Challenge for Modern WWTP
In many countries the wastewater treatment plant (WWTP) infrastructure is ageing and therefore often struggles to maintain the consistent treatment rate and has no capacity to receive and deal with constantly increasing wastewater treatment demand, tightening consents and rapidly rising pressure to achieve compliance.

The global population growth in combination with diminishing land availability excludes large footprint retrofit upgrades. The list of constraints in upgrading the WWTP and/or building a new facility is even longer. Minimising capital expenditure, reducing operational expenditure with the reduction of energy requirements add even more constraints on the wastewater treatment technology and its application in final WWTP design.

The question thus becomes: how can you better manage and upgrade existing plants without adding these costs? The aerial view of a typical wastewater treatment plant is shown in Figure 1 – as with most there is not much space to work with.
