Overview
Ecosoft industrial reverse osmosis systems are used for demi-
neralizing water in industrial, municipal, commercial applications.
Ecosoft RO system can be used to demineralize low to medium salinity
feed water. All parts of the system that are in contact with water have
the necessary certifications for use in food/drinking water applications.
Reverse osmosis system operates as follows. First, raw water is
fed through sediment prefilters to remove particles. The water may
be dosed with antiscalant or other RO chemicals with a dosing pump
at this point. Then, high pressure pump feeds the water into the
membrane module or membrane array, in which feed stream
undergoes separation process and splits into purified and
concentrated streams. Part of the concentrated stream is discharged
to drain, and the rest is fed back to suction end of the high pressure
pump, referred to as concentrate recycle. Drain line is fitted with
drain flow control that limits rate of concentrate discharge and
determines the ratio of purified water (permeate) to waste water
(concentrate). The ratio is called recovery. Recycle line is fitted with
recycle flow control that limits recycle flow rate and creates working
pressure in the membrane array. Rate of permeate production is
proportional to the pressure in the membrane modules.
Commissioning and configuring the RO system includes carefully
adjusting the flow controls to the right settings.
