Inlet Water here may refer to brackish or sea water
The inlet water is kept moving over the membrane to prevent a high local ion concentration (which would impede the process). The flow flushes the ions and other non permeable contamination away, this flow with slightly higher ion concentration is then rejected

Does anyone know how much it costs to run a reverse osmosis plant?
Are you asking about operating costs or capital costs??
It depends on the size ofcourse!! But portable RO plants are available commercially for use in remote locations. So operating it is 'affordable'.
the input is a ground water and not sea water, for moderate salinity levels the processes required for maintenance (chemcial, cleaining and replacing mesh / fileters etc) please quote desing guides / papers / sources of knowledge

Is it safe to use Reverse Osmosis return water to water lawn and plants?
A lot of water goes back to a drain pipe. Im wandering if I could catch it and use it to water my back yard, instead dumping it back to a drain pipe?
ok
My under the sink RO system has a return line that is connected to a drain pipe of the sink. Is it OK to redirect that line and save that water for plants?
I don know if I can be any clearer.
Thnx
Yes, in most cases the "return" water is not significantly different than the regular tap water.
Israeli researchers scale up reverse osmosis model for ...
Researchers at the Ben-Gurion University of the Negev are using grants from the NATO Science for Peace program and the Middle East Desalination Research Center (MEDRC) to scale up a method to achieve high recoveries in desalination by reverse osmosis (RO). Jack Gilron, senior scientist and adjunct professor in the environmental engineering unit of the Zuckerberg Institute for Water Research (ZIWR), and Eli Korin, professor in the department of chemical engineering, have developed a method to exploit the finite kinetics of membrane fouling processes by periodically changing the conditions leading to membrane fouling before it can occur. In collaboration with colleagues from the University of Colorado and the Hashemite University of Jordan, the group will develop the technology and set up pilot facilities to produce approximately 120 m3/day each at desalination sites in Israel and in Jordan. “The process will be tuned to reduce brine volumes to 50% to 33% of those generated in conventional RO,” Gilron explains. “This greatly reduces the environmental burden and improves the economics of the inland desalination process.” BGN Technologies, Ben-Gurion University’s tech transfer company, and the Ashkelon Technology Incubator (ATI) Cleantech Group have formed a start-up company, Reverse Osmosis Technologies, to commercialize the technology, which has already attracted an initial investor.

It’s mind-boggling. Just 5 weeks ago, I was first introduced to Deepinder Mohan, CEO of the R/O manufacturing company Environment Planning Group Limited , over e-mail. Tomorrow, I will be spending the entire day with him face-to-face, experiencing first-hand the transformation of an opportunity–to bring clean drinking water to a needy community in India–into reality.
In convenient bullet-form, here is what has happened in the past eight days (since the last post):
Deepinder Commits to Visit : after reading the previous blog post, Deepinder booked his plane and train rides to travel from Ahmedabad to Gadag (16 hours one-way!). Both a huge financial and time expense, Deepinder decided to take the leap of a faith (financial funding was not yet 100% secured), fully inspired and committed to see our work to its completion. Financial Funding Secured! : my personal network stepped-up big time - and it happened to be my family–my parents–whom...
