Abstract
The rational and principles of an algae-based wastewater treatment system with multiple sources of revenue are discussed in this presentation. Aft er an overview of historical references on algae-based wastewater treatment programs, a step-by-step process is described for a high quality effl uent and algal biomass with an optimized algal oil content. Th e dominant strains of algae found in wastewater ponds are discussed and a list of fi ve genera including Euglenia, Scenedesmus, Selenastrum, Chlamydomonas and Actinastrum are suggested as candidates for large-scale culturing based and their ability to strip nutrients and organic matter from wastewater, growing rapidly and producing a signifi cant level of oil. The final part of the presentation deals with Supercritical Fluid Extraction as an effi cient means of isolating algal oil and other commercially important compounds from algal biomass.
