The effect of ultraviolet devices on water and precautions for their use
The ultraviolet device is made of 304L or 316L stainless steel both inside and out. The inner and outer surfaces of the main body are polished to enhance the ultraviolet irradiance and ensure that the object will not have any problems during the process.

Details >The specific features and water treatment applications of EDI pure water equipment and EDI modules
The EDI equipment fills ion-exchange resin between the anion/cation exchange membranes to form an EDI unit. In the EDI component, a certain number of EDI units are separated by a mesh to form a concentrated water chamber. Positive and negative electrodes are also set at both ends of the unit group. Under the drive of direct current, the cations and anions in the fresh water flow pass through the cation and anion communication membranes respectively and enter the concentrated water chamber, where they are removed in the fresh water chamber. The water passing through the concentrated water chamber carries ions out of the system and turns them into concentrated water. EDI equipment generally uses reverse osmosis (RO) pure water as the feed water for EDI. The resistivity of RO pure water is generally 40-2μS/cm (at 25℃). The resistivity of EDI pure water can be as high as 18 MΩ.cm(at 25℃), but depending on the application of deionized water and the system equipment Settings, EDI pure water is suitable for preparing pure water with a resistivity requirement of 1-18.2MΩ.cm(at 25℃).
Details >Filtration, as a conventional water treatment process, plays an effective role in reducing turbidity in domestic drinking water and industrial water treatment. The material used for filtration is called filter material, which purifies water. The types of filter materials include quartz sand, anthracite, activated carbon, fiber balls, etc.
Details >The wide application and precautions of ion exchange softening water resin
Ion exchange resins can also be classified into styrene-based resins and acrylic resins based on the type of their matrix. The types of chemically active groups in resins determine the main properties and categories of the resins. Firstly, they are classified into two major categories: cationic resins and anionic resins. They can respectively undergo ion exchange with cations and anions in the solution. Cationic resins are further classified into strongly acidic and weakly acidic types, while anionic resins are divided into strongly basic and weakly basic types (or further classified into medium-strong acidic and medium-strong basic types).
Details >Today, with an increasing emphasis on health, more and more people are beginning to pay attention to drinking water health and water usage. However, due to the abundance of impurities and scale in general water quality, it can pose a threat to the body and easily lead to the formation of stones and other conditions. The water purified by the pure water equipment is very suitable for drinking. It can promote the balance of water-based electrolytes in the body, accelerate the transformation of customs and practices, and at the same time ensure the water supply for food, beverages, hospitals and other industrial and daily life. During the operation of the equipment, it is necessary to pay attention to the regular replacement of accessories, reverse osmosis membranes, filter elements, water treatment filter materials, etc., to ensure the service life of the equipment and the quality of the effluent.

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.
