Common questions about the process flow and operation of reverse osmosis equipment
Reverse osmosis is a membrane separation technology that uses pressure as the driving force and the mechanical energy of selectively permeable (semi-permeable) membranes. When the pressure applied in the system is greater than the osmotic pressure of the feed water solution, water molecules continuously pass through the membrane, flow through the product water channel into the pipe, and then flow out from one end. Impurities in the water, such as ions, organic matter, viruses, etc., are retained on the feed water side of the membrane. Then it flows out from the concentrated water outlet end, thereby achieving the purpose of separation and purification. Reverse osmosis equipment can block all dissolved salts and organic substances with a molecular weight greater than 100, but allow water molecules to pass through. The desalination rate of reverse osmosis composite membranes is generally over 98%. They are widely used in the preparation of industrial pure water and electronic ultrapure water, the production of drinking purified water, boiler feed water and other processes. Using reverse osmosis equipment before ion exchange can significantly reduce the operating
Details >Generally speaking, the operating pressure requirement for water softening equipment is 0.2-0.5MPa. There are two reasons for this pressure requirement: when the pressure is greater than 0.2MPa, it is to ensure the salt absorption effect of regeneration. Since the fully automatic water softening equipment relies on water pressure to form negative pressure to extract salt water, the pressure at the upper end of the salt suction device directly affects the speed and effect of salt suction. Generally speaking, if the pressure is lower than 0.18MPa, the salt suction effect will significantly decline. If the pressure exceeds 0.5MPa, the salt absorption effect can of course be guaranteed, but at this time, the pressure on the pipeline part is too large, and leakage is prone to occur at each connection point. In addition, due to excessive water pressure, the internal components of the multi-way valve may be under excessive pressure, which may cause inaccurate operation of the multi-way valve and directly affect the working effect. If the pressure is too high, when the equipment is running
Details >A brief introduction to the regeneration of British Polite resin
To ensure that the resin can play its role and maintain good properties during use, the rational application of PUROLITE resin is of great significance for extending the resin's service life. Here we summarize three situations where anion resins are contaminated by regeneration acid for everyone. There are three situations where the British Polite resin can be contaminated. Due to poor stratification, the anion and cation resins will mix together. When the cation resin is regenerated, this part of the anion resin is often worn or broken, causing the particles to become smaller and the density to decrease, and they will mix with the anion resin and be difficult to separate. At this time, the anion resin is prone to acid contamination. One situation is due to design reasons, such as the middle drainage pipe being designed too high, causing the anion resin to be at the lower part of the middle drainage pipe, or because the ratio of cation and anion resins is not right during resin filling
Details >How to effectively solve the problem of excessive iron and manganese in groundwater?
Beijing Yuanlai provides: Friends living in rural areas or the suburbs of cities may encounter the following phenomena: After painstakingly digging a self-provided well, the freshly drawn water is particularly clear and no different from tap water. However, after being left for a period of time, such as a few hours or overnight, the color becomes darker. "Yellow" And it gives off a fishy stench. Everyone has no idea what's going on. They all think that the water must have been polluted or that some chemical substances have reacted in it. In fact, these are all very normal and common phenomena. Because groundwater is rich in minerals and does not come into contact with air, it has been in an anaerobic environment for a long time. In this environment, iron and manganese ions exist in a divalent form. Once they come into contact with air, they will be oxidized into yellow precipitates of trivalent iron, which is why people see the water turning yellow
Details >Common fault analysis of reverse osmosis equipment
The application of reverse osmosis equipment is becoming increasingly widespread. This equipment adopts reverse osmosis membrane separation technology and is an important device for removing most of the salts, viruses and other impurities in the raw water. It is also a key treatment link to ensure the quality of the effluent from the equipment. How can we ensure the better operation of reverse osmosis equipment? Let's take a look at the faults of reverse osmosis equipment and their analysis and handling below. Fault analysis of reverse osmosis equipment: The fault phenomena of reverse osmosis equipment mainly fall into three categories: reduced water permeability, increased salt permeability (decreased desalination rate), and increased pressure drop. However, there are many causes for these faults. It is necessary to try to identify the essence of the problem from these fault phenomena, so as to implement maintenance and repair measures as soon as possible. Common problems in reverse osmosis equipment are the decline in desalination rate and the reduction in product water volume.

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.
