Yüksel
Construction Co., as a member of the "PNW - Cegeleg AEG-Brochier (Germany)
and Yüksel Construction Co., Consortium” carried out the construction
of all functional and dys-functional structures, site piping works, site access
roads, site and landscaping works of plant which is located on a total area
of 182 ha. Plant, designed according to the target years of 2002, 2010 and
2025, was constructed for the target year of 2025 for the inlet, preliminary
treatment, overflow and by-pass systems, for the target year of 2010 for the
treatment process units and for the target year of 2002 for the sludge treatment
units.
Treatment type applied in the plant is the biological treatment defined
as conventional activated sludge method. For the raw sludge and excess activated
sludge treatments, anaerobic sludge digestion method is being used. Eight
cylindirical post-tensioned reinforced concrete anaerobic reactors with a
total volume of 90,000 m³ were constructed for sludge treatment. The
approximate total water containment capacity of process structures constructed
within the scope of plant was 500,000 m³. Around 70% of energy requirement
of the plant, which has a total 10 MW installed power capacity, was recovered
from biogas resulting from sludge digestion process. Digested sludge, obtained
as a side product, is turned to cake form and is used for the enrichment of
soil in the agricultural areas.
