What are the operation modes of ion exchangers
What are the operation modes of ion exchangers? This article analyzes the changes in conductivity at the end of the operation of a unitized ion exchanger and explains that the end point of a unitized ion exchanger can be determined by the changes in the online conductivity value. This method is used to determine the endpoint instead of the conventional approach of simultaneously analyzing SiO2 and conductivity. Engineers from Beijing Yuanlai will briefly introduce the operation mode of the ion exchanger. Ion exchangers have several operation modes based on different replacement methods: (1) Co-current regeneration and co-current softening mode: Both the raw water and the reduced liquid enter from the top of the exchanger and flow downward. In this method, the water flows from top to bottom. As the flow direction of the water is consistent with that of the reducing solution, the reducing solution cannot undergo a good reduction reaction with the ineffective exchanger, resulting in waste
Details >What should I do if the reverse osmosis device produces low water and doesn't work?
After many users purchased reverse osmosis devices, they found that the water production of the reverse osmosis devices began to decline. In response to this phenomenon, we will explain to users the reasons for the decrease in the water production of reverse osmosis equipment. 1. Reduction of reverse osmosis membranes. Operate according to the number of membranes initially designed. 2. Low-voltage operation. It should be operated in accordance with the working pressure required by the equipment. 3. Membrane module compaction occurs. When the pressure exceeds the standard, the membrane module will become compacted. At this point, the membrane module needs to be replaced. 4. The working temperature drops. It should operate in accordance with the prescribed temperature. 5. Oil has entered. It should be noted that oily substances must not enter the equipment. 6. Operate at a high recovery rate. When the recovery rate is higher than 75%, the concentrated water decreases and the concentrated water in the membrane rises, resulting in a decline in the produced water.
Details >The Hazards of scale - Boiler softened Water Equipment
1. Fuel waste - The thermal conductivity of scale in boiler softening water equipment is very poor. It is dozens of times or even lower than that of steel. The presence of scale will deteriorate the heat transfer condition of the boiler's heating surface, increase the flue gas temperature, and increase fuel consumption. According to experiments, if there is 1mm thick scale on the inner wall of the boiler, 3-5% more coal will be consumed. 2. Damaging the heating surface - Due to the poor thermal conductivity of scale in the boiler softening water equipment, and the fact that scale is prone to form on the metal heating surface with a high heat load. At this point, the temperature of the metal wall at the scaling area will be too high, causing a decrease in metal strength. Under the action of pressure, the overheated area will deform, bulge, and even lead to accidents such as explosions. At the same time, scale can also cause under-deposit corrosion of metals. Under the condition that there is scale adhering to the water-cooled wall tubes of the boiler

Details >Faults Encountered in the Use of Water softening Equipment (Beijing Yuanlai)
Water softening equipment is also known as water softening devices, water softeners, water softeners, water softening equipment, and water quality softeners. He 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 be intelligently regenerated and recycled. Its main uses: softening and desalination, electronic descaling devices, filtration and separation, boiler softening, industrial softening equipment, softening devices, household tap water softening, etc. When reverse osmosis equipment is used to treat groundwater to produce pure water, a water softening device is also configured to fully remove calcium and magnesium ions from the water. The composition of a resin softening device: A resin softening device uses the principle of ion exchange to remove scale-forming ions such as calcium and magnesium from water. It is usually composed of a controller, a resin tank, and a salt tank

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.
