Industrial effluents enter the pond system after receiving primary treatment at each fishery plant. They are first introduced into an anaerobic lagoon which, by overflowing, transports them to two aerobic basins, where they complete the mineralization of organic matter. The aerobic ponds have eight 7HP and eight 2HP aerators. The treated liquid ends up in a final disposal bowl, where it evaporates and its subsequent reuse in the irrigation of halogenated plants is planned.
