110Overview of large-scale reverse osmosis purified water equipment with a capacity of tons per hour

The reverse osmosis device is the core component of the entire pure water equipment in large-scale reverse osmosis pure water equipment. As the basis for pure water production, it is very important. After treatment, the water can generally achieve a desalination rate of 90% -99%. Only through reverse osmosis can the standard of pure water be achieved. Due to the very small pore size of the reverse osmosis membrane, only water molecules can pass through the membrane, and other ions such as calcium, magnesium, and sodium are discharged together with the wastewater. If you want to produce good pure water, you need to choose places with good raw water quality, such as mountains, springs, deep wells, etc.

1. Raw water tank: stores incoming water (such as treated river water, groundwater, municipal tap water, reclaimed water, etc.) to provide buffering for subsequent filtration systems, avoiding situations such as insufficient water supply due to small incoming water.

2. Boosting pump: provides constant working pressure and flow rate for the pre-treatment filter.

3. Quartz sand filter: The raw water first passes through a quartz sand filter, which is filled with 0.5-1-2-4-8-16-32 quartz sand and quartz stone to trap suspended impurities such as flocs and rust in the raw water during this process. Due to the mechanical filter capturing a large amount of suspended impurities during operation, it is necessary to regularly flush and backwash the filter to ensure its normal operation.

4. Activated carbon filter: The residual chlorine in the reverse osmosis inlet water should be less than 0.1mg/L, especially when adding bleach powder to municipal tap water for disinfection. The residual chlorine content is relatively high, so activated carbon adsorption is set to achieve the inlet water index of reverse osmosis.

5. Precision filter: Filter particles larger than 5UM in water to avoid entering the reverse osmosis membrane components and causing membrane damage, which affects the performance of the reverse osmosis membrane.

6. High pressure pump: Generally, the high-pressure pump we use here is either Southern Pump or imported Grundfos multi-stage centrifugal pump, which provides strong power for reverse osmosis equipment.

7. Reverse osmosis membrane: It uses membrane filtration technology to purify water by allowing water molecules to pass through other ions that cannot pass through.
