In India, textile industry is the eldest and major manufacturing industry in the country. Gradually increasing demand of products causes increase in wastewater generation. Textile wastewater is a combination of types of dyes used and additives such as oxidizing agents, surfactants, salts, heavy metals, dispersing agents and finishing agents comprising compounds that are persistent and lethal. Physico-chemical treatment processes of textile wastewater such as chemical coagulation processes are cost effective but lead in significant sludge volume generation. Such sludge production requires appropriate treatment and disposal. Natural coagulants be naturally occurring low cost products, biodegradable and so environment friendly. This study is based on the relevance of Banana Stem Pith Juice as an organic coagulant for textile wastewater treatment and their comparison for treatment efficiency. Jar tests were conducted using varying dosages and pH adjustment of raw wastewater. Appropriate pH and dosage of the natural coagulant was observed to be 4 and 1000mg/L respectively. Coagulant Banana Pith Juice showed results of treatment efficiency for parameters COD, BOD, TS and TSS as 14.04%, 13.12%, 18.52% and 40.37% respectively.
