Abstract
Micro-algae, especially Chlorella vulgaris, produce a range of high-va lue substances and the biomass itself is used for purposes such as fee ding in aquaculture. A lamellar settler was designed and built. Its su itability as a low-cost alternative to separate C, vulgaris was invest igated. The settler operated semicontinuously in a laboratory photorea ctor plant (total volume 9 l). A clearing of 30%-35% and a 50% increas e in harvest outflow concentration were observed. The scaled up data f or design and construction of a settler for a 200-1 production plant w ere elaborated.
