ABSTRACT
The research concentrates to treat wastewater by natural method. Wastewater treatment consumes the prospective to reduce water demand. Constructed Wetlands are a wastewater treatment method for optimizing their performance to meet treated discharge standards. These systems have progressed and effective replacement for conventional wastewater treatment. Natural wetlands act as the “kidneys of the Earth.” The demand for water has increased as the urban population, urbanization, and economic development have expanded, particularly in water-scarce regions. The Conventional wastewater treatment methods pollute environmental and many numbers of labour for their operation and maintenances, and huge construction cost. Therefore, this paper summarizes an environmentally friendly technology for treating wastewater. The main aim of the study is to reduce the carbon footprint of the environmental for wastewater treatment process. There are four phases for experimental investigations, the first phase is to optimize the ratio of materials from earlier studies with different parameters such as different filter media, different plantations and different in and outflow. In the second stage, the experimental work is carried out to find the optimal result. The third phase of research is to develop a prototype of wetland system. The fourth phase of research is involved in predicting recycling and reduction technology for solid waste generation and wastewater treatment process. Based on the research, the biological oxygen demand (BOD) was reduced by 68.5 percent, 52 percent for Chemical Oxygen Demand (COD), 79.4 percent for Total Suspended Solids (TSS), 68.5 percent for Total Dissolved Solids (TDS), 32 percent for Total Nitrogen(N), and 38.2 percent for Total Phosphorous in wastewater from the UTAS-Shinas after treatment. The efficiency of wetlands system is compared between before and after treatment of wastewater in UTAS – Shinas. The treated water can be reused in many uses, such as irrigation, showering, washing etc.
