Total water management solutions for process and wastewater recovery and recycling.
What is Water Recovery?
Water recovery refers to the processes used to convert wastewater into water that can be reused for other purposes. Other terms used are recycled water, wastewater reuse and water reclamation. Water is an increasingly valuable waste resource which can, when recovered, be reused for irrigation, domestic sanitary systems and industrial applications, and might be further treated to make it suitable for drinking.
How to Recover Water from Waste
Veolia Water Technologies is an expert in water treatment and water recovery. What was once considered as waste is now being viewed as a waste resource from which valuable water can be extracted. This reduces the costs involved in waste processing, helps businesses to meet increasingly demanding environmental standards and improves operational efficiencies.
We offer a number of wastewater treatment and processing systems that will recover water for reuse:
- DAF units: dissolved air flotation used in the treatment of surface water containing low-density particles
- Aerobic digestion: micro-organisms and oxygen convert organic matter into carbon dioxide
- Anaerobic digestion: micro-organisms in the absence of oxygen break down organic material, producing methane-rich biogas
- Clarification: allows suspended solids and flocs (particles) to settle, thus clarifying the water
- Evaporation: enables the removal and recovery of water
- Reverse osmosis: removes contaminants from water (demineralises and deionises) by pushing it through a reverse osmosis semi-permeable membrane
- Ultrafiltration: uses physical filtration to clarify and disinfect water by removing pollen, algae, bacteria, viruses, germs and organic molecules
- Deionisation: ion exchange is used to remove total dissolved solids from water
Benefits of Water Recovery
Recovering usable water from wastewater provides a number of benefits. Here are just some of them:
- Reduced costs - reduction in incoming water and reduced water sent to waste
- Reduced demand for freshwater from sensitive ecosystems which rely on sufficient supply
- Irrigation with recycled water can reduce the need for fertilizers in agriculture
- Recovered water can be used to irrigate public parks and green spaces
- Helps to meet the growing domestic, industrial and environmental demands for water
- Recovering water where it is needed saves energy that would be used to pump water from other locations
- Recycled water avoids the need to use drinking water for non-potable applications, such as industrial
- Water supply costs along with wastewater disposal costs are reduced
