Siemens EDI membrane block EDI membrane stack

1、 SiemensIONPUREEDIThe membrane block system mainly consists ofIP-LX-ZSeries, SiemensEDIMembrane blockediThe membrane stack has the following specifications and models:

Siemens membrane stacks can be used in industries such as power, electronics, food, and beverages, as well as providing high-quality solutions for laboratorieshigh purity waterNo need to shut down for regeneration.

2、 SiemensEDIMembrane blockediWater inlet requirements for membrane stack:

The water inlet of LX module must have an equivalent conductivity less than10μs/cmofreverse osmosisWater production (including carbon dioxide and silicon)

temperature5-45℃

Water inlet pressure20-100 psi (1.4-7bar)

total chlorine(usecl2count) <0.02 ppm

Iron ion<0.01ppm

manganese<0.01ppm

sulfide<0.01ppm

ph value4-11

total hardness(useCaCO3count) <1.0 ppm

TOC (TOC)CCalculation)<0.5 ppm

silicon(Sio2) <1.0ppm

3、 Same as other brandsEDISystem comparisonSiemensEDIMembrane blockedimembrane stackThe advantages of the product lie in:

1IONPURE CEDINo need to inject saltwater circulation, no need to use chemicals, compared to other brandsEDIIt is necessary to inject saltwater circulation into the concentrated water layer to reduce the membrane resistance value;

2IONPURE CEDIUsing patented layered resin arrangement technology in concentrated water layers to reduce membrane resistance, while other brandsEDIHigh purity and hardness free refined salt is required to increase operating costs;

3IONPURE CEDIThe conductivity of concentrated water is20-100us/cmWuji Water, while other brandsEDIThe conductivity of concentrated water is200-400us/cm 2%Extreme water discharge;

4IONPURE CEDIRaw water flows into the concentrated water layer and is directly recovered without the need for a circulation pump, unlike other brandsEDIIn the concentrated water layer, a circulation pump is required to maintain continuous water flow circulation;

5IONPURE CEDISimple piping, only need to be equipped with a main water pipe, product water outlet pipe, and concentrated water return pipe, while other brandsEDIWater inlet pipe, product water outlet pipe, concentrated water return pipe, circulating water pipe, and electrode water pipe are required;

6IONPURE CEDIIndependent membrane module power control, when a single membrane module needs maintenance or malfunctions, it does not affect the operation of other membrane module groups, while other brandsEDIAll membrane modules share one power control, and in the event of a single module failure, the entire system must be shut down

4、 SiemensEDIMembrane blockediCharacteristics of membrane stack:

1. The quality of the produced water is equivalent to or better than that of mixed bed produced water, and no chemical agents are required;

2. Continuous water production and stable water quality without fluctuations;

3. No need for acid-base neutralization, no need for acid-base storage tanks;

4. Fully filled concentrated water chamber, no need to add salt or circulate concentrated water;

5. Can be in100PSI，45Continuous operation at Celsius degrees;

6. DoubleOSeal the ring to ensure no leakage;

7. Super strong electrical insulation performance;

8. Operating costs are much lower than traditional onesion exchange
