On a commission for Novafos A/S with Krüger Veolia as the consultants, we have recently installed and started up a completely new bottom aeration system in the process tank at the Stenløse treatment plant.
We won the contract with an offer in which price and delivery time were weighted with 40 %, energy consumption with 40 %, and technology and the working environment with 20 %.
Since there was no suitable building for the installation on the site, a tailored solution was chosen, in which the fans and other installations were mounted in an insulated container.
An optimal oxygen supply is secured by means of 200 plate aerators, which are supplied with oxygen from two Kaeser rotary blowers. We have experience of impressively good results from this solution. With minimal maintenance and cleaning with formic acid, it should ensure optimal aeration in the process tank for at least the next 15 years.
