After the reverse osmosis equipment has been in operation for a certain period of time, the conductivity of the effluent water will increase. Even if the reverse osmosis membrane has just been replaced, the conductivity of the effluent water is still relatively high. Even in the case of two-stage reverse osmosis, the conductivity of the second stage is higher than that of the first stage. What are the reasons for this? Now let's talk about the factors that can cause the conductivity of the effluent from reverse osmosis equipment to increase. The service life of reverse osmosis equipment is long. As the service life of the membrane elements extends, the salt permeability increases. Generally speaking, a high conductivity means that the entire water treatment system has not changed compared to the initial state. The reason for the high conductivity at this time is the aging of the reverse osmosis membrane module, which leads to a decrease in the desalination rate. The correct handling method is to replace the reverse osmosis membrane of the reverse osmosis main unit. 2. When the connecting parts leak, the electrical conductivity of the equipment suddenly rises during normal op
Details >The single-valve double-tank boiler water softening equipment (water softener) is a complete machine composed of a fully automatic water softening controller, a resin tank for single-valve double-tank water softening equipment, strong acid type sodium ion cation resin, and a salt tank. It is widely applied in industrial boilers, cooling circulating water, steelmaking, steel rolling, large transformers, civil hot water boilers and other occasions. Now let's introduce the continuous water supply single-valve double-tank water softening equipment (water softener). The multi-way valve in the continuous water supply single-valve double-tank boiler water softening equipment is a multi-path integrated valve that uses the reciprocating motion of the piston to switch the water flow direction during all working processes of the water softener. It also has components such as the regeneration system, brine injection flow-limiting orifine plate, and blowdown flow-limiting orifine plate. The regeneration control device in the continuous water supply single-valve double-tank boiler softened water equipment is the control part of the control valve, consistin
Details >When the water softening equipment (water softener) is in operation, it displaces the vast majority of calcium and magnesium ions in the source water. Under a certain pressure and flow rate, the source water flows through the water softening equipment (water softener) filled with ion exchange resin, and the exchangeable Na+ contained in it undergoes ion exchange with the cations (Ca2+, Mg2+, Fe2+, etc.) in the water By significantly reducing the content of Ca2+ and Mg2+ ions in the effluent from the container, the water that flows out becomes softened water with extremely low hardness. There are many factors that affect the softening effect, and resin is an important one among them. Among resins, the exchange capacity is a factor that cannot be ignored. The exchange capacity of resin refers to the number of grams (or grams equivalent) of anions and cations that can be exchanged by the exchange groups in a unit volume or weight of resin, which is a measure of the resin's exchange capacity. Now let's talk about the softening resin exchange
Details >The conference was launched in November and December 2015
As the Start of Winter approaches, the cold has already hit the whole of Beijing, and the temperature is getting lower and lower. However, this cannot dampen the enthusiasm of Beijing Yuanlai. On November 7th, it held the kick-off meeting for November and December 2015. At the meeting, the gains and shortcomings of September and October were summarized, and the goals for the last two months of this year were also set. Under the lead of each manager, the atmosphere heated up and everyone joined in the fun. Everyone danced together
Details >The process composition of laboratory pure water equipment
In the laboratories of the electronics industry, experiments are always conducted to obtain results. This process requires pure water, and the water quality standard of this pure water is very high. Generally, the electronic ultrapure water process system is usually composed of pretreatment, reverse osmosis and ultrapure post-treatment processes. When these three small processes are combined, pure water that meets the corresponding test standards can be produced. The raw water pretreatment system is typically composed of polypropylene fiber (PP) filters and activated carbon (AC) filters. For raw water with higher hardness, a softening resin filter also needs to be installed. The PP filter element can remove mechanical particle impurities larger than 5μm, rust and large colloidal substances and other contaminants in the raw water, protecting the subsequent filters. Its features are large dirt-holding capacity and low price. The AC activated carbon filter core can adsorb residual chlorine and some of it in the raw water

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.
