Application of Microalgae in Wastewater Treatment

Abstract

The textile industry has flourished tremendously in response to increasing customer demands for its products. This is naturally accompanied by increasing amounts of wastewater. These effluents contain high levels of synthetic dyes, detergents, stain repellents, waxes, biocides, etc. The dyes are often non-biodegradable and carcinogenic. When released into waterbodies, the intense colour apart from impairing water aesthetics drastically deters sunlight penetration thereby affecting aquatic photosynthesis. The other pollutants in the effluents are capable of giving rise to several human disorders. Treatment of the effluent before release into the environment is thus imperative, and environmental regulations have imposed definitive standards. Several physico-chemical treatment methods have been identified to help conform to these standards. The methods are however cost intensive. The use of algae in remediating textile effluents has been suggested as a cost-effective alternative. Algal biomass have demonstrated adsorption properties superior to its chemical counterparts. Some studies have even reported biomass generation in addition to effluent treatment thus inviting interesting prospects for other applications such as carbon sequestration and biofuel production. The current chapter thus discusses the possibilities and constraints of phycoremediation of textile effluents.
