The quite effective water treatment technology is also efficient in removing coliform microbes such as E. coli. Water pollution 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. And bacteria from water/wastewater Apart from reduction of pathogenic load which is ascribed to 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) users realize how hard it is to clean.
