Polishing of synthetic electroplating wastewater in microcosm upflow constructed wetlands: Metals removal mechanisms

This paper presents the study of the metals removal mechanisms in microcosm upflow constructed wetlands used for polishing of synthetic electroplating wastewater. Four types of columns were used: with and without plants and with different bed media (peat or gravel). The main design goal of the columns with peat was to promote precipitation of metals with biogenic sulfides produced by sulfate-re...

Polishing of synthetic electroplating wastewater in microcosm upflow constructed wetlands: Effect of operating conditions

This paper addresses the issue of polishing electroplating wastewater in subsurface vertical flow constructed wetland. Electroplating wastewater treatment or polishing in constructed wetlands (CWs) was studied to a very limited degree. Four types of microcosm upflow constructed wetlands were selected for the experiment based on type of bed media and the presence or absence of vegetation (Phragm...

Removal Mechanisms in Constructed Wastewater Wetlands

The use of constructed wetlands is a relatively new technology but the system is gaining popularity due to its low tech system for treating wastewater (DeBusk, 1999b).Constructed wetlands have found to be effective in treating domestic wastewater where municipalities are concerned with reducing suspended solids, organic matter, phosphorus, nitrogen, and pathogens. Constructed wetlands mimic nat...

Comparison of Different Types of Media for Nutrient Removal Efficiency in Vertical Upflow Constructed Wetlands

This study investigated the efficiency of two types of media, namely, gravels and sand for their nutrient removal capabilities from wastewater. Different levels of sand depths were also experimented for their removal efficiencies. And for this purpose three laboratory scale vertical upflow constructed wetlands (S1, S2, S3) were established at PHE Laboratory, MNIT, Jaipur. S1was filled with two ...
