The main goal of this study is to investigate the use of Water Hyacinth (WH) for the treatment and purification of dirty water, with a focus on industrial waste water. This product's primary and most important goal has been to address and conserve the environment in the most natural way possible. The item is widely available. Throughout its entire life cycle, the facility is economically feasible in terms of production and maintenance. It necessitates the least amount of human effort. It is a highly adaptable plant that can be easily grown and whose rate of development is in multiples with little care, and that too in a wide range of environmental circumstances. In the water hyacinth treatment plant, the experiment resulted in a reduction in pollutants/nutrients, odour, and colour. It is also cost effective when compared to the traditional approach of wastewater treatment in water treatment plants
