Water is purified by three successive filters 2, 3, 4, and valves 101, 26 and pump 32 enable water to be delivered to common outlet 7 from the downstream side of any selected filter. Thus water suitable for drinking is filtered by all three filters, while washing water is less purified....

Hence, increasing awareness has been growing rapidly worldwide and one of the offshoots is the treatment and removal of this toxic material from such effluents to a permissible limit before discharging them into streams and rivers. For water purification treatment various technologies are in use. ...
The efficiency of water purification by two different mollusks was determined under same algae biomass in 24 hours.The results indicated that there were twice higher elimination efficiency of suspended substances in Cristaria plicata than that in Bithynia fuchsiana,but Bithynia fuchsiana had as twice...
Four wetland plant species(Acorus calamus,Typha orientalis,Lemna minor,Ceratophyllum demersum) were grown to compare the purification efficiency of wetland plant species alone and in combination on two eutrophic water bodies,high concentration sewage(influent) and low concentration sewage(effluent) in a...
The threshold concentration of O3 for continuous human exposure is 0.075 μL/L (US Environmental Protection Agency, 2008). Although there are many studies on the removal of pesticides using O3 for water purifications in waste water, there are several reports on the use of O3 to remove ...
