Feasibility studies on combined constructed wetland for the treatment of household greywater using phytoremediation

Abstract

Water scarcity has recently become a major issue in arid and semi newlinearid nations like India. Due to its rapid industrialization and population growth, newlineIndia is experiencing a water shortage because it only possesses 5% of the newlineworld s water resources. To address the issue, India must look at other water newlinesources, which might include rainwater collection, wastewater and greywater newlinerecycling, and salinity. The primary goal of this research is to conserve and newlinecleanse water. Greywater is the main source for this study. The washroom, newlinelaundry, and bath water were used to create the greywater. In this thesis, these newlinethree types of water were collected and cleaned utilizing constructed wetland newlineand phytoremediation. This constructed wetland was divided into two newlinecategories, horizontal and vertical. newlineThe term horizontal constructed wetland refers to a basin in which newlinewastewater runs horizontally through which the filter material removes newlineparticles and microorganisms break down the organics, and water flows from newlineup to down in a vertically constructed wetland. For this study, five numbers of newlinehorizontal and vertical tanks that varied in length, width, and height were newlineconnected with retention and collection tanks using main and subline pipes newlinewere used to design the greywater treatment unit, along with the chosen newlinephytoremediation plant samplings namely Typha angustifolia, Phragmites newlineaustralis, Canna Indica, Cyperus rotundus, and Cyperus pangorei. The purpose newlineof this experiment is to evaluate the strength and effectiveness of the chosen newlineplants for the treatment of greywater with different Hydraulic Retention time newlineand Hydraulic Loading Rates. newline
