ICE Industrial Reverse Osmosis System for Cooling Tower Water System
The water that passes through the RO membrane is referred to as the "permeate" and the dissolved salts that are rejected by the RO membrane is referred to as the "concentrate". A properly run RO system can remove up to 99.5% of incoming dissolved salts and impurities.
Industrial reverse osmosis plant includes a multimedia pre-filter, water softener or anti-scalants dosing system, de-chlorination dosing system, reverse osmosis unit with semi-permeable membranes, and UV sterilizer or post chlorination as a post treatment. These RO machines apply the technology of reverse osmosis by transporting feed water through a multimedia pre-filter to remove particles that are larger than 10-micron. Then the water is injected by an anti-scalants chemical to control hardness fouling that may cause damage to the membranes of the RO machine. These pretreatment options have the capability of removing hardness, chlorine, odors, color, iron, and sulfur. The water then continues into the reverse osmosis unit where a high-pressure pump applies extreme pressure to the highly concentrated solution, separating the remaining salts, minerals, and impurities that the pre-filter cannot catch. Fresh, potable water comes out from the low-pressure end of the membrane while salts, minerals, and other impurities are discharged into a drain on the other end. Lastly, the water is passed through a UV sterilizer (or post chlorination) to kill any bacteria and microbes that still exist in the water.
In order to choose the correct RO product, the following information must be provided:
1.Flow rate (GPD, m3/day, etc.)
2.Feed water TDS and water analysis: this information is important to prevent membranes from fouling, as well as help us choose the correct pre-treatment.
3.Iron and manganese must be removed before the water enters reverse osmosis unit
4.TSS must be removed before entering the Industrial RO system
5.SDI must be less than 3
6.Water should be free from oil and grease
7.Chlorine must be removed
8.Available voltage, phase, and frequency (208, 460, 380, 415V)
9.Dimensions of projected area where Industrial RO System will be installed
Reverse Osmosis / RO is a technology used to remove dissolved solids and impurities from water using a semi-permeable RO membrane which allows the passage of water but leaves the majority of dissolved solids and other contaminants behind. The RO membranes require water to be under high pressure (greater than osmotic pressure) to do this
