are 118 mg/l, 8.3 and 50 mg/l.
