A major food processor and food supplier lo airline companies was out of compliance due to the failure of their wastewater treatment system to perform effectively in reducing the contaminants and meet discharge requirements. They needed to deal with their wastewater efficiently and cost-effectively, and ultimately achieve compliance with the authorities discharge standards.
Hydrocal evaluated their problem and found that the main issue was that the contaminants in the wastewater varied greatly within one day and also from day to day. Their wastewater was generated from the washing and disinfecting of fruits and vegetables and the processing of breads, meats, fruits, vegetables, fried foods, dairy products and beverages. Furthermore, the processing and production schedule changed daily according to the various airline menus. In addition, they had very high levels of oils and grease, as well as surfactants and detergents, resulting from the washing and disinfecting of kitchenware.
