how to convert seawater into drinking water

Also, the typical removal shade using of biologically processes obtained only 70%, which are suggested possibility of using nanofiltration for post processing treatment. The high quality of the dealt with wastewater can be improved if the sophisticated processes are combined with them. The use of ultrafiltration process could not dramatically decrease the COD of the physicochemical treated water. However, making use of nanofiltration membrane layers, the COD concentration can dramatically be lowered in such manner ins which penetrate of the nanofiltration membrane could be reused in the market. The combination of the physicochemical treatment as well as the nanofiltration brings about a COD removal of practically 100%. Likewise, a comparison in between the role of the activated sludge treated wastewater combined with nanofiltration and ozonation procedures have actually been studied. It is generally either Phosphorous or Ammoniacal Nitrogen or both that the E. A. want minimized. Tertiary treatment involves this process. If Phosphorus is the offender, after that a continual dosing system to remove it is the tertiary treatment. If Ammoniacal Nitrogen is the problem, after that the sewage treatment plant process must entail a nitrifying and then de-nitrification phase to transform the ammoniacal nitrogen to Nitrogen gas that harmlessly enters the ambience.
