Abstract
In recent years, Raceway reactors are becoming popular because of its less cost of construction and mixing energy requirements. The raceways are considered as a most practicable technology for the microalgal energy generation. The raceway pond is 0.25-0.30 m deep closed recirculation canal and algal broth is continuously mixed by the paddlewheel. Paddlewheels are considered as the most efficient technique for creating flow in raceways. Dead zone development is eliminated by deflector baffles. Open raceway ponds are frequently employed for the commercial production of algal biomass. Even though the raceway method of production of algae is slightly costlier than other algal mass culture methods, it finds its place in production of biomass for Biodiesel, Lipids, Pigments and carotenoids, neutraceutical industries.
