Reverse Osmosis

A Reverse Osmosis System is a Cross Flow Water Purification Process.

Raw Water is forced into the membrane housing under pressure – as high as 800 PSI. The water is forced through the membrane and enters the center tube without most of it’s contaminants which are discharged to drain.

Pretreatment which removes particles and objectionable dissolved minerals is required to maintain the flow and quality of water in reverse osmosis.

We offer Packaged Reverse Osmosis Systems :

  • Small Scale
  •  Large Scale
  • With Pretreatment Skid

When interested in an RO, it’s good to have in mind how much water you need per day – per week etc. as well as knowing what your maximum hourly usage of the water will be.
