Treatment of drinking water
It is well-known that for hygiene reasons as well as reasons related to the treatment technology of drinking water, water coming from springs or water-wells is primarily used. However, the ever-increasing consumption, especially in densely populated areas, can no longer be met. Thus, one is obliged to reside to the use of surface water so as to fulfill long or short term demands for fresh water. The treatment of water before consumption is essential so that the water with which one ends up meets the health and safety regulations for drinking water. Essential processes are filtration, flocculation with products certified for the treatment of drinking water, and disinfection by appropriate means.
The purpose of FERI-TRI SA is to supply the companies responsible for drinking water with appropriate chemical products to curb unpleasant side-effects in humans.
Treatment of swimming - swimming-pool water
The water of any swimming pool, small or large, must be cleaned on a daily basis so as to avoid contraction of various diseases that may be transmitted through pool water. Necessary treatments are filtration, flocculation with products certified for the treatment of drinkable water and disinfection by appropriate means. The purpose of FERI-TRI SA is to supply swimming pools with necessary chemical products so as to avoid unwanted consequences for human health.
Treatment of municipal wastewater
Municipal water is the liquid waste generated during cleaning processes (cooking, laundry, toilets, etc.) in a residential area (offices, schools, houses, etc.). The treatment of urban wastewater is now necessary so that the water which ends up at a final destination (lakes, rivers, sea, land) is in the best possible condition, in order not to degrade the water resources of our planet. The water that has been properly processed can be reused in ways such as:
- Farmland irrigation
- Irrigation of parks/ football fields/golf courses, open spaces in shops/industries, etc.
- Industrial activities, mainly for refrigeration
- Enrichment of groundwater, either through spreading basins or by direct infusion in the undergoing aquifer.
- Environmental/recreational use, including a number of uses other-than-drinking but associated with activities related to water, eg recreational water areas, enrichment of wetlands or enhancement of streams
- Fire extinguishing, air conditioning, toilet cleaning or construction.
- Drinking water is obtained after mixing the recovered water with raw drinking water.
Treatment of industrial wastewater
Industrial wastewater is industrial effluent generated during various industrial processes. These can take place in paint shops, slaughterhouses, canneries, dairies, etc. Processing is necessary so that the water which ends up in municipal water/ sewage companies or final recipients (lakes, rivers, sea, land) is in the best possible condition and, in accordance with environmental requirements for the disposal of industrial effluents.
The processing required in each industry depends on the quality standards of each, the final recipient or the intended use of greywater, and the available financial and technical resources.
