reverse osmosis

The ultra-low pressure differential design of the BW-XFREC8040/BW-XFREC4040 membrane element allows the system to achieve better flow distribution, which means that in environments where biological contamination is more common, such as wastewater treatment, the water flow can be distributed more evenly among the components of the system. Can resist organic pollutants, good cleaning effect, low energy consumption, and has a high organic solute removal rate.

SW-HREC8040/SW-HREC4040 membrane can provide reliable and efficient technical solutions for industrial users to help solve difficult water treatment problems, such as wastewater reuse and (near) zero discharge and zero discharge, the SW-HREC8040/SW-HREC4040 membrane can condense the concentrated water TDS to > 70,000 ppm within the normal operating boundary conditions.

Product Overview

Ro reverse osmosis works by flowing water from low concentration to high concentration. Once the water is pressurized, it will flow from high concentration to low concentration, this is known as reverse osmosis: because RO membranes have pores one millionth the size of a human hair (0.0001 microns) , they are invisible to the naked eye, and bacteria and viruses are 5,000 times larger, only water molecules and some mineral ions can pass through, other impurities and heavy metals are discharged from the waste pipe. So Ro membrane also known as in vitro high-tech“Artificial kidney.”. At home and abroad, medical, military and civil fields, have adopted top-grade RO membrane for polymer filtration.

Main functions

When two types of water with different salts, such as a semi-permeable membrane, are separated, the water on the less salty side will penetrate through the membrane into the more salty water, and the salt content will not penetrate, thus, gradually the salt concentrations on both sides are fused until they are equal, a process called osmosis. However, this process takes a long time to complete. But if a pressure is applied to the side of water with a high salt content, the result can also make the above-mentioned infiltration stop. The pressure at this time is called osmotic pressure. If the pressure is increased, it can be made to permeate in the opposite direction, while the salt remains. Therefore, the reverse osmosis desalination principle, is in saline water (such as raw water) , to apply more pressure than the natural osmotic pressure, so that the osmosis in the opposite direction, the water molecules in the raw water pressure to the other side of the membrane, into clean water, thereby achieving the removal of impurities in water, salt.

Application Area

Seawater desalination, brackish water desalination, pure water and ultra-pure water preparation, bio-pharmaceutical water, industrial sewage treatment, municipal sewage treatment, food processing and household water purification and other fields. Technical features: explain in detail the unique technical characteristics and advantages of each product.

Technical characteristics

High-efficient desalination: Ro membrane can remove salt, heavy metals, organic matter and other dissolved matter in the water, desalination rate can reach 99.8% , the effluent quality is good.

Operation Stability: Ro membrane process has high mechanical strength and service life, can withstand the impact of chemical or biochemical, pH, temperature and other factors less affected 3. The effluent quality of RO membrane process is also relatively stable and less affected by external factors.

Flexible operation: Ro membrane process can be designed and adjusted according to different water quality and demand, can achieve different levels of purification and concentration.
