Ferric, Manganese and Latex removal for Chiquita banana packing plant
Company : Chiquita
Location : Panama
Year : 2003
Description : Supply clean water for a Banana Packing plant
Goal : Ferric, Manganese and Latex Removal from delaxing pools
Capacity : 40 m3/hr
Water Source: A private deep well
The Problems :
- The plant’s well water contained Ferric and Manganese.
- The incoming bananas oozed Latex from the cut.
- The combination of the above turned the water color to purple and stained the bananas.
- Water turbidity was above the maximum allowable level.
- Water polluted with germs and fecal coliforms.
- Wastewater were not recycled and created ecological problems downstream.
Technical Solution :
The following processes were carried out:
- Side-stream circulation: Screen Filtration with automatic back wash.
- Oxidation of Ferric, Manganese and Latex into a lamella reactor: Implementing Hydrogen Peroxide with redox control.
- Coagulant dosing in order to agglomerate the oxidized fine particles into bigger flocs.
- Media Filtration: Catalytic Media Filters – implementing AFM®.
