L’Aigua residual d’origen domèstic o industrial requereix un tractament rigorós abans del seu retorn al medi ambient. Aquest tractament es realitza en instal·lacions específiques formades per diferents processos, seleccionats en funció de les característiques de l’aigua a tractar i del destí final de la mateixa.
Water, as we find it in nature, is often not directly usable for human consumption.
AREMA has different drinking water treatment and supply systems. Depending on the needs of work, AREMA provides particular solutions to municipalities, industries or small rural nuclei.
We define Regenerated Water as that which comes from wastewater treatment plants and which, once treated, is applied an additional treatment to make it suitable for a new use, with the quality required by the new application.
Regenerated water is taken into account in the overall management of resources and its uses can be diverse.
Desalination is a physical process of separating salts from an aqueous solution, with the purpose of using the fresh water produced.
Desalination water resources can have basically two sources: seawater or saline groundwater; the latter from coastal aquifers in direct or indirect contact with the sea.
The separate fractions in the decanters (primary and secondary) of the treatment plants are called sewage sludge or sludge. These are liquid, with very low concentrations of dry matter. An important part of the dry matter of sludge is organic matter.
The sludge undergoes different processes, with different purposes.
The treatment of liquid or leached waste from urban landfills, sludge treatment plants or from “Ecoparks” or “Ecological Parks” of waste, is a complex issue that requires a deep knowledge of it to be able to offer solutions with guarantees.
