High filtration selectivity, regardless of the origin of the water. They are mainly used in sewage or surface water. In short, waters to desalinate with high amount of suspended solids.
DISINFECTION BY OZONE:
- Selective ion exchange resins:
Sometimes, after osmosis, it is necessary to eliminate specific odors, flavors or contaminants in order to improve the chemical characteristics of the water.
Occasionally and after osmosis, the absolute safety of having water free of pathogenic microorganisms is required to make it drinkable. For this we use chlorine, ultraviolet light, ozone …
- Electrodeionization, ultrapure water production:
Sometimes, and after one or several steps of osmosis, an exceptional quality of water product is required. This is the case of water for power generation plants, refineries, chemical plants or any industrial process that needs an additional step of water purification.
