reverse osmosis

Reverse osmosis separation technology is used to remove dissolved impurities from water through the use of a semi-permeable membrane. RO technology involves the reversal of flow through a membrane from a high salinity, or concentrated solution to the high purity, or "permeate", stream on the opposite side of the membrane. Pressure is used as the driving force for the separation. The applied pressure (P) must be in excess of the osmotic pressure of the dissolved contaminants to allow flow across the membrane.

Spiral wound RO membrane elements operate installed in pressure vessels. A pressure vessel usually contains from one to six elements connected in series. An RO system can be configured to have a single pressure vessel (small systems) or a number of pressure vessels connected in parallel (array) or in series (stage).

In a parallel array, all pressure vessels receive a similar flow of feed water and operate at the same recovery rate. The recovery rate depends on the number of membranes inside the pressure vessel. Each membrane is limited to a maximum 10 percent recovery. Therefore a pressure vessel containing 6 membranes should not exceed 60% recovery. In order to design RO system to operate at higher recovery rate, the waste water from an array (approximately 50% of the initial feed flow) is fed to another array, in series.

Reverse osmosis (RO), also known as hyper filtration, is used by our Commercial & Industrial Brackish Water & Seawater Reverse Osmosis Systems to purify water by removing salts and other impurities. It is also capable of rejecting bacteria, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 Daltons.

Hydrocompus Technologies Inc manufactures a full line of seawater desalination systems designed for heavy or continuous duty service in the marine applications where quality and dependable performance are keys. Our standard Brackish Water Reverse Osmosis systems are available with capacities ranging from 250 GPD to 500,000 GPD, and our standard Seawater Reverse Osmosis systems or water makers or RO desalination systems are available with capacities ranging from 380 GPD to 180,000 GPD. Hydrocompus is also capable of manufacturing custom built Reverse Osmosis plants.

All Series systems use state-of-art designs and materials for superior performance and life. We have many years of successful experience in seawater systems to produce drinking water for hotels, resorts and drilling platforms. We design and build standard or customized commercial, industrial and seawater desalination reverse osmosis systems for multiple applications.

Applications include:

Hotel/Resort Drinking Water

Municipal

Industrial

Irrigation/Farming

Offshore Platforms

Remote Islands

Military Facilities

Municipalities and industrial facilities are able to use RO permeate as a consistently pure drinking water supply and to transform drinking water to high purity water for industrial use at microelectronics, food and beverage, power, marine and pharmaceutical facilities.
