1TPH Ultrapure Water Equipment With Polishing +EDI System
I.Overview
Polishing is a fine purification step that removes residual impurities, trace ions, or organic matter after water has undergone primary purification treatment (such as softening, sedimentation, filtration, or reverse osmosis). The goal is to achieve ultrapure water quality or meet specific process requirements.
Bipolar EDI: Incorporating a bipolar membrane (BPM) into the EDI module not only removes impurities but also electrolyzes water, splitting it into H⁺ and OH⁻, directly producing acids and bases. Bipolar EDI can produce ultrapure water and generate acid and base solutions as byproducts.

III.Conventional EDI vs Bipolar EDI Comparison Table
| Feature | Conventional EDI (Electrodeionization) | Bipolar EDI (Bipolar Electrodeionization) |
| Main Function | Removes ions to produce ultrapure water | Removes ions to produce ultrapure water and simultaneously generates acid/alkali online |
| Membrane Structure | Cation/anion exchange membranes + ion exchange resin | Cation/anion exchange membranes + bipolar membranes (BPM) + resin |
| Water Quality | 15–18 MΩ·cm resistivity, suitable for ultrapure water systems | Same: up to 15–18 MΩ·cm resistivity |
| By-products | None | Dilute acids (HCl, H₂SO₄) and alkalis (NaOH, KOH), reusable |
| Applications | Semiconductor, pharmaceutical, power plant boiler feedwater, laboratory ultrapure water | Ultrapure water + acid/alkali demand, wastewater resource recovery, green chemical processes |
ldentify needs
Clarify the following issues, you can determine the right equipment for you
Water quality problems
Example 1: sediment exceeds the standard / scale / turbid water / microbial exceeds the standard/ heavy metal exceeds the standard / money Yu exceeds the standard, etc.
Water standard
Example 1:Softened water/pure water/ultra-pure water/iron and manganese removal/sediment removal/sterilisation etc.
Daily Water Consumption
Example 1:Whether there is a concentrated water consumption period/water consumption time/peak maximum water consumption/hourly average water consumption
Conclusion Example
5 tonnes per hour water softening equipment.
3 tonnes per hour reverse osmosis water purification equipment
If you can't answer the above questions clearly?
1.Daily Water Consumption:Just mail a bottle of water sample
2.Water Standard:Just tell me your industry.
3.Water Consumption:We can help you to calculate the water consumption.
