Upgrading Wastewater Treatment Performance
9. Concluding Remarks • It is not always possible to fully utilise previously built facilities in updating since these were not included in the overall reconstruction. • It is recommended to take advantage of reduced volumes of wastewater and the resulting redundant capacity of tank volumes. • Newly constructed civil structures are those that replace structures with insufficient volumes (activation tanks), or unsuitable shapes or sizes (secondary clarifiers). • Application of the traditional systems R-D-N and R-AN-D-N, as well as the new application of the circulating activated sludge process with combined aeration as the oxic stage. The main reason is the possibility of a high degree of oxygen transfer regulation. • When changing the layout of a WWTP, a proper design of the hydraulic profile of the WWTP is a difficult task. It is necessary to perform detailed calculations and this problem must not be underestimated. • Despite some repeatability, each reconstruction of a WWTP is an original job and must be dealt with specifically both in terms of calculations and the technical solutions themselves.
