Since discharge limits are becoming stricter for industrial wastes, textile manufacturers are searching for 3fficient and economical methods of pollution reduction. This is typical of :he situation facing the textile ndustry, especially in the area of :olor pollution emitted into the zarth's waterways. Ozone treatment ;o remove color from wastewater :ould be a solution to the problem of

This study estimates the life cycle water consumption and wastewater generation impacts of a Marcellus shale gas well from its construction to end of life. Direct water consumption at the well site was assessed by analysis of data from approximately 500 individual well completion reports collected in 2010 by the Pennsylvania Department of Conservation and Natural Resources. Indirect water consu...

Wastewaters from leather processing are very complex and lead to water pollution if discharged untreated, especially due to its high organic loading. In this study the survival of different plant species in subsurface horizontal flow constructed wetlands receiving tannery wastewater was investigated. Five pilot units were vegetated with Canna indica, Typha latifolia, Phragmites australis, Steno...

Considering both the volume and the effluent composition, the textile industry wastewater is rated as the most polluting among all industrial sectors. Important pollutants are present in textile effluents; they are mainly recalcitrant organics, colour, toxicants and inhibitory compounds (Khelifi et al., 2008). Textile industries however, have caused serious environmental problems because of the...

introduction water quality trading (wqt) is an economically incentive-based strategy that focuses on finding the optimal discharge permit market for surface water quality management. the amounts of traded discharge permits determine the interactions of emission sources in the market. pollutantsthat are able to provide extra permits can satisfy the demands of other participants for credits. find...

The textile dyeing and printing units in Sanganer town, Jaipur, Rajasthan, India. Discharge a huge volume of mostly untreated textile dye wastewater (10,000-15,000kl/day) into various pools and drain adjoining the textile printing units. A number of azo dyes are used in textile printing industries, As a result. The textile waste waters are loaded with them, along with other chemicals used durin...

OBJECTIVE Anti-infectives are constantly discharged at trace levels in natural waters near urban centers and agricultural areas. They represent a cause for concern because of their potential contribution to the spread of anti-infective resistance in bacteria and other effects on aquatic biota. We compiled data on the occurrence of anti-infectives published in the last 24 years in environmental ...

Perfluorinated substances are listed among emerging contaminants because they are globally distributed, environmentally persistent, bioaccumulative and potentially harmful. In a three-year monitoring campaign (2010-2013) we investigated the occurrence, sources and fate of nine perfluoroalkylcarboxylic acids and three perfluoroalkylsulfonic acids, in the most industrialized region of Italy. Comp...

Phosphorus is an essential nutrient for all living organisms. However, high concentrations in a water body accelerates eutrophication. Discharge limits for phosphorus are getting tighter for wastewater treatment plants, thus new tertiary treatments for removal have to be considered. In addition, hygienization of wastewater may become mandatory. At Viikinmäki wastewater treatment plant, the phos...
