Description
Water consumption and wastewater disposal are critical challenges in the steel and metallurgical industries. Conventional reverse osmosis (RO) systems, widely used for producing demineralized water in cooling circuits, generate a concentrated waste stream (25-50% of feed water), which requires disposal due to high levels of calcium, magnesium and other contaminants.
At Contec Industry, we apply our WASM method, a sustainable approach aligned with ISO 14046 and ISO 14001 standards, to optimize water reuse and reduce environmental impact. Our solution integrates vacuum evaporation technology with waste heat recovery, converting excess thermal energy (hot water or steam) into a resource for water treatment. This enables the production of low-salinity distillate for reuse, minimizing fresh water intake and wastewater discharge.
The presentation will be accompanied by a real-world case study, demonstrating the practical application and benefits of this innovative solution in an industrial setting.
Key Benefits:
- Reduced Water Consumption: Maximizing reuse of treated water in cooling circuits and wastewater treatment plants (WWTP).
- Lower Wastewater Discharge: Decreasing the volume of reject water, reducing environmental burden.
- Enhanced Energy Efficiency: Utilizing available heat from industrial processes, lowering energy demand.
- Cost Savings: Cutting operational costs for osmotized water production.
- Sustainability & Compliance: Improving the water footprint of the facility and contributing to ESG performance.
This approach exemplifies how circular economy principles can drive efficiency in industrial water management. By transforming waste heat into an asset, steel plants can achieve significant environmental and economic benefits, aligning with global sustainability goals.
