Complete process technology for the treatment of surface water
Surface water can be treated into drinking water using the following physical, mechanical and chemical process steps:
- Coagulation: Dosing a coagulant to the raw wastewater
- Flocculation: Dosing a flocculant, and possibly a flocculation aid, to the raw wastewater results in the formation of flocs.
- Clarification: The flocs are separated from the water e.g. with a lamella separator.
- Filtration: The clarified water is then filtered to separate even the smallest solids and flocs. Depending on the requirements, single-layer or multi-layer sand filters can be used for this purpose.
- Disinfection: Depending on the requirements, various options are available for disinfection: sodium and calcium hypochlorite, chlorine dioxide, chlorine, ozone, UV disinfection.
The Mena-Water SafeDrink Package Plant is a cost-optimised treatment system that is available in a containerised design for quick-and-easy installation and is highly mobile.
For more extensive purification of the water, reverse osmosis can be used as a further process step. Reverse osmosis is also able to separate dissolved salts and harmful compounds. The Mena-Water Reverse Osmosis System is quickly ready for use on site with little installation effort.
