2.1. OVERVIEW
Ecosoft brackish water reverse osmosis systems are used for demineralizing water in industrial,
municipal, commercial applications. Ecosoft BW RO system can be used to demineralize low to
medium salinity feed water. System components comprise stainless steel skid, prefilter housing,
high pressure pump, pressure vessels with membranes, electrical panel, process controller, and the
necessary valves and instruments.
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety. Children should be supervised to ensure that they do
not play with the appliance.
Ecosoft RO systems operate as follows.
Raw water is fed through sediment prefilter in order to remove particles. If raw water is treated
with antiscalant or other RO chemicals, the prefilter housing ensures better mixing.
Then, high pressure pump feeds the water into the membrane module or membrane array, in
which feed water undergoes separation process and splits into permeate and concentrate streams.
Permeate (purified water) goes to the permeate outlet and is collected in water tank. Permeate
line is also fitted with a pressure switch to halt the unit if significant pressure builds in permeate
line indicating a full pressurized tank or pipeline shutoff.
Float switch has to be put inside an ambient pressure tank (if used) to start and stop the unit
depending on the level of permeate in the tank.
Part of the concentrate stream is discharged to drain via drain rotameter. The rest goes back to
the suction end of the high pressure pump via recycle rotameter.
Flow rates of drained and recycled concentrate have to be regulated to specified ranges in the
Technical specifications with the regulating valves built in the rotameters.
When service is interrupted by float switch or pressure switch signal, the system runs a forward
flush (membrane rinse) cycle, then switches to standby. The controller receives temperature and
conductivity of permeate, permeate level, pressure switch statuses, and external inhibition signals.
