Investigation of Recyclability of Domestic Gray Water
Abstract
It is aimed to treat and reuse gray water in order to meet the increased water requirements as a result of the decrease in water resources. Purifying and recycling gray water with the aim of protecting drinking water is an alternative resource. Gray water from showers, bathroom and kitchen sinks, washing machines and dishwashers constitute a large part of domestic wastewater. Gray water contains a low amount of total pollutant load. Gray waters, which include waste water other than toilets, constitute 55-80% of the total domestic water use.
The gray water used in this study was obtained from a residence of 20-24 people consisting of 6 flats in Kocaeli province, Izmit district. Among the various gray water recycling treatment technologies, SBR (Sequential Batch Reactor) is an effective treatment technique for reducing dissolved suspended solids and nutrient removal from gray water. A lab-scale SBR was designed as a pilot plant to treat gray water. Water samples were collected at 1-day and 2.5-day hydraulic reaction times (HRT). In the results obtained in 1 day of HRT; avg. pH value 7.32, avg. EC value 586.8 µS/cm, avg. DO value 3.30 mg/L, avg. turbidity value of 7.39 NTU and avg. turbidity removal efficiency 99%, avg. TSS value of 6.92 mg/L and avg. TSS removal efficiency 98%, avg. phosphorus value is 7.51 mg/L and avg. phosphorus removal efficiency 84%, avg. nitrogen value is 15.92 mg/L and avg. nitrogen removal efficiency 59% and avg. COD value is 569 mg/L and avg. removal efficiency was measured as 69%. In the results obtained in 2.5 days of HRT; avg. pH value 7.76, avg. EC value 574.6 µS/cm, avg. DO value 5.07 mg/L, avg. turbidity value of 4.34 NTU and avg. turbidity removal efficiency 99%, avg. TSS value of 4.72 mg/L and avg. TSS removal efficiency 98%, avg. phosphorus value is 3.79 mg/L and avg. phosphorus removal efficiency 89%, avg. nitrogen value 13.02 mg/L and avg. nitrogen removal efficiency 54% and avg. COD value is 368 mg/L and avg. the removal efficiency was measured as 70%.
