Shafdan Anarobic Digesters

The Shafdan WWTP treats approximately 400,000 cubic meters per day of municipal wastewater, serving a population equivalent of 2.5 million, and is designed for biological nutrient removal (BNR).

In accordance with a decision made several years ago, the Shafdan must stop the flow of sludge into the sea and implement a land-based biosolids disposal solution. The solution that was decided upon is based on anaerobic stabilization of the sludge in a manner that will enable its use in agriculture.

The principal components of the new Anaerobic Digesters facility plant include:

• Screening of the raw sludge (primary and waste activated).
• Thermophilic anaerobic digestion.
• Utilization of cogeneration units to produce electricity and hot water from the biogas produced in the digestion process.
• Treatment of all potential sources of odor using suitable systems

Balasha-Jalon has prepared the detailed design of the Anaerobic Digesters Facility. The services included   architectural, civil, mechanical electrical, control engineering, and general supervision of construction.
