Process water treatment
Process water is water that is used in industrial operations for purposes such as washing, cooling, heating, diluting and transporting products. Once used, it may be contaminated with pollutants such as oils, greases, suspended solids, chemicals and metals, and therefore requires appropriate treatment before it can be discharged into the environment or reused.
Several treatment solutions are possible, depending on the nature of the water and specific needs:
- Settling and filtration to remove suspended particles.
- Physico-chemical treatment (coagulation, flocculation, neutralisation) to separate pollutants.
- Biological treatment to degrade organic matter using micro-organisms.
- Membrane technologies (ultrafiltration, reverse osmosis) to obtain very clean water.
- Disinfection (UV, chlorine) to eliminate bacteria.
Tertiary wastewater treatment
The aim of the tertiary treatments is to eliminate the undesirable matters such as suspended solids, the DCO (hard and colloidal), phosphorus, and specific compounds such as (pesticides, metals, detergents…). They aim at improving the water quality purified for their rejection in the natural environment or of their re-use. The tertiary treatments come in complement from the primary treatments and secondary treatments.
EMO can offer you treatment solutions, including tertiary filters and various filtration methods, such as sand filters or carbon filters.
These solutions reduce environmental impact, ensure compliance with regulations and, in some cases, enable water to be reused in order to preserve this valuable resource.
