<p>The system has a filtration block (1) with an aeraulic decompression passage permitting to evacuate air from a storage tank (31) during its filling. The passage is integrated to the block. An overflow pipe (35) connects the filtration block to a water borne sewage system (36). The pipe has an anti-return valve (37) that allows entry of an exiting air flow, during filling of the tank. Water pumped in the tank is guided by a pumping pipe (38). The block has a tank closed by a cover, and a filtering element, where the tank of the block has a water inlet orifice and an overflow orifice. An independent claim is also included for a method for manufacturing a filtration block.</p> |
