Construction of an Energy Positive WWTP for Aarhus Water in Denmark

After winning the prestigious Aarhus Water Ideas Competition for innovative, energy-efficient technology two years ago, Salsnes Filter has now brought this win to contract. Collaborating with Danish engineering company EnviDan, they are installing a Salsnes Filter system at the Egaa WWTP in Aarhus, Denmark. Construction is now underway with plant start-up scheduled for spring 2016.

Salsnes Filter was selected for this project because of their well-documented and proven technology for carbon harvesting through TSS removal in primary treatment. EnviDan was chosen for their innovative approach and design using the Annamox anaerobic biological treatment for cold waters (EssDe). The objective is to produce 150% of the energy needed to run the plant. 

A single module consisting of eight SFK units will be provided for primary treatment. The system will maximize carbon harvesting and is designed for polymer pretreatment to enhance solids separation.

Salsnes Filter is extremely pleased to have been chosen for this project and to be able to continue enhancing wastewater treatment in facilities around the globe.

Salsnes Filter System Part of Upgrade Plan to Double Plant Capacity

Salsnes Filter in collaboration with Biowater Technology has won a project to install a Salsnes Filter biowaterLogosystem along with biofilters at the Saulekilen Sewage Plant in Arendal, Norway. The upgrades will almost double plant capacity from 45000 p.e. to 80000 p.e.

The Salsnes Filter system will perform primary solids separation to reduce loadings on the downstream biological treatment process. There are future plans to utilize the sludge collected by the system to produce biogas for internal energy production.

Due to its small physical footprint, the Salsnes Filter system will fit into Saulekilen’s existing building. It will be installed on top of the biofilters so that former basins can be available for new bioreactors and clarification of biological solids by Dissolved Air Flotation.

Equipment will be installed as the Plant continues to operate and is set to be complete in April 2015.
