Abstract


Fresh drinking water is certainly essential for human survival, but water-related illnesses are the most common health threat in the world. Industrial sectors consuming most of the available fresh water for their productions. It releases equal amount of wastewater into the environment and causes ecosystem damages. Existing desalination and water treatment technologies are very much costly and not eco-friendly in nature. In this context, a new search for cheap and low cost water purification technology is essential. Recently, we introduced new biocarbon technology in water purification process. The biocarbon is generated using a novel medicinal plant Marigold (Tagetes spp. – Asteraceae). The characteristics of the biocarbon is unique and having good potential for the removal of salts and organic components in water. As a marker trial, a brine solution of 3000 mg/L was introduced in the reactor system, after equilibrium time of 3hrs; the concentration of outlet water is 450mg/L. The removal of color from an industrial wastewater was performed with the initial concentration of 300mg/L with optimum biocarbon dose of 2.5g/100mL. An excellent result (97.5 %) of color removal is achieved in 150min. These results suggest that, the treated water can be reused for various purposes in industries and in agricultural development.
