Reverse Osmosis Equipment

Pharmaceutical wastewater is one of the most difficult industrial wastewater to treat due to its complex composition, many types of organic pollutants, high concentration, high COD and BOD values and high volatility, large differences in BOD/COD values, high concentrations of suspended solids and NH3-N, deep chroma, and difficult biodegradation and toxic substances.

Deionized water equipment is an ion exchange system. Ion exchange means that when water passes through the ion exchange column, the cation in water and the anion in water (HCO- plasma) exchange with the H+ of the positive resin and the OH- of the negative resin in the exchange column, so as to achieve the purpose of desalting. Different combinations of Yang and Yin mixed columns can make the water quality reach higher requirements. Ion exchangers are divided into cation exchangers (softeners), anion exchangers, mixed ion exchangers, etc. The disadvantage is that the resin needs to be regenerated with acid and alkali after saturation.

Pure water equipment generally includes pretreatment system, reverse osmosis device, post-treatment system, cleaning system and electrical control system. The pretreatment system generally includes raw water pump, dosing device, quartz sand filter, activated carbon filter, precision filter, etc. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine to meet the influent requirements of reverse osmosis. The reverse osmosis device mainly consists of multi-stage high pressure pump, reverse osmosis membrane element, membrane shell (pressure vessel), bracket and so on. Its main function is to remove impurities in the water and make the water meet the requirements of use.

 The post-treatment system is added when reverse osmosis does not meet the effluent requirements. It mainly includes one or more kinds of equipment such as Yin bed, Yang bed, mixed bed, sterilization, ultrafiltration, etc.

The cleaning system is mainly composed of cleaning water tank, cleaning water pump and precision filter. When the reverse osmosis system is polluted and the effluent index cannot meet the requirements, it is necessary to clean the reverse osmosis to restore its efficacy.

The electrical control system is used to control the normal operation of the whole reverse osmosis system. Including instrument panel, control panel, various electrical protection, electrical control cabinet and so on.

Pure water equipment, which uses mainly reverse osmosis membrane technology. Its working principle is to exert a certain pressure on the water, so that the water molecules and ionic mineral elements through the reverse osmosis membrane, and most of the inorganic salts dissolved in the water (including heavy metals), organic matter and bacteria, viruses, etc., can not pass through the reverse osmosis membrane, so that the penetrated pure water and the concentrated water can not be strictly separated; The aperture on the reverse osmosis membrane is only 0.0001 micron, while the diameter of viruses is generally 0.02 to 0.4 microns, and the diameter of ordinary bacteria is 0.4 to 1 micron.

Brackish water desalination equipment, suitable for high saline-alkali areas and seawater backfilling areas, the use of reverse osmosis membrane elements, high-quality pressure vessels, and high pressure pumps, with reasonable pretreatment equipment, can effectively remove the inorganic salts, heavy metal ions, organic matter, bacteria and bacteria and other harmful components in the water, the brackish water desalination into the national standard of drinking water quality water.

Seawater desalination equipment refers to the equipment specially used to desalinate seawater. Seawater desalination mainly uses two methods to desalinate seawater, namely distillation method and reverse osmosis method.

Reverse osmosis water treatment equipment is usually composed of three parts: raw water pretreatment system, reverse osmosis purification system and ultra-purification post-treatment system. The purpose of pretreatment is to make the raw water meet the water intake requirements of the reverse osmosis membrane separation component and ensure the stable operation of the reverse osmosis purification system. The reverse osmosis membrane system is the most economical and efficient purification method to remove more than 98% ions, organic matter and 100% microorganisms in raw water at one time (theoretically).

Utilizing the reverse osmosis principle, the reverse osmosis equipment is an equipment that uses membrane separation technology to enable solution to go through the reverse osmosis membrane and effectively separate solvents for the solution.
