Abstract:

The Greywater Treatment System was fabricated on laboratory scale. The burnt bricks, gravel and sawdust were used as filter medium with particle size of 1mm.The flow rate from sample holding tank to collection tank was 0.6L/min. The attempt was made to analyze the effects of filter mediums on decontamination of greywater samples. The experimental results showed that the burnt bricks reduced the mean total dissolved solids (TDS) 34.7% ± 2.67. The gravel exhibited the better results in mean turbidity removal 83.90% ± 1.89, reduced the mean BOD 19% ± 3.4 and mean COD 50.1± 4.1 improved the mean DO level twice compared to other filter mediums. The sawdust was effective to normalize the mean pH 7.0 ± 0.37, mean temperature 14.40 C ± 2.13, and mean total suspended solids (TSS) 51.46% ± 3.2.
