Industrial electrodeionization membrane stack uses continuous electrodeionization technology to produce high-purity water

Share:

Product Description

Industrial electrodeionization membrane stack uses continuous electrodeionization technology to produce high-purity water, which can produce high-purity water with stable quality extremely reliably without interrupting operation due to regeneration. The membrane stack can be used in the power, electronics, food and beverage industries and laboratories.

Feature

● Double O-ring seal guarantees leak-free operation

● Generate mixed-bed quality deionized water without the use of chemicals

● Continuous production instead of batch, with consistent quality

● No need for acid/caustic, neutralization system or exchangable DI tanks

● Superior electrical isolation

● 100 psi (7 bar), 113˚F (45˚C) continuous operation

Operating Environment

Installation should be indoors with no direct sunlight and should have a maximum ambient om temperature of 113°F (45℃).

Quality Assurance Standards

CE marked. Each module is factory tested to meet strict industry standards and is manufact- ured in an ISO 9001 and ISO 2000 quality and environmental management system.

FAQ

Q: If the environment is a two-stage RO, if the EDI product water quality deteriorates, what should be checked?

A:Chlorine gas/residual chlorine may enter the EDI system, causing the ionic resin to be oxidized and the quality of the product water to decrease

Suggestion:Use residual chlorine meter or ORP meter for influent water quality monitoring, residual chlorine value is less than 0.02ppm or ORP is less than 150mV

Main dechlorination methods: Granular activated carbon (most reliable); Reducing agent (most economical)


Q: What should we check if the voltage is too high or too low during the first operation?

A: Generally, this situation will not happen, constant current 2-3A automatic adjustment


Q: Can high temperature water disinfection function?

A: EDI modules that can only provide measurement of water not exceeding 65 degrees; 85 degrees high temperature EDI modules will be launched at the end of this year


Q: The customer's on-site power supply is DC24V or AC110V or AC220V. Can EDI be directly connected to the power supply?

A: DC 0-400V adjustable, 0-6A adjustable, generally use constant flow or constant pressure.


Q: What are EDI consumables? Are there any parts that need to be replaced?

A: No


Q: How long is the warranty and maintenance?

A: 3-year
