What is the configuration and function of industrial pure water equipment?
Raw water tank: In order to solve the problem of unstable pressure in the water supply pipe network, avoid the phenomenon that the inlet and outlet water volume is lower than the output of the raw water pump and endanger the normal operation of the equipment, you can use the following methods to reduce it.
2: Set the liquid upper and lower cable float switches.
High Level Meter: When the net inflow of source water exceeds the output of the raw water pump, the float switch will be lifted to the point where the high level meter set by the water storage tank is full, and the source water supply will be stopped.
Low level gauge: When the net inflow of sewage is lower than the output of the raw water pump, the float switch will drop to the low level gauge site, and there is a shortage of water in the raw water tank. In order to avoid the abnormal operation of the original centrifugal water pump due to drying, the original centrifugal water pump will stop working to prevent the occurrence of empty burning.
Original centrifugal water pump:
In order to ensure the normal operation of the preparatory treatment and RO system, it is necessary to solve the problem of unstable working pressure of the source water, so as to maintain the stable pressure and sufficient platform flow of the preparatory treatment inlet water.
A multi-media filter is a commonly used filter device. It uses quartz sand as the filter material, which has a good filtration effect and a long service life. The multi-media filter can effectively remove suspended solids, impurities and microbial strains in the water, and provide clean water resources. It is suitable for use in household industrial applications, mainly in wastewater treatment, swimming pool cleaning and industrial production. The application of multi-media filters can improve the water body and ensure water safety and health.
The multi-media filter is an excellent micro secondary sedimentation tank filter equipment made of FRP pressure vessel, with a pressure resistance of 6kg cm2. The filtration device is filled with ultra-wear-resistant quartz sand that has been refined, which can effectively block a small amount of fine sand, residues, colloidal substances, suspended solids and other algae plants in the raw water. It reduces the turbidity and saturation of raw water, and filters out impurities such as metal oxides, turbidity and fine particulate matter that are insoluble in water. In particular, it has excellent filtration effect in many aspects such as further reducing the turbidity of source water and air pollution index.
Activated carbon filters are a common filtration device component that is suitable for removing odors, colors, and harmful substances from water. It is made of activated carbon with strong adsorption power, which can adsorb and filter pollutants in the water. Activated carbon filters not only improve the body of water, but also improve the taste and make the water fresher. In addition, it has the effect of increasing the life of other filter elements, because activated carbon can adsorb and reduce the number of substances that other filter units may not be able to process. Activated carbon filters are widely used in drinking water equipment for domestic commercial service and are a very practical component of filtration devices.
The quartz sand filter is a pressure filter dish, made of fiberglass, which can withstand a maximum pressure of 6kg cm2. The internal structure is equipped with granular activated carbon for purifying water, which can adsorb melanin, organic compounds, free chlorine, odor and metal ions in the water, and can also remove iron, hydrogen, etc. in the water, so that the residual chlorine content in the water is reduced to 1ppm. In the process of advanced treatment and purification of water bodies, quartz sand filter is very necessary.
Dolination is the ability to remove the hue caused by environmental contaminants caused by iron, manganese and animal dissolution in raw water.
It can eliminate a small amount of environmental pollutants in raw water, including chemical fertilizers, pesticides, chlorinated hydrocarbons, ester compounds, biological oxygen consumption and permanganate index.
Removal of phenolic compounds: Removal of THMS and other products generated when preoxides and disinfectants (e.g., hydrogen) are added to water resources"Three"Odors caused by chemicals and their free chlorine.
Activated carbon can effectively remove fluoride and nitrite in water, and can also remove residual chlorine or oxides, which plays a protective role in reverse osmosis membranes.
Deodorization: Removes small amounts of metal ions (such as mercury, chromium and low-temperature plasma) in water, generates cleaning liquids and radioactivity, etc.
Softening filter device:
The softening filter device is a pressure filter dish, made of fiberglass, which can withstand a pressure of 6kg cm2. The internal structure is equipped with a special softening resin to soften the water hardness. When the raw water contains calcium (Ca2+) and magnesium (Mg2+) positive ions according to the efficacy of the booster water pump and the working pressure enters the filtration device, the softening resin will adsorb the calcium and magnesium cations in it, thereby reducing the hardness of the raw water, preventing the fouling of the pipeline, turning the water hardness into softened water, and achieving the effect of removing scale.
When the softened resin is saturated, the calcium and aluminum ions in the source water can no longer be adsorbed. At this moment, it is necessary to reconstruct the softened resin by using industrial salt to replace the adsorbed chlorite and repair the adsorption. The main function of softening resin is to adsorb calcium and aluminum ions in the source water without reducing the total salt content in the water.
The high-efficiency air supply outlet can quickly eliminate fine particles and pollutants in the air. These filters have a very small diameter and can filter out smaller fine particulate matter, ensuring a cleaner air index. It is widely used in air purification systems, medical machinery and laboratories and other industries, and has a key role in filtration. In addition, reverse osmosis equipment also has the advantages of corrosion resistance and heat resistance, and can operate efficiently for a long time.
The reverse osmosis equipment is made of stainless steel as the casing, and the internal structure is equipped with dissolved PP cotton with a filtration efficiency of 5 microns. It can filter out impurities in the approach channel of the pretreatment system, avoid the source water puncture or scratch the desalination layer on the surface of the RORO reverse osmosis membrane under the premise of high flow velocity, and extend the trial period of the RO membrane. In addition, it can also keep the incoming RO membrane water clean and completely transparent, effectively preventing the RO membrane from clogging too early.
Efficacy of high-pressure water pump:
The column type multi-stage special centrifugal water pump is used as the high-pressure water pump for the reverse osmosis system to ensure that the system has a fixed driving force supply, always maintain a stable working pressure, and the total flow is sufficient to ensure the normal operation of the system. The inlet pipe of the high-pressure water pump is equipped with a water level working pressure protection device, once the water seepage working pressure is abnormal, the high-pressure water pump will stop working to avoid destruction due to drying.
RO stands for Reverse Osmosis System, which is a specialized technology that filters water through semi-permeable membranes. It effectively removes dissolved salts and other residues from the water, resulting in clean water. RO reverse osmosis systems are generally used in industries such as sewage treatment, domestic water and industrial water. It works by applying pressure to force water through a semi-permeable membrane, separating clean water and eliminating dissolved matter. This type of technology can provide high-quality water while also conserving water.
The application of high-pressure water pump to increase the specific osmotic concentration of the source water, relying on the RO membrane separation process, can effectively extract the vast majority of particles, colloidal solutions, organic impurities, microbial strains and other harmful gases and 99% of the decomposed salts in the water with a diameter greater than 200, so as to achieve the effect of desalination and purification, and promote the conductivity of pure pure water to be less than 10 s (the conductivity of raw water is less than 300 s).
Membrane separation technology is a membrane separation device used to produce purified water. Compared with the traditional ion exchange method and distillation technology, the membrane separation technology has the following advantages: the machinery and equipment are small in size, high efficiency, strong adaptability, no need to use strong acid and alkali regenerators, advanced technology, and easy to achieve intelligence. At the same time, the pure water prepared by membrane separation technology is of excellent quality, stable water quality, no microbial strains, no metal ions, and no organic matter. The sewage discharge is not harmful to the surrounding environment and meets the requirements of environmental protection.
Large-scale industrial reverse osmosis pure water equipment is a pure water system obtained by RO reverse osmosis membrane filtration process. When the working pressure in the system exceeds the osmotic concentration of the inlet solution, the water will continue to pass through the membrane, inject into the central pipe, and then discharge the impurities in the water, such as positive ions, organic compounds, bacteria, etc., from the drain, these impurities can be left to the membrane seepage end, and then discharged from the concentrated water outlet, so as to achieve the purpose of separation and filtration.
Large-scale industrial reverse osmosis pure water equipment is composed of multi-pole high-pressure water pumps, reverse osmosis membrane elements, membrane shells (high-pressure vessels) and supports. The scope of application is to eliminate impurities in the water and promote the water output to meet the needs of use.
When RO reverse osmosis does not meet the water output requirements, aftertreatment systems are used to further improve water quality. This system mainly includes one or more of the negative bed, positive bed, mixed bed, sterilization, ultrafiltration membrane, EDI and other equipment. According to the post-treatment system, the water quality resulting from RO reverse osmosis will be further improved to meet the needs of the use.
The cleaning equipment mainly includes cleaning water tanks, cleaning pumps and reverse osmosis equipment. When the water output index value of the reverse osmosis system is polluted and does not meet the requirements, it must be cleaned to restore its normal actual effect.
The automatic control system is used to manage the operation of the reverse osmosis system. The system consists of components such as an in-vehicle instrument cluster, a control panel, different types of electrical protection equipment and a motor control cabinet.
