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 in collaboration with Biowater Technology has won a project to install a Salsnes Filter system 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.

On August 21st, the Magnus Mitbø educational award for academic excellence was presented to M.Sc Michael Nilan (third from right) by the Norwegian Engineers and Managers Association (FLT). The award was presented for work he did in completing his master’s thesis, entitled “Microalgae Harvesting Using Salsnes Filter Technology,” at the University of Stavanger, Norway. After thorough consideration, the Magnus Mitbø educational award is presented by professionals from the industry and the academic world in recognition of exceptional educational achievement.

Mr. Nilan’s master’s thesis dealt with improving the algae harvesting process to be considerably more efficient and cost effective through the use of Salsnes Filter Technology. The harvesting process is comprised of three crucial stages: 1) particle separation, 2) thickening and, 3) dewatering. In addition to extensive literature research, Mr. Nilan contributed to the testing and development of this state of the art technology at a wastewater treatment plant in Spain. The work he did, performed in connection with his master studies, was done as part of an international consortium research project co-funded by the EU and organized by Salsnes Filter.

Salsnes Filter is one of three winners of Denmark’s Aarhus Water International Ideas Competition. This competition is the first of its kind in Denmark and enlisted for innovative ideas on how to build future energy-producing wastewater treatment plants. 63 ideas from eight countries were submitted in three categories; 1) high feasibility, 2) long-term energy potential and 3) originality.

On November 5, the three best ideas were awarded 25, 000 kr at a well-attended event at ARoS (The Aarhus Kunstmuseum art museum). Salsnes Filter won in the high feasibility category with our “Salsnes Waste to Energy” submission. The selection committee saw it as the most realistic and proven idea documented scientifically and presented by a company with proven engineering and implemention abilities. The winners in the other two categories were Envidan and GXN.

Ivar Solvi, Manager of Business Development (second from right) explains that, “Our submission summarizes all we can do with a Salsnes Filter system to help build compact and low energy consuming plants, focusing on the integration of processes and early solids separation to harvest energy rich solids.”

The competition was created by Aarhus Water, a large inter-municipal company responsible for water and sewage in the Aarhus Municipality of Denmark. Wastewater treatment plants can be large consumers of energy, and Aarhus Water’s vision is to turn these plants into modern, energy-producing facilities that are both self-sufficient and even provide green energy to the grid.

The competition is acting as a non-traditional procurement process for the refurbishment of one of their WWTPs. The three winners will tender their equipment for the plant that is dimensioned for approximately 127 000 PE and set for completion in 2016.

Ivar comments, “We are sincerely grateful to win this award because it confirms for us that we are moving in the right direction with our product innovation and our research. We are very excited about the potential to work with the other two winners and Aarhus Water to implement our ideas.”
