UF + RO + EDI equipment for containing ultrafiltration equipment, microfiltration equipment, reverse osmosis equipment, EDI equipment and so on. The process is a combination of ultrafiltration, microfiltration, reverse osmosis, EDI and other different membrane processes, can effectively remove pollutants and deep desalination of water treatment process. Full membrane ultrapure water equipment water can directly meet the user's water needs, the process has been successfully applied to electric power, metallurgy, petrochemical and other fields.

Second, factory direct 0.5t water purification equipment _ 1000L / H two-stage reverse osmosis + EDI ultrapure water system process characteristics:

The key technology of ultrapure water equipment process EDI system electrodialysis (ED) and ion exchange technology (DI) organic combination, to achieve continuous desalination, simple operation and maintenance, no acid and alkali emissions pollution. In the membrane treatment system, used as a pre-treatment of ultrafiltration generally use the diameter of 1mm hollow fibres to remove suspended solids and colloids in the raw water, UF used as a pre-treatment of the problem of membrane contamination and clogging of the membrane holes, which is often set up in front of the pre-filter in order to remove large-size suspended solids in the pre-filtration of the pre-flocculating agent, such as PAC (polyacrylamide acid) to improve the filtration of water quality, and to reduce the resistance of the membrane. Power plant boiler make-up water system requirements of dissolved oxygen is generally required for the following 0.3 mg / L, the degassing membrane should be in less than 5.33Kpa (40TORR) under vacuum operation. The control system adopts industrial computer programme control, which can achieve automatic start and stop, dosing and flushing, and automatically monitor various operating parameters for production management.

Third, factory direct 0.5t purified water equipment _ 1000L / H two-stage reverse osmosis + EDI ultrapure water machine system extraction process:

1, using ion exchange, the process is as follows:

Raw water → raw water pressurisation pump → multi-media filter → activated carbon filter → water softener → precision filter → positive resin filter bed → negative resin filter bed → anion and Yang resin mixing bed → microporous filter → water points

2、Adopting reverse osmosis + mixed bed method, the process is as follows:

Tap water network → raw water pump → flocculation and dosage → mechanical filter → activated carbon filter → scale inhibitor and dosage → security filter → high-pressure pump → reverse osmosis device → intermediate water tank → mixed-bed pump → mixed-bed device → precision filter → demineralised water tank

3、Adopting EDI method, the flow is as follows:

Raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → a reverse osmosis machine → intermediate tank → intermediate water pump → EDI system → microporous filter → water point Comparison of the preparation process

Fourth, factory direct 0.5t purified water equipment _ 1000L / H two-stage reverse osmosis + EDI ultrapure water machine system scope of application:

1, for thermal power plants and large and medium-sized industrial and mining enterprises boiler make-up water treatment.

2, the use of the world's most advanced reverse osmosis membrane elements, pressure vessels and other equipment, with a reasonable and have pre-treatment and post-treatment equipment, can be produced in line with the national or industry boiler water supply standards (GB1576-79, DL/T561-95) ultrapure water.

3, in the membrane treatment system, used as a pretreatment ultrafiltration generally use 1mm diameter hollow fibre to remove suspended solids and colloids in the raw water, UF used as a pre-treatment of the problem of membrane contamination and clogging of the membrane holes, often set up in front of the pre-filter for the removal of large-size suspended solids in the pre-filtration before the addition of flocculants, such as PAC (polypropylacetic acid) to improve the filtered water quality, and to reduce the resistance of the membrane.

4, the power plant boiler make-up water system requirements of dissolved oxygen is generally required for the following 0.3 mg / L, the degassing membrane should be in less than 5.33Kpa (40TORR) under vacuum operation.

5、The control system adopts industrial computer programme control, which can achieve automatic start and stop, dosing and flushing, and automatic monitoring of various operating parameters for production management.
