Rapid sand filters are very common in all conventional water treatment plants. Capping of existing rapid can be the promising method improving performance filters. is process which upper bed layer few cm replaced with capping material. However, this technique limited India due to unavailability filter materials apart from sand. Some suitable for anthracite coal, PVC granules, bituminous broken ...

The ability of using aluminum filings which is locally solid waste was tested as a mono media in gravity rapid filter. present study conducted to evaluate the effect variation influent water turbidity (10, 20and 30 NTU); flow rate(30, 40, and 60 l/hr) bed height (30and60)cm on performance filter for 5 hours run time compare it with conventional sand results indicated that showed better than rem...

The removal of conifers through commercial timber harvesting has been successful in restoring aspen, however many aspen stands are located near streams, and there are concerns about potential aquatic ecosystem impairment. We examined the effects of management-scale conifer removal from aspen stands located adjacent to streams on water quality, solar radiation, canopy cover, temperature, aquatic...

Waste-tire-derived crumb rubber was utilized as filter media to develop an efficient filter for ballast water treatment. In this study, the effects of coagulation, pressure filtration and dual-media (gravity) filtration on the performance of the crumb rubber filtration were investigated. The removal efficiencies of turbidity, phytoplankton and zooplankton, and head loss development were monitor...
