Three phases
The wastewater treatment system for Pronaca’s Pifo facility has three main phases. Firstly, pre-treatment by the Dissolved Air Flotation unit efficiently pushes fat and other non-dissolved substances to the surface for removal. Secondly, biological treatment uses bacteria to decompose dissolved substances such as carbon and nitrogen pollution. And finally, the BioFlot system separates sludge and water. Given the limited space of the Pifo site, Marel’s BioFlot system was the best option in this third phase to fit into the available area. This flotation process happens in a basin with surface aeration and brings the separated sludge to the surface to scrape it off. While a settling process would require a relatively big biological reactor basin and a circular clarifier, BioFlot needs a smaller biological reactor basin due to a higher activated sludge concentration. The cleaned water passes through a final disinfection stage before being safely released into the nearby river.
Esteban Flores is pleased with how Pifo’s wastewater system operates: “Marel’s treatment system is reliable and guarantees compliance with the highest local and international standards. Thanks to their efficient and versatile technology, their wastewater solutions add real value to our operations."
About Pronaca
In 1974, Pronaca’s original brand Indaves was established to produce eggs. With the launch of Gustadina table oils in 1986, the diversification into other foods (poultry, pork, beef, fish, plant-based, pet food) began. This has grown into today’s huge number of brands under the Pronaca umbrella such as Mr. Pollo, Mr. Pavo, La Estancia, and Mr.Cook ready-to-heat frozen products.
