The ultra pure water equipment consists of a pre-treatment, RO reverse osmosis server, and a post-treatment process. The pre-treatment of ultrapure water equipment is carried out to better remove residues that affect the reverse osmosis membrane and maintain the reverse osmosis device. So, how many common pre-treatment system software are there for ultrapure water equipment?

1、 Stone sand filtration device

Stone sand filtration is one of the most effective ways to remove suspended solids in water, and is a key module in deep wastewater treatment, wastewater recycling, and water supply and drainage solutions. Its function is to further remove air pollutants from the inclined plate sedimentation tank in the water. Based on the interception, foundation settlement, and adsorption effects of the filter material, it achieves the goal of purifying water. The raw water generally contains fine particles of dust, cassava starch, methyl cellulose, and other microbial species such as bacteria and algae. The colloidal solution particles generated by the residue and water, due to the electrostatic induction of Brownian motion, exhibit the reliability of foundation settlement and convergence. Generally, they cannot be removed by natural foundation settlement under the action of force.

2、 Activated carbon filter

Activated carbon filter is a common water purification equipment. As a software pretreatment for sewage treatment desalination system, it can not only adsorb the permanganate index that cannot be removed in the previous filtration, ensure the service life of subsequent machinery and equipment, improve the water quality of filtered effluent, and avoid environmental pollution; In addition, it can also adsorb small molecule water organic compounds and other pollutants that have leaked back from previous stages, and has a significant adsorption and removal effect on odors, colloidal solutions, melanin, heavy metal ions, and other pollutants in water.

3、 Precision filter

Precision filters, also known as multimedia filters, have the function of intercepting more than 2% of the raw water μ M particles are used to ensure that the reverse osmosis membrane is not scratched by suspended solids of large particles. Due to the thickness of the reverse osmosis membrane being approximately 10 μ Up and down, large particles in the raw water can easily scratch the desalination skin on the surface of the reverse osmosis membrane or potentially penetrate the reverse osmosis membrane components after being accelerated by the high-pressure water pump. Generally, a 5-micron precision filter is installed in front of the reverse osmosis membrane machine equipment. In water treatment equipment, fine filtration is generally used as the final process for the raw water entering the reverse osmosis membrane adhesive to avoid potential leaks in the previous process and prevent blockage of the reverse osmosis membrane.

Above is a detailed introduction to several common pre-treatment system software for ultrapure water equipment. The protection equipment of ultrapure water equipment maintains it reasonably, which is one of the key components of machine equipment.
