EDI Automobile Exhaust Gas Treatment Solution Production And Purification Equipment
EDI main economic and technical indicators
- Pretreatment flow ≥2.5T/H;
- The first-level reverse osmosis product water ≥1.5T/H;
- Secondary RO water production ≥1T/H;
- The first-level reverse osmosis conductivity ≤15μs/cm;
- The conductivity of secondary reverse osmosis ≤10μs/cm;
- EDI product water resistivity ≥14MΩ·CM;
- Polishing mixed bed water production resistivity ≥17MΩ·CM (using nuclear grade resin) (25L inside, 35-50 tons of water per liter);
- EDI product water flow ≥1000L/H;
- Utilization rate of primary reverse osmosis water ≥65%;
- The utilization rate of secondary reverse osmosis water is ≥85%;
- EDI water utilization rate ≥90%;
- EDI service life: 3-5 years (the membrane block needs to be cleaned when the water quality and water volume do not meet the standards).
