Recycling industrial wastewater is crucial to ensuring that effluent meets quality standards before it is discharged into the environment or reused. Here’s an overview of the main aspects of water quality and industrial water treatment:
Characteristics of industrial water
Industrial water may contain :
- Chemical pollutants: heavy metals, hydrocarbons, organic solvents.
- Nutrients : Nitrogen, phosphorus, which can cause eutrophication.
- Suspended solids: Debris, fine particles.
- Microorganisms: Bacteria, viruses, which can be pathogenic.
Effluent quality standards depend on the regulations in force in each country or region. They generally include limits for :
- Biological Oxygen Demand (BOD): Indicator of organic pollution.
- Chemical Oxygen Demand (COD): Measure of total pollution.
- Heavy metal concentration: Specific standards for metals such as lead, mercury, etc.
- pH: Must be within an acceptable range to avoid toxicity.
Once treated, industrial wastewater can be reused in certain industrial processes to make considerable savings on water resources.
Recycling saves water. A variety of technologies and adapted processes ensure that treated water meets the required quality standards.
