Title: Assessment and Redesign of Soba Activated Sludge Treatment Plant (Biolac – wox)
Author: Idris, Nuha Abdel Latif Abdel Karim
Abstract: Soba wastewater treatment plant was built in 2004 to serve Khartoum town instead of the old one (Stabilization Ponds). The new one is a type of activated sludge process which is called Biolac –wox. The plant was operated in 2009 for about 45 days. During the operation many problems happened and the plant was out of operation since that time .The objective of this research is to study the Biolac system to find out the problems that led to stop the operation and to suggest measures to solve them. The methodology adopted in the study comprised of site visits, study the reports to recognize the problems and to review the design of Soba Biolac – wox that done by Turkish company AKM. Accordingly two alternatives are suggested to resolve the problems. Alternative one suggested inclusion of addition treatment units (screen, grit chamber, primary clarifier, sludge digesters and drying beds). Alternative two suggested utilizing the existing stabilization ponds as primary and secondary treatment and the Biolac as a tertiary treatment. This option needs pumping station to collect the effluent from the ponds and to pump it to the Biolac through a rising main, and to use the existing dewatering machine to dry the sludge. The result in general showed that option two is better than option one because there is less utilization of mechanical components and accordingly minimum operation and maintenance cost. Effluent quality of option two was also better than option one.
