Ultrafiltration reverse osmosis water reuse equipment

Reverse osmosis principle
Reverse osmosis, abbreviated as RO, is the selective permeation of certain components in a solution under external pressure, achieving desalination, purification, or concentration separation. It is called reverse osmosis because it is opposite to the direction of natural osmosis. The main separation object of reverse osmosis membrane is the ion range in the solution, which does not require chemicals and can effectively remove salt from water. The desalination rate of the system is generally above 98%, which can effectively remove dissolved salts, colloids, bacteria, viruses, bacterial endotoxins, and most organic impurities in water. So reverse osmosis is the most advanced, energy-saving, and environmentally friendly desalination method, and has also become the mainstream pre desalination process

Reverse osmosis characteristics
The series of reverse osmosis devices developed by our company use reverse osmosis membranes from companies such as HyderautiCS or Dow (such as HYDRANAUTICS, DOW-FILMTEC), reverse osmosis membrane shells from companies such as COLDLINE and WAVECYBER, and booster pumps from companies such as GROUDFOS and LOWARA. Not only are the processes advanced, but the product quality is reliable, the scalability is strong, the structure is reasonable, and the footprint is small. The water utilization rate and product life are well balanced, with low energy consumption, fully automatic operation, and simple operation and maintenance.

Application scope of reverse osmosis
1.Preparation of sterile and heat free purified water in the pharmaceutical and pharmaceutical industries;
2.Ultra pure water for the electronics and power industries;
3.Chemical and cosmetic ingredient water;
4.Desalination of brackish water and seawater;
5.Cleaning, distribution, and cooling water for precision machinery, special materials, optoelectronic materials, and quartz product industries;
6.Drinking purified water, food and beverage water.

Ultrafiltration principle
Ultrafiltration is a membrane separation process based on the principle of sieve separation and driven by pressure. The filtration accuracy is within the range of 0.005-0.01μm, which can effectively remove particles, colloids, bacteria, heat sources and polymer organic substances in water. It can be widely used in mineral water purification, deep treatment of drinking water and separation, concentration and purification of substances. In recent years, it has been applied to the pre-treatment of the reverse osmosis system to effectively reduce the SDI of the reverse osmosis influent, extend the service life of the reverse osmosis membrane and improve the economy of the system.

The recycling of industrial wastewater is a circular economy behavior, and its role is:
Firstly, it can reduce environmental pollution caused by wastewater discharge;
Secondly, it can save a lot of processing costs;
Thirdly, it can save water;
Fourthly, useful substances can be recovered from wastewater.
Industrial wastewater treatment and reuse equipment adopts dual membrane combined technology to perform secondary deep treatment of industrial wastewater, meeting the requirements of production process water use. The dual membrane method is a combination process of ultrafiltration and reverse osmosis (RO). Ultrafiltration serves as a pretreatment for reverse osmosis, which deeply removes organic matter and salts that cannot be removed by ultrafiltration. The effluent quality is very high.
