Water Reuse in Industrial Processes

Detailed overview of innovation with sample startups and prominent university research

What it is

Water reuse in industrial processes involves capturing, treating, and reusing wastewater generated within industrial facilities. This can include reusing treated wastewater for cooling systems, boiler feedwater, cleaning operations, or even as an input in certain manufacturing processes. The goal is to minimize freshwater intake, reduce wastewater discharge, and create a more circular and sustainable approach to industrial water management.

Impact on climate action

Water reuse in industrial processes significantly enhances water use efficiency by reducing freshwater consumption and wastewater discharge. This innovation minimizes environmental strain, conserves resources, and mitigates pollution. Its implementation fosters sustainable practices, aligning with climate action goals by curbing water-related emissions and preserving ecosystems vital for climate regulation.

Underlying
Technology

Wastewater Treatment Technologies: A variety of technologies are employed to treat industrial wastewater, including:
- Membrane Filtration: Microfiltration, ultrafiltration, nanofiltration, and reverse osmosis membranes are used to remove contaminants based on size and charge.
- Advanced Oxidation Processes: These processes utilize powerful oxidizing agents, like ozone or ultraviolet light, to break down persistent organic pollutants in wastewater.
- Biological Treatment: Activated sludge processes and other biological treatment methods utilize microorganisms to break down organic matter and remove contaminants from wastewater.
Water Reuse Applications: Treated industrial wastewater can be reused for various purposes, including:
- Cooling Water: A major application, as cooling systems require significant water volumes.
- Boiler Feedwater: Treated water can be used to generate steam for industrial processes.
- Process Water: Some industries can integrate treated wastewater directly into their manufacturing processes.
- Irrigation: Treated wastewater can be used for irrigating landscaping or agricultural crops near industrial facilities.
