REVERSE OSMOSIS
Reverse Osmosis is a membrane separation process wherein purified water is extracted by using synthetic membranes which are permeable to water molecules but relatively non-permeable to contaminants. The raw water stream is first pressurized to reverse the natural osmosis process that occurs across the semi-permeable membranes.
The ROS-100 System is a reverse osmosis module designed for large industrial applications. Each ROS module utilizes 8 inch diameter spiral wound membranes, housed in fiberglass vessels producing a capacity of 100 G.P.M. The modular design allows for easy expansion.
The ROS-100 is a free standing system designed and engineered for ease of maintenance and operation. Solid state controls provide continuous monitoring of all critical parameters in addition the system will automatically stop the system when conditions are not within preset limits, i.e. low suction pressure, high product conductivity. Instrumentation includes liquid-filled pressure gauges; product and concentrate flow meters; and a conductivity meter to measure product water quality.
PUMP PACKAGES
Pumps are selected according to the number of ROS-100 modules. The pumps are stainless steel centrifugal type with integral 3- phase, 60hz or 50hz, (optional) TEFC (totally enclosed fan cooled optional) motors.
