Treatment of Industrial Wastewater and Its Reuse for Sustainable Agriculture Practices—A Green Concept

Abstract

Fresh water is very much essential for the survival of human beings. In recent years, water pollution issues have been the focus of increasing global concern. In developing countries, industrial sectors consuming large amount of the available fresh water for their productions. At the same time, it releases equal volume of wastewater into the environment and causes ecosystem damages. In the concept of environmental and economic sustainability, a proper wastewater management and water reuse system can help to a greater extent in development of national economy. Most of the currently used water treatment technologies are very much costly and not eco-friendly in nature. In this context, a new search for cheap and low cost wastewater treatment technology is essential. Recently, a new biocarbon technology in water and wastewater purification process is introduced in pilot scale project. The biocarbon is generated using a novel medicinal plant Tridax procumbens (Asteraceae). The characteristics of the biocarbon is unique and having good potential for the removal of inorganic and organic components in water and wastewater system. As a model trial, a saline water sample containing TDS of 3000 mg/L was introduced in the reactor system, after equilibrium time of 3 h; the concentration of outlet water was 425 mg/L. The removal of color from an industrial wastewater was performed with the initial concentration of 100 mg/L with optimum biocarbon dose of 2.5 g/100 mL. An excellent result (98.5%) of color removal is achieved in 150 min. These results suggest that, the treated waste water can be reused for sustainable agricultural practices.Please check and confirm if the author’s name and initial are correct.Corrected
