What is Reverse Osmosis (RO) Water?
Reverse Osmosis water was invited by the US Navy to remove the sodium from ocean water in order to have drinkable water on submarines. That RO system has been refined and enhanced to the systems we have today that are available to commercial and residential customers.
Reverse Osmosis Systems remove TDS from water using pressure through a membrane that separates the water into the concentrate (reject water) and permeate (product water). The systems operate in a pressure range from 200 psi to 1200 psi depending on the application. The higher the TDS, the more pressure is required to overcome osmotic pressure.
Our engineers can design reverse osmosis systems for any application. Because we custom design our systems for each individual project, we are not limited by flow rate, size, or customer specific requirements. Most reverse osmosis systems fall into three main categories; traditional, brackish, or desalination/frac water.
Traditional RO System
Traditional reverse osmosis systems operate with a feed of 200 psi to 400 psi. This means that a minimal amount of energy is used to pump the feed water through the membranes to overcome the osmotic pressure. The feed TDS levels are typically 100 ppm to 1,000 ppm. Traditional reverse osmosis systems have a configuration that includes a pre-filter, pvc header piping, plc controller, and fiberglass pressure vessels for the membrane housings. Options include stainless steel pressure vessels, stainless steel header piping, plc controller with remote monitoring, controller with touch panel display, design modifications for higher recovery rates, and other items depending on your application.

Brackish RO Systems
Brackish reverse osmosis systems tend to operate over 400 psi and require more energy as a higher pressure pump is necessary. Brackish water has higher total dissolved solids than water that is fed through a traditional reverse osmosis system. The feed TDS levels are typically 1,000 ppm to 5,000 ppm. Brackish reverse osmosis systems have a configuration that includes a pre-filter, pvc header piping, plc controller, and fiberglass pressure vessels for the membrane housings. Options include stainless steel pressure vessels, stainless steel header piping, plc controller with remote monitoring, controller with touch panel display, design modifications for higher recovery rates, and other equipment depending on your application.
Desalination / Frac Water Treatment
Desalination reverse osmosis systems operate at 800 psi to 1200 psi. At 800 psi and above, a special high-pressure pump is required. These pumps not only produce high pressure but need to be made out of special alloys. Because of the increased amount of energy that is required to overcome the osmotic pressure, energy recovery devices are typically used. The feed TDS levels for desalination/frac reverse osmosis systems are typically 5,000 ppm to 40,000 ppm. Because of the high levels of TDS, the piping is made out of stainless steel or a variety of special alloys. Standard components are a plc controller with remote monitoring, touch panel display, and fiberglass pressure vessels.
