Technical Proposal For

Benghazi, LIBYA, New Sewage Treatment Plant in Kufiah

Design, construction and commissioning

270.000m³/day capacity, Turnkey Basis

Revision, Evaluation and recommendation for the discharge and mechanical Equipment proposed by RANHILL ENGINEERS and CONTRACTORS SDN BHD for the above New Sewage Treatment.

a. Sewage Discharge [270 MLD – 270.000m³/day]:

Recommendation

Due to the lack of data of present and future flows with respect to its design year, a present and predicted discharge figures shall be predicted based on 20 year planning period with a design life in excess of 20 years should be designed for the extended period.

b. Design Basis:

Parameters

PH Infl. 6.8-8 Effl. 5.5-9

B.O.D Infl. 400 mg/L. Effl. <20 mg/L.

C.O.D. Infl. 600 mg/L. Effl. < 50 mg/L.

S.S. Infl. 400 mg/L. Effl. < 20 mg/L.

Oil & Grease Infl. 100 mg/L. Effl. < 10 mg/L.

Phosphorus Infl. 4 mg/L. Effl. < 2 mg/L.

Ammonia nitrogen Infl. 40 mg/L. Effl. < 15 mg/L.

c. Treatment process system:

Dissolved Air Flotation Technology.

Activated sludge system.

Aerobic sludge Digester System.

Fully PLC based.

Fully automatic treatment System.

And the component parts of the plant:

Primary Coarse screen.
