Beverage bottler ABC Atlas Bottling Maroc contracted Envirochemie to plan, construct and commission two Biomar biological wastewater treatment plants. The soft drink bottling plants of an internationally well-known manufacturer are located in Tangier and Oujda.
The purpose of the biological wastewater treatment plants is to ensure compliance with the Moroccan limit values for discharging treated water. Effective prevention of odour emissions is also required, since e.g. the bottler's plant in Tangier is located in the immediate vicinity of a residential area.
At both locations the project encompassed the implementation of multi-stage biological wastewater treatment plants where wastewater is treated anaerobically using the Biomar ASBx process and aerobically using the Biomar OBR process. Since 2012 treatment quantities have ranged from 700 m³ wastewater/day at the location in Tangier to 800 m³ wastewater/day at the location in Oujda.
An additional benefit for the customer is the biogas generated during biological wastewater treatment. This enables an energy yield of more than 3,500 KW per day, resulting in a noticeable reduction of primary energy consumption.
