INSTALLER AND USER GUIDE FOR REVERSE OSMOSIS SYSTEM ECOSOFT ROBUST 1000, ROBUST 3000
1. APPLICATION
Reverse osmosis process is one of the most advanced technologies of water puricaon. Reverse
osmosis lter uses a special semipermeable membrane similar in its structure and properes to the
membrane of a living cell. It can be conceived of as having ny pores that are 200 mes smaller
than viruses and 4000 mes smaller than most bacteria. The principle of reverse osmosis water pu-
ricaon is modelled aer living cell’s natural water cycle. It allows purifying drinking water from all
harmful impuries, including nitrates and viruses (see Figure 1 below). Only molecules of a certain
size can penetrate through cellular membrane.
Ecoso RObust is a high recovery direct ow operaon capable reverse osmosis system. The system
can be equipped with a pressure tank for increasing puried water ow rate, and its mulstage
design allows obtaining a high recovery up to 50%.
The system is tapped in water mains using feed adapter and feed valve. Tube is run from feed valve
to the inlet port in system’s port rack (labeled). The port rack also includes connecon ports for the
drain, pressure tank 6 (if used), and puried water faucet 1 or puried water pipe. Feed water rst
undergoes pre-ltraon in the sediment and carbon pre-lters where it is stripped of suspended
parcles (rust, sand, hemp strands etc.), organic color and chlorine compounds. Pressure gauge no.
