Title
(EN) METHOD AND APPARATUS FOR WASHING AGRICULTURAL PRODUCTS
(FR) PROCEDE ET APPAREIL POUR LAVER LES PRODUITS AGRICOLES
Abstract
(EN)
A method and apparatus for washing agricultural products with recycled, purified water is disclosed. Contaminated wastewater is recovered in catch basin (12) and then conveyed to a sump tank (17) for storage. Water from sump tank (17) is then conveyed via lines (31 and 32), where a coagulant is added, to a first coagulation compartment (34) of a vessel (69). Purified water from compartment (34) exits into second compartment (36) of vessel (69). The further purified underflow from compartment (36) is transferred to ozone contact tank (46). Thus decontaminated water is returned to the spray nozzles of a washing station (10).

La présente invention concerne un procédé et un appareil pour laver des produits agricoles avec de l'eau recyclée et purifiée. L'eau de décharge est récupérée dans un réservoir de retenue (12) et transmise ensuite à une citerne (17) pour y être stockée. L'eau provenant de cette citerne (17) est ensuite transmise via des conduites (31) et (32), où un coagulant est ajouté, à un premier compartiment de coagulation (34) d'une cuve (69). L'eau purifiée provenant d'un compartiment (34) sort dans un deuxième compartiment (36) d'une cuve (69). Le courant de fond encore purifié provenant du compartiment (36) est transféré à une cuve de contact avec l'ozone (46). Ainsi, l'eau décontaminée est renvoyée aux buses de pulvérisation d'un poste de lavage (10).
