Water Recycling & Reuse for industries
Water is an essential production material for most industrial sites. In some industries, such as the microelectronics production, it is one the most significant expenses. Increasing droughts, floods, regulation, competition over abstraction, change the water availability and quality, and lead many industries to look for alternative resources.
Specific issues to consider for industrial sites
- Ensure an uninterrupted and constant quality water supply, and avoid risks of plant shutdown due to water shortage
- Reduce your cost of water consumption and wastewater management Integrate into future changes in local regulation and national policy
- Take advantage of best practice and regulation such as the BREF
- Improve your Corporate Responsibility report through the reduction of environmental impacts
Veolia Water Solutions & Technologies have proven experience of industrial water production through recycling, in most industries and provide adaptive and high performance technological solutions and associated services in the design, build and commissioning of water treatment plants.
Various configurations and cases
- On-site water recycling
- Cascade recycling of at the point-of-use
- Reuse of treated municipal wastewater and storm water
- Zero Liquid Discharge
Recycled water can respond to most industrial water needs from utility water (washing, cleaning, fire fighting, irrigation) to boiler feed water, process water and ultra-pure water.
Specific water treatment technologies and processes also respond to the diversity of industrial applications.
- White water and condensates recycling in the Pulp & Paper industry
- Recycling of produced water in the Oil & Gas industry
- Loop-recycling of chemical baths
- Rinsing baths, solutions, metal recovery
