Due to the presence of various insoluble microorganisms, organic matter, colloidal substances, dissolved gases, and particles in water, different processing methods need to be combined and matched to produce water with a water quality of at least 10M Ω· cm for places such as electronics, electricity, chemical engineering, electroplating, boiler supply, hospitals, and laboratories.
For producing water with a resistivity of 10M Ω. cm or more, reverse osmosis water treatment technology, deionized water, EDI ultrapure water, softened water and other technologies can be used. Let's take a look at the common pure water equipment on the market: a small primary reverse osmosis pure water treatment equipment with a capacity of 5 tons per hour.
Industrial principle of reverse osmosis pure water treatment equipment:
This pure water equipment can achieve a one-time removal of over 98% of ions, organic matter, and 100% of microorganisms from raw water, producing pure water with a water resistivity of around 18M Ω. cm.
After being treated by a first stage reverse osmosis equipment, the conductivity of the incoming water (groundwater or tap water) is less than 10 μ S/cm. If the industrial water quality requirements need to reach a higher stage, further treatment is required. The water conductivity treated by a second stage reverse osmosis water treatment equipment is less than 5 μ S/cm or even lower.
Advantages of pure water equipment:
Excellent effluent quality: Reverse osmosis membrane water treatment technology can not only desalinate but also remove trace organic matter and particles such as SiO2 from water. This water treatment technology is superior to ion exchange method in terms of effluent quality.
Easy to operate: The device can choose to use a fully automatic system for processing, and during the operation of the device, the staff only need to watch.
Stable water production: The equipment mainly uses physical processes during the treatment period, can operate continuously for 24 hours, and has stable water output.
