Protective measures for the shutdown of ultra-pure water treatment equipment
Ultra-pure water treatment equipment takes the combination of RO membrane technology and EDI membrane block technology as its core technology. This new technology emerged in the late 1960s. Before that, enterprises that wanted to use ultra-pure water all prepared it through mixed bed technology. Once this kind of ultrapure water preparation equipment was introduced to the market, it was favored by the vast majority of enterprises. During the use of this equipment, there are many precautions. The following introduces the measures adopted for the shutdown protection of ultrapure water treatment equipment. When the ultrapure water treatment equipment is not in operation for a long time, relevant protective measures need to be implemented. In the case of long-term non-use of the equipment, the reverse osmosis membrane elements and precision filter elements in the equipment should be protected. Long-term shutdown usually refers to a shutdown of more than ten days. The reverse osmosis membrane elements need to use a concentration of one percent
Details >Precautions for the operation of water treatment equipment in winter
In winter, the temperature is low. Water treatment equipment operating under such low-temperature conditions is prone to problems. Now let's talk about the precautions for the operation of water treatment equipment in winter. In winter, due to the extremely low temperature, the water supply pipes are prone to burst. If the water supply pipes freeze and crack or the water supply is cut off, try not to use the equipment (especially the tankless machine) during the water outage. Close the inlet ball valve. After the water comes back, first open the tap water to discharge the sediment and other substances in the water supply pipes, and then open the inlet ball valve to let the reverse osmosis water purification equipment work. Avoid the entry of impurities such as sand and rust mixed in during the construction process into the reverse osmosis equipment, which may cause the filter element to be clogged in a short time and lead to a decrease in water production flow. The water production volume decreases, and the lower the temperature, the greater the decline in water production flow. This is because the viscosity of water is affected by temperature, and the reverse osmosis membrane
Details >When does a quartz sand filter need to be cleaned and backwashed?
Quartz sand filters are generally used as pretreatment for reverse osmosis and ultrafiltration equipment, mainly for the retention and adsorption of silt, colloids, metal ions and organic matter. Common filter materials include quartz sand, activated carbon, anthracite, manganese sand, etc. It is widely applied in various industries such as agricultural irrigation, chemical engineering, petroleum, metallurgy, and mining. Now let's talk about when quartz sand filters need to be cleaned and backwashed? Firstly, the cleaning and backwashing of quartz sand filters are for different operational purposes. Cleaning is an action carried out when the efficiency of backwashing declines. Backwashing is to remove the pollutants captured in the filter, ensuring that the filter's filtration function can continue to operate. The following is an introduction to the differences between the two. The operation timing of backwashing for quartz sand filters is mainly determined by the decrease in the flow rate of the circulating pipeline per unit time
Details >How to maintain a household water purifier?
With the improvement of living standards, more and more families choose to secretly switch to household water purifiers. Among them, the filter core is the core component of the equipment, which directly affects the water quality of the output. To use it reasonably, let's talk about how to maintain household water purifiers below? After using a water purifier for a long time, it is necessary to frequently flush it. This can effectively extend the service life of the water purifier. 2. If the tap water supply is cut off, remember to first open the drain valve to completely remove the sediment, rust and other impurities in the tap water pipe, and then open the purified water to use the purified water. 3. With long-term use of the water purifier, its water output will gradually decrease, but the water quality produced remains qualified and can be used with confidence. 4. Sometimes we may have to go on long trips. If the water purifier is not used for more than three days, when it is used again, it should be flushed forward repeatedly for 2 to 5 minutes until all the water in the purifier is drained
Details >What causes the water hardness of the softened water equipment to be high?
The sampling port test of the softened water equipment was qualified, but the water hardness in the softened water tank exceeded the standard mainly due to the following reasons: A. The resin softening regeneration cycle was set too high, or the softened water flowmeter malfunctions, causing inaccurate measurement, which prevented the cation exchange resin from being regenerated in time when it should have been regenerated, resulting in hard water exceeding the standard being injected into the softened water tank. B. The forward wash time is too short, causing part of the waste brine that should have been washed away during the forward wash to be carried into the softened water tank. The sampling port of the fully automatic water softening equipment has been tested multiple times, but all have failed. The main reasons are as follows: A. The O-ring at the junction of the pipe and the fully automatic softening control valve has not formed A seal. At this time, the following should be checked: ▲ Whether the length of the pipe is sufficient and whether the outer diameter meets the requirements ▲ Whether the O-ring seal was forgotten to be installed

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.
