Several water treatment technologies commonly used in water treatment equipment
Water treatment equipment for deionized water for electroplating process; pure water for battery (battery) production process; surface coating, cleaning chaotic water; pure water for coated glass; hard demineralized water required for textile printing and dyeing process; petrochemical industry Such as chemical reaction cooling water; chemical, fertilizer and fine chemical, cosmetic process manufacturing process pure water; hotels, buildings, community airport real estate property quality water supply network system and swimming pool water purification; life, hospital, leather, printing and dyeing, paper Treatment of industrial wastewater and landfill leachate.
What kinds of water treatment technologies are commonly used in water treatment equipment?
I. RO reverse osmosis membrane water treatment technology
RO reverse osmosis is a pure water machine (also known as terminal water purification equipment) that can be directly consumed by humans without filtering any raw materials by filtering the raw water (physical method) through the current international popular reverse osmosis. ).
Second, microfiltration and ultrafiltration water treatment technology Microfiltration method is a microporous membrane made of cellulose or polymer material, using its uniform pore size to intercept particles, bacteria, colloids, etc. in the water, so that it does not pass the filter And was removed. This microporous membrane filtration technology, also known as granular filtration technology, is capable of filtering micron or nanoscale particles and bacteria. Both ultrafiltration and microfiltration are membrane separation technologies. There is no obvious boundary between the two. The working pressure of ultrafiltration is generally about 0.3 MPa, which can remove macromolecular substances, bacteria, viruses, etc. in water, but the flux is more than three. Combined water treatment technology When a water treatment equipment of one process is difficult to remove harmful substances in water, two or more processes are used as a composite type. Such as activated carbon adsorption? UV sterilization, activated carbon adsorption? Reverse osmosis, activated carbon adsorption? Microfiltration (ultrafiltration), polypropylene microfiber, microfiltration (ultrafiltration).
4. Softening Water Treatment Technology There are two kinds of soft water technologies commonly used in water treatment equipment. One is to remove calcium and magnesium ions from water by ion exchange resin to reduce the hardness of water; the other is nanocrystalline technology, which is produced by nanocrystals. High energy, packs free calcium, magnesium and bicarbonate ions in water into nano-scale crystals, preventing free ions from forming scale.
V. Distillation Water Treatment Technology Distillation refers to boiling water and collecting the steam to cool and condense into a liquid. Distilled water is extremely safe drinking water, but there are some issues to be further explored. Since distilled water does not contain minerals, this has become a reason for opponents to suggest that people's life expectancy is aging. In addition, the distillation method is costly and consumes energy, and cannot remove volatile substances in water.
