（1） Application scenarios
1. Cold rolling wastewater treatment (including oil and emulsion)
2. Reuse of washing water for blast furnace gas
3. Purification of turbid circulating water in continuous casting
4. Zero discharge of sintering flue gas desulfurization wastewater

（2） Membrane technology solution
● Pre treatment: Ceramic membrane oil removal (oil content ≤ 5mg/L)
Deep processing: ultrafiltration+reverse osmosis (desalination rate ≥ 98.5%)
● Zero emissions: DTRO+evaporative crystallization (salt recovery rate ≥ 95%)

（3） Technical advantages
● Increase the recycling rate of water resources to 90%
Reduce hazardous waste generation by 70%
The consumption of new water per ton of steel has been reduced to below 3.5m³
