dc.description.abstract | The focus of this thesis is optimization of the wastewater treatment plant, SART owned by SAR AS.
Based on an evaluation of the present treatment condition, capacity and limitations,
performance of the plant has been evaluated, with the objective of proposing optimizations in terms
of increasing capacity of the plant.
The wastewater treatment plant is designed as a conventional activated sludge plant, but is currently
operated as a CFSTR process. Mass
balance analysis of the plant
has been
done accordingly.
Experimental analysis of the wastewater
has shown
that the received wastewater is primarily
composed of readily biodegradable COD.
Effluent wastewater analysis has shown that the water
still contain
s biodegradable COD, indicating that the treatment process can be optimized further.
The performance of the plant has been determined in terms of COD removal and showed an average
COD removal of 53% and an average dissolved COD removal of 83%. The low perc
entage of total
COD removal has been found to be a result of high biomass content in the effluent.
Increasing the plant capacity in terms of flow,
has been
shown not to be feasible when operating the
plant as a CFSTR process.
Operating the plant as an activated sludge plant by recirculating and wasting sludge
has been
proposed as an option to
increase COD removal efficiency and to
increase the plant capacity. | nb_NO |
