Abstract
For a healthy living the foremost prerequisite is a clean environment ensuring sustainable treatment along with safe and suitable disposal of the wastewater call for major attention. Being one of the most enormously used natural resources on earth by any living being is water and it will not be an exaggeration stating that a huge quantity of wastewater is generated by any budding community. Not only surface but even pollution of ground water can be caused by raw untreated disposal of wastewater into the environment. Certainly this brings in more serious issue as it gets highly unsafe with the elevating levels of pollution. Eventually numerous developments are coming into picture in the field of wastewater treatment. Moreover, these approaches are coming up with improved effective pollutant removal in addition to exploring sustainable eco-friendly approaches for pollutant removal. The two important red flags on the world map are textile industries and river âGangesâ making the Varanasi city significant round the globe known for its âBanarasi Sareesâ and âHoly pilgrimage riverâ are unfortunately seeking serious immediate help. Various steps used by these manufacturers such as dyeing, fabricating, texturing and finishing stages give out high quantity of chemicals, like binders, acids and salts, etc., undoubtedly adding toxicity to the ecosystem. Here degradation and treatment of the certain harsh color imparting chemicals are being studied subjecting them to two species of microalgae (Chlorella pyrenoidosa and Scenedesmus obliquus). Nevertheless different modes of biological, chemical and physical methods have been used for textile wastewater treatments, however using microalgae which are easily grown can add upto an economical and eco-friendly approach.
