Overview
Chemical industry water treatment equipment produced by ultrapure water is mainly used in the battery line solvent water, chemical analysis, chemical materials, product cleaning, separation of substances, concentration, purification, waste recycling and other occasions, the requirements for water quality is relatively not too high, the purity of water conductivity from 0.1 uS/cm-20 uS/cm can basically meet the requirements. The conductivity of pure water ranges from 0.1 uS/cm to 20 uS/cm, which can basically meet the requirements. Our company can be based on the specific requirements of customers on the water quality, the use of reverse osmosis, ion exchange, EDI and other ultrapure water production process in different combinations, the production of that is economical and practical, but also to meet the customer's requirements of the chemical industry water treatment equipment water treatment equipment.
Two, chemical industry water treatment equipment process
1, chemical industry water treatment equipment using ion exchange, the process is as follows:
Raw water → raw water pressurized pump → multi-media filter → activated carbon filter → water softener → precision filter → Yang resin filter bed → anion resin filter bed → anion and Yang resin mixing bed → microporous filters → point of water
2, chemical industry water treatment equipment using two-stage reverse osmosis, the process is as follows:
Raw water → raw water pressurization pump → multi-media filter → activated carbon filter → water softener → precision filter → the first stage of reverse osmosis → PH adjustment → intermediate water tank → the second stage of reverse osmosis (reverse osmosis membrane surface with a positive charge) → purified water tank → water pump → micropore filters → point of use
3, chemical industry water treatment equipment using two-stage reverse osmosis, the flow is as follows >3, chemical industry water treatment equipment using EDI, the process is as follows:
Raw water → raw water pressurization pump → multi-media filter → activated carbon filter → water softener → precision filter → first stage reverse osmosis machine → intermediate tank → intermediate pump → EDI system → microporous filters → point of use
Three, the chemical industry water treatment equipment process comparison
Currently Chemical industry water treatment equipment process is basically the above three, the rest of the process is mostly in the above three basic process based on different combinations with derivatives. Their advantages and disadvantages are listed below:
1, the first chemical industry water treatment equipment using ion exchange resins, the advantages of its initial investment is less, occupy less space, but the disadvantage is the need for frequent regeneration of ions, consume a lot of acid and alkali, and the environment has a certain degree of destructiveness.
2, the second chemical industry water treatment equipment using two-stage reverse osmosis equipment, which is characterized by the initial investment than the use of ion exchange resin is higher, but no resin regeneration. The disadvantage is that the membrane needs regular cleaning or replacement, water quality is relatively not too high, most of them can only do 1us/cm or so, so in the quality of the requirements of the higher often use a reverse osmosis behind the mixed bed (yin and yang compound bed) gatekeeper.
3, the third chemical industry water treatment equipment using reverse osmosis as a pretreatment with electrodeionization (EDI) device, which is currently the most economical and environmentally friendly preparation of ultrapure water ultrapure water preparation process, does not require regeneration of acid and alkali can be used to continuously produce ultrapure water, there is nothing destructive to the environment. The disadvantage is that the initial investment is too expensive compared to the above two ways.
Four, Hangzhou Yongjieda Purification Technology Co., Ltd. chemical industry water treatment equipment features
Chemical industry water treatment equipment process is usually used for the production of ion exchange resin, but the use of ion exchange resin is usually required to regenerate the resin on a regular basis, that is, the cost of material resources and waste of manpower, our company has been practiced over the years, while combining the latest membrane separation technology, often used in reverse osmosis plus ion exchange system (reverse osmosis system). Reverse osmosis plus ion exchange system (or EDI) is used to prepare ultrapure water, the process has the advantage of low operating cost compared with the traditional process (the regeneration cycle of the ion exchanger is greatly extended), reliable operation. Compared with the latest process, it has the advantages of low cost and easy availability of consumables. Reverse osmosis process technology is advanced and reliable.
