Alternate treatement of water for reverse osmosis

Yes its called good old fashioned wet lands,that will do the trick. But first you might want to run the water through a primary and secondary waste water treatment

Sorry, soapy water won't cut it; and in fact will probably make things worse. Soap won't get rid of hard water scaling - it'll just scum it up. Soap won't get rid of any mold or fungi - it'll actually feed them. Use a commercially available RO membrane cleaning solution. They have to meet government requirements.

Which is cheaper in term of energy cost? Seawater desalination or waste water treatment by RO?
And which one is more environmentally friendly?

Note:
With a reference plz
RO= is reverse osmosis

reverse osmosis is only used as a final stage in waste water treatment so its not a fair comparison. you would have to add in the pumping and agitating energy for the sewage works.

desalination by reverse osmosis takes up less room, but more energy than for the final stage 'polishing' of waste effluent. in fact it is most common to use brackish water where possible, to make the process easier and reduce time between back washes. also you have to add in the energy used to pump the brine back out to sea a good way, you cant just discharge it back into the estuary..

either are only as environmentally friendly as the energy source used.

i would like to design a reverse osmosis system, i need a output of 800 to 1500 GPD. Kindly guide me how to select a pump, membrane, pre-treatments, etc.,. my TDS is around 1500PPM and hardness is 870ppm. ph is 6.3.

Reverse Os can be obtained just like de ionzing water,they make systems just for that pupose for portable auto wash systems.there are several web sites for water control systems,all price ranges.i would start with a simple search of ,portable wash systems or power wash,pressure wash you ll come across links in there that can help you buy or build your own.they even have plans for using a basic water heater,such as the type in a household use.depends what your needs require.hope this was helpfull i have to treat water before i clean certain surfaces.
