Abstract :
The laboratory scale greywater treatment unit was designed. The aim was to determine the effect of filter mediums on pH, temperature, total dissolved solids (TDS), electric conductivity (EC), dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), and turbidity of greywater. The indigenous materials such as burnt bricks (BB), sawdust (SD) and gravel of particle size 5mm were set at 1L/h flow rate. The results concluded that SD was effective to normalize the pH 10.2 to7.2 and eliminated the TSS up to 52.01%. It was effective in removal of TDS and decreasing EC. While gravel performed better for decreasing BOD, COD and increasing DO levels.
