A Comparative Study of Vetiver Grass and Lemon Grass Using Phytoremediation Technique for Waste Water Treatment

Abstract

The increase in population led to a scarcity of water. There are lots of diseases and problems that are affecting the environment and human life. This is increasing day by day. This causes lots of hazards in our world. To treat wastewater, we have lots of methods. In spite of this, it is very expensive, not affordable to the masses, and also not properly treated; therefore, we use natural methods to treat the wastewater in a way that does not harm our environment. To avoid this situation, there is a solution: using vetiver grass and lemon grass to treat wastewater. As a result of this method, we are able to determine a number of parameters, such as pH, turbidity, conductivity, alkalinity, DO, BOD, COD, and T.T. The coliforms are analyzed to identify changes before and after treatment. With the rapid growth of urbanization and industrialization, there is a high intake of water and a great generation of wastewater. This study aims to find the most cost-effective method for wastewater treatment and compare it to the conventional method of wastewater treatment. The conventional method is not suitable in rural areas as it is highly expensive. The foundation and improvement of a healthy life through water are two of the most important fundamentals. Using vetiver and lemon grass for wastewater treatment has been proven to be a sustainable and cost-effective alternative to conventional wastewater treatment technologies. In this study, an attempt is made to find the effectiveness of vetiver grass and lemon grass in a laboratory for pollutant removal from wastewater. Various characteristics of wastewater before and after treatment have been checked to study the comparative effectiveness of these two plants. Removal efficiencies of parameters like pH, conductivity, chemical oxygen demand, biological oxygen demand, dissolved oxygen, total coliform, turbidity, and E. coli are analysed.
