Treatment of polluted river water by a new constructed wetland

by Center for Environment and Energy Research & Studies (CEERS)  (Sep. 1, 2007)

Abstract: A new constructed wetland was built to purify one polluted river in Taiwan, and this study was conducted to evaluate the treatment efficiency of the wetland. Due to the very limitation of available budget, several water quality items, which were stipulated by Taiwan’s Environmental Protection Administration for rivers, in the influent ...

Current pollution status of Yangtze River and controlling measures

by Inderscience Publishers  (May 15, 2008)

The concentration of Persistent Organic Pollutants in Yangtze River in China is increasing steadily, especially in the downstream, where the drainage is often discharged into the water body without any treatment. In this study, the pollution status, trend of mainstream and Three Gorges area are analysed based on the statistical data of the water ...

Study of metal pollution in Sembrong River, Johor, Malaysia

by Inderscience Publishers  (Aug. 25, 2009)

Sampling of the Sembrong River over a 9-month period revealed maximum total aluminium (Al), ferum (Fe) and manganese (Mn) concentrations of 61.0, 33.0 and 1.5 mg/L, respectively, and pH as low as 2.5, making it one of the most metal- and acid-contaminated rivers in Malaysia. The river serves as a fresh water source to water treatment plants ...

River water pollution in Indonesia: an input-output analysis

by Inderscience Publishers  (Jan. 30, 2004)

Data from global environmental monitoring activities have shown alarming environmental conditions in many developing countries. Environmental policies that could improve the environment significantly, while at the same time maintaining the growth of economic activities are needed. Using an input-output analysis, this paper researches such policies ...

Economic analysis of alternative pollution abatement policies: the case of Buriganga River, Bangladesh

by Inderscience Publishers  (Jun. 2, 2014)

The Buriganga River is a prime example of serious surface water pollution problem. So far the emphasis of pollution abatement policy for this river has been solely on the application of command and control (CAC) mechanisms (standards on emission discharges), however little success has been achieved as the polluters seem to be reluctant to comply ...

Aquatic pollution in Mithi River of Mumbai: assessment of physico–chemical parameters

by Inderscience Publishers  (Jan. 17, 2013)

The present investigation along Mithi River of Mumbai deals with the study of physico–chemical parameters like pH, conductivity, solid content, hardness, chloride, sulphate/sulphide, phosphate, biochemical oxygen demand (BOD), chemical oxygen demand (COD), surfactants, oil/ grease and phenol content in river water samples. The study was performed ...

The impact of point sources of pollution on the transport of micropollutants along the river continuum

by IWA Publishing  (Jun. 18, 2014)

The main objectives of the presented study were to quantify the transfer of polychlorinated dibenzo-p-dioxins (PCDDs)/polychlorinated dibenzofurans (PCDFs) (polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans) and dioxin-like polychlorinated biphenyls (dl-PCBs) along the river continuum and to evaluate the impact of wastewater ...

Revealing the relationship between microbial community structure in natural biofilms and the pollution level in urban rivers: a case study in the Qinhuai River basin, Yangtze River Delta

by IWA Publishing  (Jun. 21, 2016)

River pollution is one of the most challenging environmental issues, but the effect of river pollution levels on the biofilm communities has not been well-studied. Spatial and temporal distribution characteristics of environmental parameters and the biofilm communities were investigated in the Qinhuai River basin, Nanjing, China. Water samples ...

Automatic control of pollutant on a shallow river using surface water systems: application to the Ebro River

by IWA Publishing  (Jun. 5, 2014)

In this paper, the problem of automatic control of pollutant on a shallow river using surface water systems is addressed using a benchmark test case based in the Ebro River. The Ebro River presents flooding episodes in the city of Zaragoza in Spring when snow melts in the Pyrenees. To avoid flooding and high pollutant levels in living areas, ...

Diffuse pollution

by IWA Publishing  (Apr. 6, 2012)

Diffuse Pollution or Nonpoint source (NPS) pollution is water pollution affecting a water body from diffuse sources, such as polluted runoff from agricultural areas draining into ...

Water Pollution

by IWA Publishing  (Jul. 25, 2012)

Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In ...

by IWA Publishing  (Feb. 1, 2012)

A team of scientists from eWater CRC based in Canberra and at Griffith University in Queensland has won the WaterSecure - Healthy Waterways Research Award for its work on Prioritisation of Catchment Scale River Restoration within Southeast Queensland (SEQ).   The work is part of a Queensland Government funded ‘proof of ...

Microbiological pollution of surface water in the upper–middle basin of the Reconquista river (Argentina): 2010–2011 monitoring

by Inderscience Publishers  (May 22, 2013)

A microbiological monitoring was conducted on the water at six locations of the Reconquista river, a polluted peri–urban water body of Argentina. Samples were taken from surface water of three tributary streams in the dam outlet and 18 km downstream; samples from the sediments of one of the streams were also taken. For all samples the presence and ...

Remediation of polluted river water by biological contact oxidation process using two types of carriers

by Inderscience Publishers  (Jul. 20, 2009)

Biological contact oxidation technology was used to remediate the polluted river water in Hanyang, China. The purification effect of the polluted river water in three simulated rivers was investigated using two different carriers, i.e., AquaMats made in USA and semi flexible supports made in China. The results showed that when the hydraulic ...
