Abstract Textile wastewater discharged into rivers often triggers a decrease in water quality and causes harm to its aquatic ecosystem. wastewater, which may contain nutrients, organic compounds, heavy metals, can be managed using constructed wetland system. Vetiver grass is known for ability treating polluted waters, though the information related potential controlling textile pollution ripari...
Abstract Background High-strength wastewater defined by elevated levels of hazardous pollutants measured in BOD, heavy metals, nutrients and other toxic substances. This kind discharged to water body without treatment from different industrial sectors that adversely affects aquatic environment downstream consumers. The general objective this study is investigate efficient substrate with selecte...
A combined constructed wetland formed by a facultative pond (FP), a surface flow wetland (SF) and a subsurface flow wetland (SSF) was studied from December 2004 until September 2005 in north-western Spain in order to evaluate their efficiency in the removal of pathogenic and indicator microorganisms and to determine their relationships. Microbial removal ranged from 78% for coliphages to over 9...
Support material used in constructed wetlands has been shown to be a key element and significant mechanism in the process of contaminants removal from sewage including phosphorus compounds. Recycled waste tires processed into small chips that are similar to conventional stone aggregate are currently used in the construction of septic system leach fields and could be a green alternative as suppo...
