APPARATUS FOR DOSING POWDERED OR GRANULATED ADDITIVES IN WATER WORKS, NAMELY SWIMMING POOLS

摘要

An apparatus for dosing a granulated or powdered additive in the water of a water works, comprising a dosing assembly (10) with a water collecting tank (9) hydraulically connected to at least one inflow (20, 21) of unmixed water and to at least one outflow of additive-mixed water (33) to the works. Unmixed water is tapped through a duct (41) from an inflow and fed to a substantially tubular manifold (18), upwardly connected to tank (19). The additive is delivered into manifold (18) by delivery means (11, 14) placed thereabove, whereby within manifold (18) the additive mixes with water tapped from the inflow through duct (41) and additive-mixed water discharges into collecting tank (19). The dosing of a pH-reducing agent into tank (19) is also provided. Electronic means control delivery means (11, 14), the pH-reducing agent dosing means and the feeding of the water to the works.
