Abstract

Nutrients Removal Efficiency Assessment of Constructed Wetland for the Rural Domestic Wastewater Growing Distinct Species of Vegetation

Highlights

  • Water is an essential environmental factor to maintain the food supply and productive environment for the survival of human beings and other living organisms

  • The efficiency for NO3-N and NH4-N achieved by Mustard, Celery and Watercress was 79.89%, 71.95%, 80.95% and 93.14%, 77.15%, 86.69%, respectively (Figures 5 and 6), while the removal efficiency for total suspended solids (TSS) by all these three species of plants i.e., Mustard, Celery and Watercress was 70.77%, 75.39% and 81.94%, respectively (Figure 6)

  • The recent study presented the effect of three different vegetation plants and media substrate in horizontal subsurface flow constructed wetland for the removal of pollutants in rural domestic wastewater using horizontal subsurface flow constructed wetland

Summary

Introduction

Water is an essential environmental factor to maintain the food supply and productive environment for the survival of human beings and other living organisms. More than 90% of infectious diseases in developing countries are caused and transmitted to human beings through polluted water [1]. CWs are artificially designed systems consisting of medium like soil, sand and gravels and planted by plants tolerant to saturated environmental conditions [6], which offer efficient and attractive pollutants removal efficiency through physical, chemical, and biological mechanisms. Many of contaminants such as pathogens, organic materials, nutrients, and toxic heavy metals can be removed and minimized with the help of Constructed wetlands through filtration, sedimentation, coagulation, adsorption, plant uptakes and microbial transformation
