13T/HHigh purity water equipment,Secondary reverse osmosisEDIDesign principles for ultra pure water treatment equipment

1. The principle of equipment is to reduce costs, have low operating expenses, and occupy a small area.

2. The processing system is advanced, the equipment runs stably and reliably, the maintenance is simple, and the operation is convenient.

3. The sewage treatment system does not generate secondary pollution sources that pollute the environment.

4. Control management should consider self-control as much as possible according to the requirements of the processing technology, in order to reduceUltra pure water equipmentThe labor intensity of running operations.

Raw water tank → Source water pump → Quartz sand filter → Activated carbon filter → Softening filter → Security filter → First stage high-pressure pump → First stage RO reverse osmosis host → PH regulating device → RO production water tank → Second stage high-pressure pump → Second stage RO reverse osmosis system → Pure water tank → EDI booster pump → Precision filter → EDI module → Ultra pure water tank

III3T/HHigh purity water equipment,Secondary reverse osmosisEDICharacteristics of Ultra Pure Water Treatment Equipment

useSecondary reverse osmosisThe technology of EDI, the characteristic of EDI membrane block is to replace it with electric field and ion membraneion exchange resinThe chemical regeneration of the equipment has significant advantages in terms of structure, operation, and operating costs compared to reverse osmosis mixed bed, and overcomes the problem of wastewater discharge caused by regenerated resin. It can be directly discharged without the need for wastewater treatment facilities.

1. EDI is used in conjunction with RO, and the current can be adjusted to change the water quality. The water output can be changed by combining standard modules. The EDI ultrapure water system operates stably at a pressure of 100 pounds per square inch (7kg/cm2), with an effluent resistivity of over 16M Ω· cm and a Si content below 20ppb. The water quality is reliable and meets the strict industrial water quality requirements currently.

2. EDI does not require resin regeneration, eliminating the need for resin chemical regeneration supporting facilities such as acid and alkali storage tanks, pumps, and pipelines, simplifying the system equipment structure, saving investment, simplifying operation, and reducing operating costs. The equipment investment, installation, and operation costs are calculated based on a 10-year amortization period, with an EDI investment coefficient of 10%. EDI is relatively low in low flow conditionsmixed-bed systemIt is much more economical and quite effective in high traffic situations. In the above comparison, the costs of land occupation and environmental management were not considered, and EDI has a clear advantage in this regard.

3. The technical and economic comparison also shows that EDI is more adaptable to TDS changes in the influent than mixed bed systems without affecting the effluent quality, and has little impact on water production costs.
