Process: Activated sludge plant with extended aeration and floating/ moving fine bubble aeration according to BIOWORKS® design. Tertiary treatment with slow sandfilters.
The waste water treatment plant for 6th of October City is located approximately 25 km west of Cairo and treats the waste water of the 6th of October city settlement. The project was realized under the consortium ORASCOM / BIOWORKS and went into full operation in June 2014. It is separated in 3 parallel treatment lines, each with a capacity of 33.333 m3/day. The scope of BIOWORKS included the complete design works and supply and installation of the electromechanical equipment as well as the sealing of the basins with HDPE liner. The plant comprises also full tertiary treatment with slow sand filters, these are one of the largest units ever built worlwide. The effluent quality is excellent, reaching outlet values of BOD/TSS < 12/15 mg/l after secondary and < 2/2 mg/l after tertiary treatment. The treated water is used for irrigation, and during the course of the last 3 years, a large greenbelt could be created in the desert.
