GEC Has Contracted Texas-Based Headworks BIO to Retrofit a Wastewater Treatment Plant

The General Egyptian Company for Buildings (GEC) in Cairo has contracted Texas-based Headworks BIO to retrofit a wastewater treatment plant in Alexandria. The Mubarak facility in Alexandria was initially designed to treat 4, 000 m3/day and was commissioned in 2001. However, the plant was taken out of service in 2009 after suffering from membrane fouling challenges. Headworks BIO was asked to review the performance of the existing plant and evaluate the options available for refurbishment. The proposed system involves retrofitting MBR (Membrane Bioreactor) aeration tanks with a Moving Bed Biofilm Reactor (MBBR) to treat 4, 000 m3/day and convert the remaining volume into a secondary clarifier. The retrofit will help the facility produce a consistent effluent quality of 50: 80: 50 mg/L for BOD: COD: TSS. The biological treatment process will remove the influent BOD to meet the required effluent target and require minimal maintenance because each piece of media self-maintains an optimum level of productive biofilm, according to the company.
