Opportunity Snapshot

Wastewater Treatment Equipment Market Growth Drivers and Impact Analysis

Tightening discharge compliance across municipal and industrial facilities

More focus is being put on nutrient removal, pathogen reduction, industrial wastewater purification and discharge into receiving waterbodies in a safe way. This is driving more demands for filtration systems, biological treatment facilities, disinfection systems, sludge treatment facilities and automated controls. The effect is mostly evident in municipalities with old facilities, as well as industries putting up their own facilities.

Rising water reuse and circular water management investments

The issue of water shortage has turned waste into a resource that needs to be recovered rather than disposed of. Industries have started using recycling systems to cut down the amount of freshwater withdrawn, while cities have started to treat wastewater for reuse, irrigation and industrial use through tertiary treatment. This provides a rationale for the need for membranes, filtration, and disinfection systems.

Modernization of aging wastewater infrastructure

Most existing treatment facilities work on the basis of treatment equipment installed many years ago, leading to a need to replace pumps, motors, clarifiers, valves, aerators, and process control equipment. The modernization processes focus on energy efficiency and automation along with storm flow fluctuations. This is an ongoing chance for equipment suppliers with a high degree of mechanical reliability and digital diagnostics.
