It is generally recognized that microalgae play an important role in self-purification of natural waters. The use of microalgae for tertiary wastewater treatment, CO2 elimination, and biomass production for sustainable valuable sources as biofuels, pharmaceuticals, health foods, carotenoids, dyes, fine chemicals, and other applications is a feasible option. Microalgae have a vast industrial and economic potential. The secondarily treated sewages contained ammonium, nitrates, phosphates, potassium salts, organic matter, inorganic carbon and other micronutrients. The values...
