1. Composition of two-stage water treatment and purification equipment
The reverse osmosis pure water treatment system generally includes a pretreatment system, a reverse osmosis device, a post-treatment system, a cleaning system and an electrical control system. The pretreatment system includes a raw water pump, a dosing device, a quartz sand filter, an activated carbon filter, a precision filter, etc. Its basic function is to reduce the pollution index of the raw water, residual chlorine and other impurities, and meet the water inlet requirements of the reverse osmosis device.
Water treatment and purification equipment mainly includes multi-stage high-pressure pumps, reverse osmosis membrane elements, membrane shells (pressure vessels), brackets, etc. Its main function is to remove impurities in the water and make the water meet the use requirements. The post-treatment system is added when the reverse osmosis cannot meet the water outlet requirements.
2. Features of two-stage water treatment and purification equipment
1. High water permeability and high desalination rate. Usually, ≥98%
2. It has a high interception and removal effect on organic matter, colloids, particles, bacteria, pathogens, etc.
3. The separation process remains unchanged and the stability is reliable.
4. Low energy consumption, high water utilization rate, and lower maintenance cost than other desalination equipment.
5. Simple operation. Easy to maintain, strong adaptability and long service life.
3. Design features of dual-stage water treatment and purification equipment
1. Deep filtration of water is achieved by increasing the pressure on the water. Water treatment and purification equipment includes not only general filters, but also fine filters and activated carbon filters. Fine filters have more delicate filtration functions than ordinary filters and can better filter impurities in water. Activated carbon has a good effect on taste. Impurity adsorption and filtration function. Water treatment and purification equipment uses dual activated carbon filters to achieve deep filtration processing of source water, which improves the filtration efficiency of the equipment.
2. The core of water treatment and purification equipment is the application of reverse osmosis membrane. Reverse osmosis membrane is a filter membrane with a very small pore size, which can achieve ultra-fine filtration of source water, and at the same time can convert water into high concentration and low concentration. High-concentration water can be recycled, and low-concentration water is pure water for people to use.
