A LABORATORY SCALE ANALYSIS OFGREYWATER USING DRAWER COMPACTED SAND FILTER

Water is an important natural resource to maintain human and animal life. Due to rapid industrialization, development and increasing population there is an increase in demand of water. So we need to search for alternatives to reduce the consumption of freshwater. One of such alternative is greywater treatment. Sand filtration has been considered as one of the effective and economical methods for water and wastewater treatment. One of such sand filtration technique is Drawer Compacted Sand Filter (DCSF), which is a modified design for sand filter. This paper presents the performance analysis of Drawer Compacted Sand Filter(DCSF), carried out on the basis of its first cycle. It was found that DCSF is efficient in removal of COD, TSS and turbidity with removal percentage of 95.83%, 80.76% and 89.71% respectively. It is easy to maintain, flexible, requires less area, effective and less expensive.
