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.

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
Specifically membranes that are used for 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.
Hi, im a student engineer currently trying to figure out if there are any techniques of adding chemicals to a waste water plant which contain lots of salts produced from concrete manufaction..... the water is currently to salty to discharge to the stormwater system and needs to be adjusted before it can be discharged, are there any chemical ways to remove salts either than filtrations, reverse osmosis etc... thanks

How Water Purification Is Performed With Reverse Osmosis Water ...
Reverse osmosis water treatment or RO, as it’s commonly called, uses water purification in an industrial setting for the purpose of human consumption. With this system, mineral salts, pesticides and bacteria can be removed from the water.
This system has been modernized with upgraded technologies in water treatment. It has also added an advantage to the original reverse osmosis water treatment process. The advantage of the reverse osmosis process water treatment is that less energy is used and there is not a lot of water waste. This also helps to decrease cost.
Saltwater and brackish water can also benefit from using reverse osmosis water treatment. It is also used for water production which has a high purity level. Most of the minerals and other polluted elements that are found in the water disappear. The feed water is a stream of water that joins the reverse osmosis water treatment process and pressure is exerted on this stream.
...Things you need to know about Reverse Osmosis water treatment plant
Processes of filtration and purification is very important not only in connection with muddy water up to the stream can contain multiple clear microorganisms harmful to our bodies. When the invention of the purification of drinking water should not worry about the metals, germs, bacteria, fungi and protozoa present in our waters. The new products are released every day, but most of them tried the old relay system. There are different types of drinking water purifier, and some are based on filtering and some other disinfectants available, such as chlorine, ozone or iodine. In this article I will concentrate on a method of filtration, reverse osmosis. R / O (mutation test reverse osmosis) is a filtering method that more and more people are using. This method of filtering produces very pure water. They us a complex process of filtration of water, using multi-stage process to clean and that is why they are called "ultra purification" filters. For those who want a simple under sink or maybe a water purifier for the home, these filters are perfect, unless you have a po 'd'acqua. In this case, you should try something different. More on this later. 2nd The second step is when the water pressure is very high that only through the membrane allows water molecule impurities and not to move. The pure water within a holding tank and the impurities washed away the waste water container. You must use a holding tank because the R / O filter is a slow process and it will take some 'time to finish. For those who want a simple under sink or maybe a water purifier for the home, these filters are perfect, unless you have a po 'd'acqua. The first step is the filter is to remove remaining large particles. The pure water within a holding tank and the impurities washed away the waste water container. The system can not protect against micro-organisms in water, as I mentioned earlier, the process of filtration is a slow process. Only about 15 percent of water that you use the turn of drinking water quality.
