Abstract

A parametric method was used to study the removal efficiency of both laboratory and high-rate oxidation pondgrown Scenedesmus obliquus from dilute solutions by use of high gradient magnetic filtration. The removal was accomplished by coadsorbing the algae and magnetite in the presence of ferric chloride and by placing the mixture for a given residence time in a magnetic filter. Both for the laboratory and pondgrown algae, excellent chlorophyll removals (>90%) were observed for small residence times, low magnetic fields, and reasonable flocculant dosages.
