For wastewater treatment, reverse osmosis plant suppliers suggest RO technology to the industries to remove larger particles from potable water. This water purification technology is like ultra-filtration process. However, in RO process, an applied pressure is used to overcome osmotic pressure. It is a colligative property that is driven by chemical potential. With the help of Reverse Osmosis treatment, industrialists can remove several types of ions and molecules from solutions, including bacteria. This treatment is feasible for both industrial and potable-water production purposes.
When the technology is in use, solute is kept on the membrane’s pressurized side and the pure solvent passes through it. The membrane “selectively” lets smaller component solutions to flow freely without enabling the large molecules or ions through the pores.
While forcing water through a membrane (which is semi-permeable), solution is pressurized by a pump, which will allow water and other molecules having low molecular weight to pass through micro-pores present in the membrane. Most RO installations use a cross-flow to let the membrane to clean itself without rest. When the fluid passes through the membrane, the rejected particles are swept away from the membrane.
Reverse Osmosis in industries is usually operated at pressures between 100 psig-1000 psig. The pressure choice relies on the membranes chosen and the quality of water treated. Most of the time, all commercial and industrial applications apply multiple membranes in series. Treated water can pass through additional membrane modules from first stage to achieve higher levels of treatment for the finished water.
Where RO systems are installed and used?
Reverse Osmosis systems are applied in –
- Boiler feed-water treatment – Here RO system is used for reducing solid particles and content of water before passing it into boilers for power generation.
- Pharmaceutical – Pharma centers use high grade of water to prepare drugs.
- Food and beverage – RO system is used for both solids and liquids in food and beverages industry.
- Metal industry – Metal industry uses RO system for metal finishing operations, including distinct types of copper, nickel, and zinc electroplating.
More industries are adopting Reverse Osmosis technology rapidly and power generation industry is among them. Power producing companies are applying RO system for purifying boiler feed water, makeup water, and zero-liquid discharge applications.
If you need a RO system for your space, you can get in touch with Reverse Osmosis plant suppliers. Most suppliers are providing best guidelines to their customers to use their plants and systems efficiently.
