Maintenance: RO (0.25T/H type, 0.5T/H type, 0.75T/H type, 1.0T/H) reverse osmosis equipment integrates the perfect and formal drinking water production process into one, with clear processes and easy maintenance .

Purified water equipment process description:

The first-level pretreatment system: the quartz sand multi-media filter is used, the main purpose of which is to remove the silt, manganese, rust, colloidal substances, mechanical impurities, suspended solids and other substances in the water that are harmful to the human body with particles above 20UM. The automatic filtration system adopts imported Fleck controller, which can automatically carry out a series of operations such as backwashing and forward washing. At the same time, the equipment has a self-maintenance system with low operating costs. Filter materials mainly include: PPF, AC coconut carbon and so on.

The second-level pretreatment system: the activated carbon filter is used to remove pigments, odors, and a large amount of biochemical organic matter in the water, and reduce the residual chlorine value in the water, pesticide pollution and other pollutants harmful to the human body. The automatic filtration system adopts imported Fleck controller, which can automatically carry out a series of operations such as backwashing and forward washing.

The third-level pretreatment system: use cationic resin to soften the water, mainly to remove the hardness in the water. The hardness of water is mainly composed of calcium (Ca2+) and magnesium (Mg2+) ions. When the raw water containing hardness ions passes through the resin layer, the Ca2+ and Mg2+ in the water are exchanged and absorbed by the resin, and at the same time, sodium and Na+ ions are released at the same material quality. The water flowing out of the water softener is softened water from which the hardness ions have been removed. So as to effectively prevent the fouling of the reverse osmosis membrane. The system can automatically carry out recoil, front flush and so on. And intelligent resin regeneration can be carried out to extend the service life of the system.

The fourth-level pretreatment system: the use of 5 micron pore size precision filter to further purify the water, so that the turbidity and color of the water can be optimized. Ensure the water inlet requirements of the RO system. The main system of the purified water equipment adopts reverse osmosis technology for desalination. The pore size of the reverse osmosis membrane is only 0.0001 micron, which can remove harmful soluble solids, bacteria, viruses, etc., and the desalination rate is over 99.6%, producing pure products that meet national standards. For water, the host part includes a security filter, a high-pressure pump and a reverse osmosis membrane. The security filter is the fourth-level pretreatment system above. The high-pressure pump is one of the core equipment on the host, which provides sufficient pressure for the reverse osmosis membrane element. In order to overcome the osmotic pressure and operating resistance, the device can meet the rated water output.

  Ozone sterilization system Ozone has strong oxidizing properties and has four major functions: sterilization, oxidation, decolorization, and deodorization. When used for water disinfection, when the concentration is 4mg/l, it can kill all bacteria in 0.5-1 minutes. Ozone is dissolved in water to form oxygen-rich water, which ensures the pure freshness of the water without losing water activity.
