Exploiting the huge potential for energy savings and resource recovery through wastewater treatment
Approximately 2 percent of the world’s total energy consumption is used for collecting and treating wastewater. Consequently, there is a huge potential for energy savings and energy recovery in wastewater treatment. Considering wastewater as a resource is a relatively new perspective. The organic content in the wastewater can be used as a resource for energy production and phosphorus can be used for fertiliser production with several advantages compared to the application of sewage sludge on agricultural land. Improving a wastewater treatment plant’s energy self-sufficiency and selling surplus energy to the grid can reduce costs for wastewater utilities. Danish wastewater utilities are therefore investing heavily in both energy efficiency and production, and the largest wastewater treatment plants are now net producers of energy.

The shift from a conventional wastewater treatment plant towards a resource recovery facility has become a priority focus in Denmark. Consequently, BIOFOS is now in the transfer process towards optimising resources from waste without compromising the environment.
A new heat pump in Copenhagen will collect energy from both wastewater and seawater and test how the energy can be used in district heating. The capacity of the heat pump corresponds to district heating for 1,100 Copenhagen households.
At Aaby and Marselisborg Wastewater Treatment Plants Aarhus Vand extract phosphorus from the wastewater and sell it as valuable fertiliser under the name PhosphorCare. In 2013, Aarhus Vand opened the first full scale demonstration plant in Denmark at Aaby Wastewater Treatment Plant to test the viability of renewable phosphate production in Denmark. Today the plant […]
Total energy renovation of the treatment plant at Egaa, just outside Aarhus, means that Aarhus Vand is setting new standards for developing treatment plants from energy guzzlers into energy producers. This has happened through entirely new technologies that exploit the green energy-production potentials in wastewater. The topping-out is a milestone in the technological development of […]
At Marselisborg Wastewater Treatment Plant we in Aarhus Vand produce 50 percent more energy than we use. By implementing energy efficient solutions and producing biogas from the sludge, we are almost able to cover the energy consumption for the whole water cycle from the groundwater extraction, to pump stations, water distribution and wastewater treatment.
The safe handling of wastewater is essential to public health. Efficient and innovative design of wastewater systems is also a basis for sustainable development. We help our customers choose the optimal financial and most energy efficient solutions within the areas of: Wastewater management Strategic planning Drainage systems Wastewater treatment Operation and maintenance Ramboll has many years […]
Enhanced demands for food production will increase the global demand for fertilisers such as phosphorus. The global sources of phosphorus are limited, and the increased demand will result in rising market prices and a global fight for control over the limited reserves emphasising the need for methods enabling phosphorus recycling. In such a market situation […]
