In addition, the nanofiltration water is low corrosive, has a positive impact on the service life of the drinking water pipe network and the dissolution of metal ions in the pipeline, and is beneficial to protect all materials of the water distribution system. The results show that the application of the nanofiltration membrane system can reduce the dissolution of lead by 50%, and the concentration of other dissolved metal ions can meet the requirements of drinking water quality standard. Volatile organic compounds (vocs) removal: the removal rate of trace vocs in drinking water is good. Above article source chongqing bi pure purification equipment co., LTD. Small make up, if there is any demand, welcome to inquire.
Carbon particles are not easy to lose, can be recycled, used for less pollution, continuous operation of the water treatment process. Powder carbon is not easy to recover, generally used for one-time use, used for intermittent water treatment process with serious pollution. The microporous and mesoporous activated carbon of feed water treatment should meet three requirements: large adsorption capacity, fast adsorption speed, good mechanical strength. In addition to the above characteristics, the smaller the particle size, the better the adsorption effect. The adsorption of activated carbon can be divided into physical adsorption and chemical adsorption. Physical adsorption mainly occurs in activated carbon rich micropores, used to remove impurities in water and air, the molecular diameter of these impurities must be smaller than the diameter of activated carbon. Different raw materials and processing processes result in different microporous structure, specific surface area and pore diameter of activated carbon, which is suitable for different needs. Activated carbon not only contains carbon elements, but also contains functional groups on its surface, which can react with adsorbed substances, and adsorbed substances often occur on the surface of activated carbon. Impurities in the medium continuously enter the porous structure of activated carbon through physical adsorption and chemical adsorption, so that the adsorption saturation of activated carbon, adsorption effect decreased. After adsorption saturation, activated carbon needs to be activated and regenerated to restore its adsorption capacity and reuse. The adsorption performance indexes of activated carbon were mainly methylene blue value, iodine value and caramel adsorption value, etc. The larger the adsorption capacity, the better the adsorption effect.

Antifreeze: the preservation environment of the resin should be in the surrounding environment >40℃, if the temperature is lower than 5℃, in order to prevent the resin from freezing, the resin can be placed in an aqueous solution of table salt. Antidryness: because the water content of the resin disappears in use or storage, the volume of the resin expands and shrinks, which leads to the crushing or mechanical strength reduction of the resin and the loss or reduction of the ion exchange capacity. In this case, do not throw the resin directly into the water, but first soak it in saturated salt water, so that it slowly expand not broken.
The second step is to evenly load the resin into the resin tank. Remove the sealing tape of the center tube, rinse the upper part of the center tube and the end face of the resin tank with water and wipe clean, and coat the sealing ring of the center tube and controller with silicone oil. This step is also to protect the controller, in use is also a good protection. The third step is the water distributor and center tube must be tight, pay attention to: the water distributor and control valve, center tube. Prevent the resin from escaping. The center pipe and control valve must be tight and watertight, otherwise there will be channeling hard water phenomenon. The water distributor is installed on the control valve and the center tube is inserted into the control valve from the water distributor. Carefully turn the control valve clockwise until it is tightened to the resin tank interface (or secured with a flange). Make sure the center tube is inserted into the valve body. After the installation should be carefully checked, timely improve the emergence of vulnerabilities, to ensure its work efficiency.
At the same time, chongqing bichun purification equipment co., LTD is also a professional water treatment equipment company equipped with water quality testing laboratories in southwest China.
Somebody came in and asked the water treatment industry why they use ozone? Today and the small make up together to learn about: ozone is a strong oxidizer, contain traces of synthetic organic pollutants of water quality, conventional water treatment process cannot remove, using ozone oxidation, make not easily biodegradable COD chemical oxygen demand (COD), become BOD biodegradable oxygen consumption, to solve the water pollution problems in biological treatment. Biological treatment is economical, so when biological treatment sewage treatment to a certain extent, the use of ozone, and then biological treatment, can remove a small number of pollutants.

Water purifier using note 4: correct cleaning water purifiers clean water purifier water on a clean basin commonly, unscrew the filtering core of up and down the upper on the dome, there are two layers of non-woven cloth, with a new toothbrush brush gently in the water is clean, the lower unscrewed a plastic cover, there are two layers of non-woven cotton and sand, each brush clean gently in the water, then put a filter in the water after the shake up and down, the final rinse water purifiers, and can be installed according to the original appearance, about every other month or so, will be clean.
R0 membrane has no ability to remove small molecules such as C02, so the pH of reverse osmosis water is more acidic. Remove or add alkali to adjust the pH value according to the application. Since there is no residual chlorine in the water, if the water needs to be transported over a long distance, disinfectant must be added and a certain amount of residual chlorine maintained. Analyze the incoming water quality and the water quality through the water regularly. In particular, strictly control the incoming water quality to ensure the reliable operation of the pre-treatment measures to ensure that the SDI of the incoming water is below 3. When the amount of water through the reduction of excessive or unqualified water quality, to immediately clean the membrane regeneration, if the regeneration is still not improved, it should be timely replacement of membrane components, welcome to inquire chongqing bi pure.
Ii. Types of water treatment equipment? There are a lot of water treatment products in the market at present, but the use of water treatment according to different circumstances, according to the user's water requirements to choose, can not be generalized. Water treatment equipment according to the use of different materials, the use of different filter elements, divided into water purifier, pure water machine, soft water machine. Water purifier: the type of water purifier is also a lot of, according to the use of the number of filter is divided into coarse filter water purifier: the general use of PP fiber cotton, activated carbon, there is a primary filter water purifier, secondary filter water purifier, three filter water purifier, four filter water purifier and five filter water purifier. At the same time according to the use of different central technology is also divided into coarse filtration, hollow fiber precision filtration, ceramic filter element precision filtration. It mainly depends on what kind of filter element is used.

Distillation water treatment technology distillation is the boiling of water and the collection of steam to cool it and condense it into a liquid. Distilled water is extremely safe drinking water, but there are some issues that need to be explored further. Since distilled water contains no minerals, this has led opponents to argue that people tend to age over their lifetimes. In addition, distillation has high cost, consumes energy and cannot remove volatile substances in water. Boiling method water treatment technology boiling method refers to drinking tap water after boiling, this is an ancient method, widely used in China. Boiling water can kill, but it can't remove some chemicals and heavy metals, even in very low levels, so it's still not safe to drink.
