Technical process of pure water production line
Apr 15, 2019
Here we would like to share the technical process of pure water production line as following,
The pretreatment process of the pure water production line equipment factory is mainly used to improve the influent water quality, which can effectively reduce the pollution of membrane components and prolong the service life. The pretreatment is mainly for microorganisms, bacteria, colloids, organic matter, heavy metal ions and solids in the influent water. Impurities such as particles and free chlorine are removed. Meet the requirements of the reverse osmosis unit water supply, and ensure the long-term stable operation of the reverse osmosis membrane system.
Quartz sand filter
The large-scale pure water equipment quartz sand filter mainly removes suspended solids, colloids, sediment, clay, rot plants, particulate matter and other impurities in the water, reduces the turbidity of the water, and the pure water water plant equipment achieves the purpose of water quality clarification, and protects the reverse osmosis membrane. .
Activated carbon filter
Activated carbon filter mainly uses activated carbon to have a large number of functional groups such as hydroxyl and carboxyl groups, which can chemically adsorb substances of various natures to remove odor, organic matter, colloid, iron and residual chlorine in water, and reduce the color and turbidity of water. Reduce pollution to reverse osmosis.
Automatic softening device
The sodium ion on the ion exchange resin is used to exchange calcium and magnesium ions in the water to reduce the hardness in the water, and the ion exchange resin is regenerated with the salt.
Security Overthinker
The 5 micron polypropylene wound fiber filter is used as the filter element, mainly to remove the particles of more than 5 micrometers that have not been removed by the pretreatment system, and to remove the filter material lost before the treatment, thereby protecting the RO membrane from being less polluted. Whether the filter element can reach normal use conditions will affect the normal working conditions of the membrane.
Reverse osmosis system
The system includes high pressure pumps, reverse osmosis membranes, membrane casings, cleaning systems and related piping, valves, measuring instruments, etc. The reverse osmosis first-order salt rejection rate is above 98%, and the reverse osmosis water production conductivity is less than 20 μS/cm.
Cleaning and sterilizing equipment
1.ozone sterilization machine
Ozone sterilization is widely used in the production of purified water. It prevents the stagnant water in the pipeline and the walls of the vessel from growing bacteria and affecting the water quality. Therefore, the addition of ozone to the water eliminates the growth of microorganisms.
2.CIP cleaning device
When the reverse osmosis membrane element is used for a long time, it must inevitably lead to certain pollution, such as fouling of inorganic substances, bacteria, and microorganisms. At this time, the water production of the device is reduced, and the desalination rate is reduced. This system is mainly used for cleaning the reverse osmosis element to restore its normal working capacity.
In order to ensure the normal operation of the pure water equipment system and prolong the service life of the reverse osmosis membrane element, when the reverse osmosis system is operated for a period of time, it is necessary to remove calcium carbonate scale, metal oxide scale in water, biological growth (bacteria, fungi, mold, etc.) The substance needs to be cleaned of the system.
Pure water tank
After the ion exchanger product water enters the pure water tank, it passes through the pure water tank pipeline to each water point. In order to meet the GMP verification requirements, the pure water tank is equipped with an air breathing apparatus to prevent the air from entering and leaving the air when the water level rises and falls. Dust and microbes ensure that pure water is not contaminated. It is equipped with a spherical sprinkler and uses a chemical solution to clean the inside of the pure water tank.
Introduction to the process characteristics of pure water production line system
1. The main accessories of the system are imported fittings with strong stability.
2. The reverse osmosis concentrated water is used for pre-treatment backwashing, which meets the water saving requirements.
3. The ultra-low pressure anti-pollution reverse osmosis membrane selected has the characteristics of low pressure, high flux, high salt rejection and pollution resistance.
4. The pure water production line equipment adopts high-efficiency pretreatment system to ensure the biological stability of reverse osmosis water and slow down the pollution of the subsequent reverse osmosis membrane. At the same time, the pretreatment equipment can perform backwash regeneration to ensure the stability of the pretreatment system.
