RO Systems
Introduction
INDROMATIC desalination system uses the latest reverse osmosis technology to remove most of the dissolved solids from saline/brackish waters.
Product Description
The heart of the INDROMATIC unit is the reverse osmosis membrane that is fitted inside the pressure vessels, selected to yield the desired quality and quantity of product water. Feed water to the unit is pressurised at the first stage by means of a booster pump. Feed water, then passes through a cartridge filter for removal of suspended particles, which would otherwise foul the RO membranes and decrease its productive life. The pre-filter unit consists of a replaceable filter cartridge, fitted inside filter housing.
Filtered water is then pressurised by means of a high pressure multistage centrifugal pump, with chemically inert wetted parts, driven by a three phase electric motor, working on three phase electric supply. The pump is protected from dry running and excessive pressure by means of pressure switches.
The pressurised water then enters the RO Membranes, wherein it is divided into the "product water" and "reject water" streams. The reject water stream is further bifurcated into two streams through two control valves. One reject stream is recycled back to the suction side of the pump and another stream is drained. The control valves are provided in the reject water line for regulating the extent of recovery of the system. The product water stream, which is discharged at low pressure passes through a conductivity sensor. The quality of product is indicated by means of the conductivity parameter on the display. The product flow rate is measured by the flow sensor and displayed on the control panel. The complete system is mounted on mild steel frame, with the motor being bolted to the bottom of the frame work.
The power supply switch for the motor as well as instruments is mounted on the control panel, is properly insulated; PVC-sheathed wiring is provided for external and internal power connections.
The cartridge filter, the RO pressure vessels, and the various instruments are all clamped to the structural framework. All internal and external water connections are provided by means of plastic pipe /tubing suitable for high pressure operation and for drinking water applications, thus, making INDROMATIC a self-contained unit.
INDROMATIC is provided with the following external connections for field installation:
- Feed water pipe/tubing to be connected to the source of water
- Product water pipe/tubing
- Reject water pipe/tubing
- Power supply cable lead, to be connected to the main power supply
