Purification system for wastewater coming from fruit and vegetable processing plants and phytosanitary treatments in the field

This invention, as stated in the heading to this descriptive report, concerns a purification system for wastewater coming from fruit and vegetable processing plants and phytosanitary treatment in the field, with which notable relevant and advantageous characteristics are contributed compared to present conventional purification systems. Said equipment include a tank-filter () in which a pretreatment stage is carried out. The tank () is a decanter to which a flocculant that is uniformly mixed with an agitator () can be added. The sludge is removed by delivering it to a filter bag (). The permeates are then fed to a collecting tank () and pumped to the same tank () receiving the clarified waters. The permeates are then decanted from said tank () through a safety filter () to a battery of activated carbon columns () where they arm purified by adsorption until the established threshold values have been reached. In another embodiment, the reservoir-filter () is a polypropylene bag filter with diatomaceous earth, wherein the liquid passes directly to the decanting tank and is then pumped to the battery of activated carbon columns ().
