2. Working Principle
Process Flow
Raw water → Multi-media filter → Carbon filter → Softener → 5μm filter → HP pump → RO → EDI → UV → 0.22μm filter → PW storage → Distribution.
EDI
Electrodeionization combines ion exchange resin and membranes under DC field. Ions migrate through membranes to concentrate chamber. Resin continuously regenerated electrically. No chemicals needed. Output 15–18 MΩ·cm.
