Principle, Application and Examples of Reverse Osmosis

Reverse osmosis system is the original water through the fine filter, granular activated carbon filter, compressed activated carbon filter, and then through the pump pressure, the use of pore size 1/10000μm (equivalent to the size of 1/6000 of E. coli, 1/300of virus) reverse osmosis membrane (RO membrane), so that the higher concentration of water into low concentrations of water, while industrial pollutants, heavy metals, bacteria, viruses and other impurities mixed with water in full isolation, so as to achieve the prescribed physical and chemical Indicators and health standards, the output to the clear to pure water, the human body is the best choice for timely replenishment of high-quality water. RO reverse osmosis technology for the production of water purity is the human master of all water technology, the highest, clean Degrees to almost 100%. Reverse osmosis membrane is the key equipment of reverse osmosis system, the system for a long time continuous operation, the water will continue to precipitate calcium and magnesium ions in the surface of the reverse osmosis membrane attached to the formation of fouling blocking membrane hole, this will affect the reverse osmosis system effluent efficiency, Damage to the reverse osmosis membrane. As the reverse osmosis membrane is more expensive, so the system is running, to add a dosing system, adding in the water reverse osmosis scale inhibitor, delaying the precipitation of calcium and magnesium ions and membrane fouling.

Features of reverse osmosis

The reverse osmosis scale inhibitor is specially designed for reverse osmosis (RO) system and nanofiltration (NF) and ultrafiltration (UF) system scale inhibitor, can prevent surface scaling, can improve water production and water quality, reduce Operating costs.

It can effectively inhibit the polymerization and deposition of silicon, the concentration of silicon dioxide on the side of concentrated silica (SiO2), the concentration of silicon dioxide (SiO2) and so on. The concentration of up to 290 ppm; can be used for reverse osmosis CA and TFC membrane, nanofiltration membrane and ultrafiltration membrane; excellent solubility and stability; PH value of 5-10 in the water are valid.

Reverse osmosis pharmaceutical basic role

1, Network and solubilization: reverse osmosis scale inhibitor dissolved in water ionization occurs, the formation of negatively charged molecular chain, which forms soluble and soluble Ca2 + complexes or chelates, so that the inorganic salt solubility Increase, play a role in scale inhibition.

2, The role of lattice distortion: the reverse osmosis inhibitor molecules in some of the functional groups in the inorganic salt crystal nuclei or microcrystals, occupy a certain position, hinder and destroy the normal growth of inorganic salt crystals, slowing the crystal growth Rate, thereby reducing the formation of salt scale;

3, The role of electrostatic repulsion: reverse osmosis scale inhibitor dissolved in water after the adsorption of inorganic salts on the microcrystalline, so that the inter-particle repulsion increases, hinder their coalescence, so that they are in good dispersion, thereby preventing or reducing scale Formation.
