Per capita water volume in the world8354The per capita water volume is only cubic meters2285Cubic meters, it has become one of the countries with the most severe water shortage in the world. In many places across the country, ground subsidence has occurred due to excessive exploitation of groundwater. Meanwhile, a considerable portion of groundwater does not meet drinking standards. The proportion of groundwater with poor to extremely poor water quality monitored by the Ministry of Environmental Protection is57.3%. Whether it is for the reuse of water resources and water conservation or to ensure our water supply, the importance of water treatment and purification has been increasingly recognized by people. Water treatment reverse osmosis equipment is a simple, convenient, energy-saving and environmentally friendly water production device, and reverse osmosis membrane material is its core.
Reverse osmosis membranes utilize the fine pore sizes formed by molecular structures for filtration. Basically, only water molecules can pass through, while various inorganic ions, colloidal substances, and macromolecular solutes are almost impossible to pass through, thereby obtaining water that is nearly pure. Reverse osmosis equipment is regarded as having the characteristics of simple operation, compact equipment, good working environment, energy conservation and chemical reagent saving, no phase change and no secondary pollution21One of the most promising high-tech fields in the century.
According to the quality of the raw water, choosing the correct reverse osmosis scale inhibitor can effectively prevent the deposition and precipitation of inorganic salts on the surface of the reverse osmosis membrane, thereby ensuring the normal operation performance of the reverse osmosis membrane and guaranteeing the normal operation of the reverse osmosis equipment. Recommended for correct useJC-AMastering the correct usage method of a series of scale inhibitors is an important measure to make the scale inhibitors function effectively.
Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.
The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.
Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
