Title
(EN) INTERMITTENT SPRAY SYSTEM FOR WATER TREATMENT
(FR) SYSTEME DE PULVERISATION INTERMITTENTE POUR TRAITEMENT DE L'EAU
Abstract
(EN)
Swimming pool or drinking water is chlorinated by the use of an intermittent spray-type chlorinator assembly (36). The chlorinator assembly (36) includes a chamber (42) for holding a quantity of solid dry chlorinating chemical (68), typically in the form of briquettes or pellets. Water spray impacts, abrades, and dissolves the briquettes (68) and the chemical-water mixture falls into a chamber (58) below the spray and is evacuated therefrom through discharge/check valve assembly (78) to a return line that leads back to the source of the water being chlorinated.
(FR)
Cette invention concerne un ensemble chlorateur à pulvérisation intermittente (36) destiné au traitement d'eau de piscine ou d'eau potable, L'ensemble chlorateur (36) comprend une chambre (42) renfermant une certaine quantité de produit chimique chloré solide sec (68), en général sous forme de briquettes ou de pastilles. Le jet d'eau frappe, abrase et dissout les briquettes (68); le mélange d'eau et de produit chimique étant recueilli dans une chambre (58) sous le jet d'eau. De là, ce mélange traverse un ensemble de soupape de décharge/anti-retour (78), puis est réacheminé via une canalisation de retour jusqu'à la source d'eau à chlorer.
