Process flow of water softening treatment equipment and boiler water softening equipment
Softened water equipment, also known as softened water devices, water softeners, water softeners, water softening equipment, and water quality softeners, is mainly used for softening and desalination, electronic scale removal, filtration and separation, boiler softening, industrial softening equipment, and household tap water softening, etc. Softening water equipment uses cation resin to soften the source water. The main purpose is to have the cation resin adsorb calcium and magnesium ions (the main components of scale) in the water, reduce the hardness of the source water, and it can also perform intelligent resin regeneration and be recycled. Specification: Automatic/Manual The effluent quality meets the national standard for low-pressure boiler feed water. Time control - timing type; Flow control - metering type. 1. To save costs, users can choose manual control systems according to their conditions. 2. If the user is 24 hours
Details >Types and advantages and disadvantages of filter tanks
The applicable conditions, advantages and disadvantages of several commonly used types of filters are as follows: (1) Conventional rapid filters and double-layer filters are suitable for influent turbidity less than 20NTU, and can be less than 50NTU in the short term. It is used in large, medium and small water treatment plants, and the area of a single pool is generally no more than 100 square meters. The operation and management of the common rapid filter tank is convenient, but it has many valve components and is prone to leakage, so a dedicated flushing device is required. The double-layer filter has a high filtration rate and a long working cycle, and can be transformed from a common rapid filter. However, the selection of filter materials is strict, the flushing operation is rather strict, and it is prone to sludge sedimentation. (2) Contact double-layer filter, which is direct filtration, is suitable for small-scale water treatment plants with a capacity of less than 5000m ³ /d, and the influent turbidity requirement is less than 150NTU. Its advantages are that it can purify raw water at one time, requires fewer treatment structures, occupies less land, and has low infra

Details >Selection criteria for laboratory ultrapure water machines
The selection of a laboratory ultrapure water machine mainly depends on the quality of the raw water, the amount of water used, and the quality of the water used. There are three types of water quality for national laboratory standards: Grade one water, Grade Two water, and Grade Three water. However, most laboratories only need two types of water quality. The first is Grade three water, such as distilled water, which is used for cleaning glassware, etc. The second type is grade one water, which is mainly used for chemical analysis or precision instrument analysis such as liquid chromatography and atomic absorption. Customers should select the grade of the ultrapure water machine based on their actual water quality requirements. All ultrapure water machines that use tap water as the water source have two (two types of water quality) outlets. One is pure water, that is, grade three water. The second type is grade one water, namely ultrapure water (strictly speaking, the resistance of grade one water is greater than 10MΩ.cm, while that of ultrapure water is greater than 18MΩ.c)
Details >Analysis of the Causes of Contamination of Polite Cation and Anion Exchange Resins
When the surface of the Polite ion exchange resin is covered with iron compounds or the exchange channels inside the resin are blocked by iron impurities, etc., the working exchange capacity and regeneration exchange capacity of the resin are significantly reduced, but the structure of the resin remains unchanged. This phenomenon is called the "iron" of the resin. "Poisoning" . "Causing perlite resin iron" "Poisoning" The main reasons are fourthly: 1. The water source is groundwater with a high iron content or surface water contaminated by iron. 2. The inlet pipe or the interior of the exchanger has been corroded, resulting in the formation of iron compounds. 3. The regenerant contains iron impurities. 4. The water contains large-molecule organic substances. The iron of the Perlite cation exchange resin "Poisoning" It generally only occurs in the process of softening water with salt as the regenerant, and there are mainly two situations. One is when iron is gelatinous

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.
