摘要： A water filtration inlet comprises one or several drain pipes (1) of a limited length fitted inside a frame (2) with transport loops (3). The drain pipes are closed at one end, and open at the other end, which latter end is connected to a header box (4) from which there is a water outlet (5) for the filtered water. The water filtration inlet is especially for use of taking in sea water for aquaculture and demineralization plants where water is being turned into fresh water.

摘要： Process for making use of groundwater collected by drilling, employing at least two successive levels of pumping (2, 7) of the water before sending it to a treatment factory, specifically a primary pumping (2) in which water is pumped out of a sector where the groundwater is rapidly recharged and where it benefits from a natural filtration through the earth, the water produced by this first pumping being directed into an artificial open-air re-feeder basin (5) from where, as it filters down to the aquifer, it undergoes filtration for a second time in an oxidizing aerated medium, and a secondary pumping (7) performed in the vicinity of the re-feeder basin to supply the treatment factory.
