Abstract

Wastewaters from agro-industrial and industrial sources have significant organic matter contents, and some also contain oil and grease, heavy metals and toxic chemicals. Limits have been set for pollutants, especially wastewaters, entering water bodies. Conventional methods of treatment generally require large inputs of energy, large areas of land, and high operation and maintenance costs. Microalgae biomass offers an alternative treatment approach that removes nutrients and other pollutants, such as heavy metals, nitrogen compounds and harmful chemicals. Microalgae harvested after wastewater treatment can be used as value-added products because the microalgae is rich in carbohydrates, proteins and lipids. This paper presents the types of treatment processes, current application of microalgae and high-value products derived from microalgae used in wastewater treatment processes.
