Resumo(s)
The purpose of this project was to conduct a survey for the established measureable
parameters of Guia WWTP’s operations, focusing on the sludge treatment process and analyse the
sewage sludge management and recycling model, aiming to an idealized sustainable one based upon
viable economical and financial solutions.
According to values contained in the most representative operational efficiency of sludge
treatment and production parameters, alternative options to the currently used disposal site by the
Guia WWTP for the disposal sewage sludge were presented and debated.
Moreover, it is considered a perspective of optimization, namely, for the waste management
process final phase (purified sludge), according to the possibility of the implementation of the
treatment techniques presently recognized and efficiently applied, though, considering sizing and
exploitation particularities of the concerning facilities.
However, the used methodology including an extensive literature review, allowed a systemic
qualitative screening of the produced sewage sludge at the WWTP, technical searching and relevant
statistical data analysis allowed the systemic trace/pursue of the quantitative and qualitative markers
on the generated sludge.
The associated costs projected estimation culminated in an option ranking according to each
technical-economical performance criteria, abiding to the legal requirements and suitable to the
WWTP’s installed operating capacity.
