2.5. Water quality characterization
Water quality in terms of physicochemical properties and inorganic contaminants was assessed in order to evaluate the reliability
of the plant operation. Specifically, pH, electric conductivity, total
suspended solids (TSS), turbidity and temperature were determined for each sample collected.
3. Results and discussion
In order to evaluate the behavior of the ECs in the DWTP, first
their occurrence in the raw water (Llobregat River) was determined. Secondly, EC removal behavior was evaluated for all the
units available in the DWTP. Finally, ECs concentrations present in
the influent of the DWTP and in the product of the EDR process were
evaluated and compared in order to determine the cumulative EC
removal of the whole DWTP processes.
