Details >Softening water equipment (softeners) mainly reduces the hardness of water by softening resins. These softening resins are also called ion exchange resins and are high-molecular compounds. Therefore, their performance varies due to differences in manufacturing processes, source formulas, polymerization temperatures, and crosslinking agents. Winter is approaching. How does temperature affect ion exchange resins? The following main performance is introduced in two parts. (1) Physical properties A. Appearance Resin is a transparent or semi-transparent substance. Due to its different compositions, it comes in various colors. For instance, styrene resin is yellow, but it can also be black or brown. However, this has little impact on its performance. Under normal circumstances, if there are more impurities in the raw materials or more crosslinking agents, the color of the resin will be slightly darker. Particle size can be represented by the effective particle size and the coefficient of non-uniformity. B. The size of the resin particles will affect the exchange rate, pressure loss and backwashing
Details >Factors affecting the effect of ultraviolet rays in water treatment
In water treatment, we often use ultraviolet devices. So, what factors can affect the effectiveness of ultraviolet rays? The power of the lamp tube: The power of the ultraviolet lamp tube decreases as the usage time increases, and its radiation effect declines. When the lamp tube is used for a certain period of time, the emission intensity will decrease. In the future, to ensure product quality, the ultraviolet lamps should be replaced in a timely manner before reaching the critical value of their usage time. 2. The power supply voltage should be kept stable to ensure the stability of radiation. 3. Water flow velocity and the distance the water layer is exposed to radiation: When the water flow rate is constant, a large flow area, a slow water flow velocity, and sufficient residence time of the water body within the shell are conducive to disinfection. However, the larger the diameter of the shell and the thicker the water layer, the farther it is from the lamp tube, and the worse the disinfection effect will be. According to the information available, a 30w ultraviolet lamp is suitable for

Details >What methods should be used to remove iron and manganese from water in water treatment?
The water contains excessive iron and manganese and is not suitable for domestic drinking or industrial production. This kind of water quality mostly occurs in underground water sources. What methods should be used to remove iron and manganese from water? The process for removing iron from water consists of three parts: aeration, oxidation reaction and filtration. The pH value of water has a significant impact on the oxidation reaction rate of divalent iron. By aeration and oxygenation to remove part of the CO2, the pH can be raised to above 7.0, which can achieve a good oxidation reaction of divalent iron and the flocculation and sedimentation of trivalent iron. Then, the iron can be removed through filtration. However, there is often a small amount of dissolved silicic acid in water. As a result, the SiO (OH) 3- ions in water strongly adsorb onto the surface of the trivalent iron hydroxide colloid, making it difficult for the trivalent iron hydroxide to alternately coagulate and causing it to penetrate the filter layer, thereby affecting the iron removal effect. Therefore, the contact oxidation method is widely adopted for removal

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.
