Aeration Machine for Deep Waters of the Baltic

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
Backgrund
Dissolved phosphor which has been released from the Baltic’s bottom sediment due to insufficient dissolved oxygen in the deep sea waters contributes towards increased algal bloom. Long term solutions for solving the Baltics environment are closely related to controlling the use of fertilisers within agriculture and improving waste water treatment plants. However, the phosphor that has already been spread to the Baltic has to be dealt with. There are several studies from different institutions looking into ways of oxygenating the deep water regions of the Baltic. ITT Water & Wastewater (W&WW) would like to study different concepts for providing this oxygenation. The dominating principle is to transport water nearer the surface that contains dissolved oxygen to deeper regions, i.e. develop some form of “pump”. W&WW has pertinent knowledge within this technology and would like to optimise a concept.

Deliverable
Develop a machine concept for oxygenating the deeper regions of the Baltic. Concept development contains use of both fluid dynamics and mechanical engineering. An important result is to decide the optimum way of powering this “pump” and to define the principles for transporting oxygen to the sea floor.

The proposed thesis work might include: Literature survey, concept generation, concept evaluation, prototype design and construction, prototype laboratory testing, documentation.
