URBAN WASTEWATER TREATMENT USING SEQUENCING BATCH REACTOR
Keywords:

The treatment of wastewater is important for protecting the water resources. The criteria for wastewater
effluent discharge is the driving force for implementing new technological processes that will meet the required
standards and regulations. In this paper we investigate the work of a pilot-scale sequencing batch reactor (SBR) used
for treatment of wastewater from an urban commercial object. The SBR has a total volume of 48 m3 and is designed
for treatment of 80 m3/day wastewater from the airport terminal in Skopje. The aim of this experiment was to see the
efficiency of the pilot SBR and the results of the treated wastewater. The SBR reactor is working in fallowing order:
fill, react, settle, draw and period of waiting for the next cycle. Chemical oxygen demand (COD), fats and grease,
total suspended solids (TSS) were measured as target parameters in the treatment. The measured SBR effluent
concentrations were below the needed local standards for effluent discharge. The results indicated that the SBR
technology is suitable for wastewater treatment in commercial areas of Skopje, with high potential of reusability for
sustainable wastewater management.
