FEMAK

FEMAK is the abbreviation for a mobile micro-algae culture facility (=MAK) for research and development (= R&D) purposes.

At the site of the wastewater treatment plant in Plön it will be demonstrated how freshwater microalgae cultivation can be coupled with water remediation and wastewater treatment.

A microalgae bioreactor made of closed glass - tube module systems uses natural light for effective algae production. The system is operated with effluent water from the Plön wastewater treatment plant and is enriched with oxygen by the growth of the biomass. Excess nutrients (mainly phosphorus and nitrogen) are specifically reduced and only pure, oxygen-enriched water is returned to Kleiner Plöner See. The extent to which this measurably benefits water quality is part of the extensive monitoring of results.

The influx of the microalgae-remediated water into the lake's ecosystem should result in a reduction of foul gas formation, improved mixing of "barrier layers" and reduced phosphate re-suspension. If the research project is successfully implemented, the model could be transferred for remediation purposes of many species.
