I assume you mean 5 cubic meters? That is a small R/O plant and a google search will get you many manufacturers. Expect a 50% rejection rate, meaning if your total volume of water to be desalted is 5 M3, then you will get 2.5M3 of desalted water and 2.5M3 of double the salinity water. If you go to a membrane manufacturer's website, they will let you download a software which will advise you on system design, if you have an accurate water analysis.
Some companies I know who do a decent job:
Applied Membranes, San Marcos, CA
Water Equipment Technologies (somewhere in FL)
Osmonics (part of GE Water Group)
Hope this helps.
