Sewage pollution in New York, USA: impact of the ‘Right to Know’ Act
In 2012, New York, USA enacted the Sewage Pollution Right to Know (SPRtK) Act, which requires public notification of untreated and partially treated sewage discharges. With the passing of this law, New York joined 12 other states that have similar laws but none as comprehensive as New York's. As part of the SPRtK Act requirements, aggregated sewage discharge reports (SDRs) are made available ...

GK-PSH Type Water Spray Dedusting Lime Slaker
GK-PSH Type Water Spray Dedusting Lime Slaker Model: A type \C type\E type based on different lime slaker capacity GK-PSH Type Water Spray Dedusting Lime Slaker Features: It adopts natural water cycle to spray water mist to absorb the dust entrained in the hot vapor. The dust absorption rate is 100%. The warm lime water from the precipitator is used to slake the CaO. No sewage discharge. ...

Recent papers on marine outfalls
In a dispersive coastal area under multiple organic enrichment sources, stable isotopes were used to trace organic sources of carbon and nitrogen in sediments and benthic macrofauna. The Bivalve Abra alba and the Polychaetes Nephtys sp. and Pectinaria (Lagis) koreni were reliable indicators of the input of terrestrial-derived organic matter into this coastal area, either originated in outfall ...

Effluent
Effluent is an outflowing of water or gas from a natural body of water, or from a human-made structure. Effluent is defined by the United States Environmental Protection Agency as “wastewater - treated or untreated - that flows out of a treatment plant, sewer, or industrial outfall. Generally refers to wastes discharged into surface waters”.[1] The Compact Oxford ...

Distribution and accumulation of heavy metals in surface sediments from a subtropical bay affected by the Special Economic Zone, China
The concentrations of nine metals (Cd, Cr, Cu, Ni, Mn, Pb, Zn, Fe, and Al) in surface sediments from 14 sampling sites in Shantou Bay were determined in order to understand current metal levels and spatial distribution due to the rapid development of the Shantou Special Economic Zone. Results showed that metal concentrations in surface sediments varied from 0.31 to 1.74 mg kg–1 for Cd, ...

Unlimited Fines for Illegal Sewage Discharges?
The government has announced that it is keen to lift the £250,000 cap for penalties relating to illegal sewage discharges into rivers and the sea carried out by water companies, part of plans to “make polluters pay” that will include all sources of pollution, everything from sewage to plastics and chemicals. Water suppliers are permitted to discharge untreated sewage into ...

Evaluating spatial-temporal variations and correlation between fecal indicator bacteria (FIB) in marine bathing beaches
The horizontal distribution and temporal variation of bacterial indicators (total coliforms (TC), fecal coliforms (FC), enterococcus (EC) and Escherichia coli (E. coli)) were investigated to identify the proper bacterial indicators for a marine bathing beach in China. Two different sampling efforts were conducted during dry weather and two large rain events at Xinghai Bathing Beach in Dalian, ...

Horizon and water treatment
Horizon is an environment company focused on water treatment.In the latest years,with the improvement of industrial economy,water quality is becoming worse and worse.To prevent the pollution trend,our government has raised the standard of sewage discharge several times,so traditional process and technology of water treatment can’t apply for the environmental requirements and technology ...

Selection of Anti Weld Spatter Coating
As the phenomenon of welding spatter is very common, the use of anti-spatter coating for welding is also very extensive. For general structural parts, the type of welding anti weld spatter coating has little effect, as long as it can effectively prevent welding spatter from adhering to the working surface in the welding process. However, for some key products and workpieces, such as high pressure ...

Operational decision support system for large combined sewage systems: Lisbon/Tagus estuary case study
Managing combined sewage systems in large cities discharging to coastal waters, often bearing recreational activities, remains a challenge. Studying the impacts of such discharges requires the development of specific models. Hydrodynamic and water quality modelling of coastal waters employs numerical methods and algorithms, leading to the design of complex models which require expert use. The ...

No Public Funds For Water Firms ‘Unless Sewage Spills Stop’
A Liberal Democrat-requested amendment to the UK infrastructure bank bill has just been accepted by the government, which means that public taxpayer funds may not be invested in water companies if they don’t put appropriate measures in place to prevent sewage discharges from taking place. The UK Infrastructure Bank has been designed to help the government achieve its net zero carbon ...

Cape Town: Sanitation Status
Sanitation provision in Cape Town (South Africa’s second-largest city) is good by comparison with most cities in sub-Saharan Africa, in line with South Africa’s relatively high per-capita GNP: most people have access to a hygienic toilet, and most sewage is treated before discharge to the environment in a controlled ...

Treatment of the city of Oudenaarde (Belgium) sewage discharge canal case study
Executive Summaryc A canal responsible for carrying sewage away from the City of Oudenaarde to the Scheldt River was partially dammed in 1965 leaving an area of open water of approximately 1 hectare (600 meters by 17 meters). As the canal was only partially dammed, water from the canal continued to flow into the Scheldt River. Two large municipal sewage collection discharge pipes feed the canal. ...

An alternative to biological treatment for sewage
Most sea-side towns discharge sewage into the sea, normally some distance off-shore, via an extended out-fall sewer. A town of 100,000 population will produce more than 14,000 cubic metres (3,000,000 gallons) of sewage every day of the year. No small problem. In some coastal locations the sewage used to receive only basic, simple treatment, usually "screening" to remove any large objects, ...

Durban Ethekwini: Sanitation status
Sanitation provision in eThekwini (South Africa’s third-largest city) is reasonably good by comparison with most cities in sub-Saharan Africa, in line with South Africa’s relatively high per-capita GNP: most people have access to a hygienic toilet, and most sewage is treated before discharge to the environment in a controlled manner. However, a significant minority of the city’s ...

Wastewater from metal finishing industry set for more regulation from the Environmental Protection Agency
The U.S. Environmental Protection Agency (EPA) recently released its preliminary 2014 Effluent (liquid waste or sewage discharged into a river or sea) Guidelines Program, which outlined more regulations for wastewater from those within the metal finishing industry. A filter press has been a long-trusted solution for treating metal waste, even for those applications that are difficult to ...

Restoration of two shallow, urban lakes using the phosphorus inactivation method – preliminary results
This paper presents the initial environmental effects of polyaluminum chloride application on the water quality of two connected, shallow urban lakes in the Mazurian Lakeland, Poland. The water quality of Lake Domowe Duże (62 ha, mean depth 2.4 m) and Lake Domowe Małe (11 ha, mean depth 2.8 m) in Szczytno did not improve after sewage discharge cutoff. Thus, local authorities ...
