Resumen
Drinking Water Treatment Plants generate residual streams that claim for an efficient
management, in a way that it’s given proper treatment and destination, both
accordingly to the present regulatory instruments, bringing solutions that generate the
least possible impacts for the environment and human health. In this context, there is
a noticeable gap regarding studies that correlate an eventual DWTP residual stream
with its operational parameters. Thus, the accomplishment of a qualitative and
quantitative characterization for the residual stream generated by a full-scale direct
filtration DWTP allows the gathered results and subsequent generated data to be
reference to correlated studies about the residuals generation in sceneries with such
technical, technological and climatic similarities. The study presents the physicalchemical analysis results from the generated residual stream at the qualitative
characterization section, such as translates the forthcoming implications based on the
composition of thickened sludge layer samples from the bottom of a sedimentation
lagoon, operated for decades at the DWTP facilities. The quantitative characterization
data supplies the qualitative one and amplifies the various possibilities for evaluation
of technical feasibility of the steps involved in the DWTP residual stream generation
and treatment. The current research demonstrates through the quali-quantitative
characterization that it’s possible to correlate physical-chemical parameters from
generated residuals to the DWTP operational parameters, extending comprehension
of the evaluated scenario and proposing adjustments and improvements that could
bring technical, financial, sanitary and environmental gains and benefits. In this
respect, the research reveals the greatest contribution that such a proposal of
characterization might bring as valuable scientific material for more specific upcoming
studies.
