Author(s): Zeynush amil

Water contamination is a serious international issue various technologically advanced treatment methodologies for example activated sludge process, membrane bioreactor, trickling filter, rotating biological contractor and oxidation ditch are widely studied, well documented and adopted in practice. however, attention to promising low- investment-cost technologies such as slow sand filtration techniques was humdinger miniscule. (at a flow rate of 0.1–0.2 m3/h) is quite effective water treatment technology. It is also efficient in removing coliform microorganisms such as Cryptosporidium, E. coli and bacteriophage from water/wastewater. Apart from reduction of pathogenic load which is ascribed to the biological processes. SSF can efficiently remove turbidity, suspended solids and toxic metals in treated water. The SSF treated effluent conforms to the discharge standards for potable (drinking) and non- potable (such as irrigation) uses.
