Resource efficient and environmental friendly wastewater treatment

Resource efficient and environmental friendly wastewater treatment

A wastewater treatment plant’s main task is to receive and treat wastewater. The treatment must also enable recycling and reuse of the wastewater content, be carried out in a resource-efficient manner and not contribute to global heating or other environmental impacts.

Wastewater treatment challenges

Many existing wastewater treatment plants are facing increasingly stringent emission requirements, lack of capacity due to increasing load, and surrounding buildings that are creeping closer. Therefore, renovations and expansions may be required, at the same time as costs for investments and operation must be reasonable.

Wastewater treatment requires resources, primarily in the form of electricity, chemicals, basins, mechanical equipment and personnel. Tougher treatment requirements to increase the quality of the treated wastewater can lead to a greater need for resources. Digitilisation and automation are important tools for reducing the need for resources, but there is still great potential in the development of new biological, physical and chemical treatment methods.

Resource-efficiency and climate impact

Resource-efficient treatment often means a lower environmental impact, but not always. Climate impact from wastewater treatment can be significant in direct emissions of nitrous oxide, methane and fossil carbon dioxide. Both measurements of emissions and system analyzes are important in order to be able to assess the environmental impact of a wastewater treatment plant.

The purpose of this focus area

The purpose of this focus area is to develop new wastewater treatment processes, but also to further develop existing processes and process combinations. The goal is resource-efficient, environmentally friendly, compact and robust wastewater treatment plants with a good working environment.
