250 LPH Commercial RO Plant :

  • Compact Design -Size of the RO plant is only 2.5 feet X 2.5 feet X 5 feet which will have the complete system of interconnecting pipe lines , pump, membrane control panel etc.
  • Its just connect and start use concept. Latest design, Latest Equipments used, High Durability.
  • No Antiscalent required like traditional old RO plants, High pressure Auto flushing takes care of the membrane thus eliminating anti-scalent dosing cost which in turn is a very huge savings on your recurring expenditure.
  • Online Volt meter, flow-meters, panel lights, push in starter switches etc helps the operation of the machine very easier.
  • Auto flush valve (auto timed) helps to double the life of the membrane.
  • Low pressure switch and tank full option can make the system fully automatic.
  • No Operator required as the plant can be made fully Automatic with level sensors.
  • Super space saver.

250 LPH commercial RO plant :


Cartridge filter is provided to remove suspended matter and guard against the entry of foreign material into the final treatment.


To overcome the Natural Osmotic Pressure a reverse thrust of high pressure is required to separate the Ions from water.

Depending upon the projection, an initial feed pressure is determined.

A Vertical Multi-Stage Centrifugal Pump is used for this application.


Production of low dissolved solids  content by reverse osmosis using state of the art TFC Membranes. The high dissolved  are separated into two streams. Product stream – with 2-3% of the feed salt will be collected. The second stream ( Reject stream ) of 97-98% more concentrated salt will be collected. Based on the feed conditions and controlling parameters a recovery ratio can be worked out from 60-75%


Membranes form the barrier for the ionic separation. This separates the water into two streams. A product stream with ionic impurities and a reject stream with high ionic impurities.The ratio of two streams depends upon the design and can be anywhere between 0.3 – 0.7. The membranes are sensitive to various types of fouling and scaling factors. Hence a proper pre-treatment is necessary. Polyamide thin composite membranes are used and is currently imported items.


The skid supports the reverse osmosis pressure vessel, membrane, control panel, pressure gauges and etc., The skid mounted design helps in assembling of components at the shop floor easier and much faster.

An isometric AutoCAD design is developed for SKID Fabrication for better space utilization and plant aesthetics.


To check the quality and monitor continuously, Online Conductivity Meter will be provided at the RO permeate water.


This is a separate unit out of the RO Machine which safe guards the machine and gives a longer durability to the RO machine – the raw water is fed to this system so that the color, turbidity and suspended impurities are removed, to certain extent and then water passes to the micron filter in the RO Machine. Certain bacteria and virus are also in-activated due to the activated carbon in this chamber.
