Large scale reverse osmosis equipmentThe water production usually exceeds20ton/Hourly, tap water is used as raw water, which undergoes pre-treatment before being further processedROreverse osmosisAfter a series of processing, etc,Can remove harmful substances such as particles, colloids, organic impurities, heavy metal ions, bacteria, viruses, and heat sources from water99%The dissolved salt has a desalination rate of up to 96～99%. However, large-scale reverse osmosis equipment is also divided into single-stage reverse osmosis and two-stage reverse osmosis (secondary reverse osmosis). Most industries use single-stage reverse osmosis equipment (primary reverse osmosis equipment) for effluent conductivity ≤10μs/cmIndustries such as pharmaceutical equipment adoptSecondary reverse osmosisProcess, effluent conductivity can reach2-5μs/cm

125T/HProcess principle of large-scale reverse osmosis equipment:

1. Quartz sand filter:Remove a portion of larger solid particles or easily settling impurities from the water. To intercept small particles and impurities in water, thereby further clarifying and purifying the water, and reducing its turbidity to less than5mg/LIt can effectively remove a large amount of organic matter, bacteria, viruses, etc. from water as the turbidity decreases.

2. Activated carbon filter:Activated carbon is widely used in domestic water, food industry, chemical industry, power and other industrial and domestic water. due toactivated carbonIts specific surface area is large, and its surface is covered with an average diameter of20~30Ah（A）Due to its micropores, activated carbon has a high adsorption capacity. In addition, the surface of activated carbon has a large number of functional groups such as hydroxyl and carboxyl groups, which can be used for washing, chemical adsorption, and electrostatic attraction of various organic substances. Activated carbon adsorption is the utilization of the excess surface energy of molecules on the surface of activated carbon due to uneven force distribution. When a substance collides with a solid surface, it is attracted and stays on the surface of activated carbon, thereby achieving decolorization, deodorization, removal of heavy metals, various dissolved organic compounds, radioactive elements, etc. Remove harmful substances from water. Water purifying activated carbon filter material, with an iodine value of1200The above has undergone acid washing treatment, resulting in particle diameter8-16The eyes. It can effectively adsorb residual chlorine in water.

3. Softening system: Softening iscation exchange resinWhen water passes through it, it adsorbs away calcium and magnesium ions in the water, thereby achieving softening effect. Generally, this is due to the high calcium and magnesium ions in local groundwater. When using reverse osmosis technology for pure water equipment, calcium and magnesium ions can causeROThe blockage of the membrane directly increases the removal of ion components from waterROThe service life of the membrane.

4. RO reverse osmosis device:Reverse osmosis technology is commonly used for desalination of seawater and brackish water; Softening treatment of water; Limestone treatment: Calcium and magnesium ion treatment: Wastewater treatment, as well as purification, concentration, separation, and other aspects of industries such as food, electronics, electroplating, pharmaceuticals, and direct drinking water. In addition, the application of reverse osmosis technology in pre desalination treatment has also achieved good results. Therefore, it saves costs and is also beneficial for environmental protection. The low-pressure polyamide composite membrane produced by the world's advanced American company Heidelberg is used as the main component, and the desalination rate of the system is99%The above effectively removes suspended solids, organic colloidal substances, harmful bacteria, viruses, pyrogens and other impurities from water, ensuring that the effluent quality meets national standards.

5. Security filter:Security filtering adoptsPPCotton melt blown filter cartridge filtration.PPCotton can accumulate smaller suspended solids, colloids, pathogens, and other substances to ensure subsequent stabilityROThe normal operation of the system. Ensure the safe and hygienic supply of water even in the event of previous process failures.

II25T/HLarge scale reverse osmosis equipmentWhat are the characteristics?

1. The operation is clear and simple, it can be said to be easy to understand at a glance, intelligent control, and can be completed by pressing the switch when needed.

2. After being installed and debugged by professional personnel, it can run normally.

3Reverse osmosis water treatment equipmentIt can achieve fully automatic operation, save a lot of manpower, and reduce the burden of work fatigue.

4. Large scale reverse osmosis equipment has the function of free protection, and under normal operation, there is no need for manual monitoring.

5. Humanized design, a low-pressure protection switch is installed at the inlet of the high-pressure pump. When the pressure of the high-pressure pump drops below 0.05, the pressure controller will activate, causing the equipment to stop working and ensuring the safety of the high-pressure pump and personnel.

6. A slow opening electric valve and a high-pressure switch are installed at the outlet of each high-pressure pump. When the outlet pressure exceeds 2.0Mpa, the pressure controller will activate to stop the equipment and ensure the safety of the high-pressure pump, membrane components, and membrane casing.

7. The body of the large-scale reverse osmosis equipment is equipped with various data monitoring, which is clear at a glance

8. Install an online conductivity meter on the main inlet pipe of the reverse osmosis system to monitor the quality of the raw water;9Reverse osmosis deviceInstall one fresh water flow meter and one concentrated water flow meter on top, observe the operation status of reverse osmosis based on the two flow values, and adjust the system recovery rate;
