Pb Removal Using Mixed Substrates in a Constructed Laboratory-Scale Unvegetated Vertical Subsurface-Flow Wetland
In this study, five mixed substrates – SSFGF, FSSGF, FSSFF, FSSFG, and FSFGF – consisting of fly ash, sludge, soil, fine cinder, gravels, and fine sand, were made in order to test the removal effect of lead. Multiple comparisons and analysis of variance were used to analyze physicochemical properties and the removal efficiency of lead. The test results showed that for five substrates, the efflu...
متن کاملA Subsurface Upflow Wetland System for Removal of Nutrients and Pathogens in On-Site Sewage Treatment and Disposal Systems
On-site sewage treatment and disposal systems, commonly referred to as a septic systems, consist basically of a septic tank and soil adsorption field or drainfield. It may represent a large fraction of nutrient loads and pathogen impacts in vadose zone and groundwater systems. It includes not only nitrogen (N) and phosphorus (P), but also pathogen indicators such as fecal coliform and Escherich...
متن کاملSimulation of a subsurface vertical flow constructed wetland for CSO treatment.
Constructed wetlands (CWs) have proved to be a highly effective measure to reduce the ecological impact of combined sewer overflows (CSOs) on receiving waters. Due to the stochastic nature of the loading regime and the multitude of environmental influences, assessment of the performance of such plants requires detailed mathematical modelling. A multi-component reactive transport module (CW2D) w...
متن کاملWastewater Treatment with Vertical Flow Constructed Wetland
Water is one of the most important elements involved in the creation and development of healthy life. Haphazard disposal of untreated wastewater from households as well as institutions and industry is causing severe deterioration of water bodies in many urban areas in the developing world. There are several methods to treat the municipal wastewater for intended use. One of the methods of the tr...
متن کاملMetal removal mechanisms in a short hydraulic residence time subsurface flow compost wetland for mine drainage treatment
The performance of an innovative pilot-scale subsurface flow compost wetland for the attenuation of zinc in mine drainage was investigated. The particular novelty of the system, which operated under ambient environmental conditions, was the short hydraulic residence time (HRT) of 7.5 – 14.5 hours. Short HRT is crucial because it reduces absolute wetland size and construction cost, which can be ...
