Monitoring intracellular polyphosphate accumulation in enhanced biological phosphorus removal systems by quantitative image analysis
A rapid methodology for intracellular storage polyphosphate (poly-P) identification and monitoring in enhanced biological phosphorus removal (EBPR) systems is proposed based on quantitative image analysis (QIA). In EBPR systems, 4′,6-diamidino-2-phenylindole (DAPI) is usually combined with fluorescence in situ hybridization to evaluate the microbial community. The proposed monitoring ...

Integrated process control for recirculating cooling water treatment in the coal chemical industry
This work focused on the integrated process of the recirculating cooling water (RCW) treatment to achieve approximate zero emission in the coal chemical industry. The benefits of fractional and comprehensive RCW treatment were quantified and qualified by using a water and mass balance approach. Limits of cycle of concentrations and some encountered bottlenecks were used to ascertain set target ...

Dairy Effluent Treatment - Total Phosphorus Monitoring
Dairy Crest's Davidstow site operates a sophisticated effluent treatment plant to ensure that the local aquatic environment is protected. The treatment plant has been upgraded to keep pace with the expansion of the factory and a number of our monitoring instruments have been employed to make the operation of the plant as efficient as possible. During 2011, the Environment Agency approached Dairy ...

River conservation is ‘blind’ without high-resolution monitoring
Scientists from the University of Portsmouth have been investigating nutrient concentrations in the Upper River Itchen, in Hampshire, UK, on behalf of Salmon & Trout Conservation (S&TC) to better understand where phosphorus is coming from and how it is impacting river ecology. The work has been ongoing for over three years and Lauren Mattingley, Science Officer for S&TC says: ...

A multi-parameter analyzer helps a Kentucky treatment plant step up to the plate and meet a new phosphorus limit in its permit
In 2001, the Lexington Fayette Urban County Government West Hickman Creek Wastewater Treatment Plant in Nicholasville, Ky., was starting Phase II of its third upgrade since 1972, when the state imposed a phosphorus limit. Total phosphorus hovered around 6 mg/l, but the permit required 1 mg/l monthly average and 2 mg/l daily maximum from May through October. Engineers from Tetra-Tech, the ...

Bioremediation of soil
In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

Evaluating slurry broadcasting and injection to ley for Phosphorus losses and fecal microorganisms in surface runoff
The recent growth in the size of dairy cattle farms and the concentration of farms into smaller areas in Finland may increase local water pollution due to increased manure production and slurry application to grass. Therefore, a field study was conducted to monitor losses of total phosphorus (TP), dissolved reactive phosphorus (DRP), and fecal microorganisms in surface runoff from a perennial ...

WWTP installs new affordable ortho-phosphorus analyzer to help contain escalating chemical costs - Case Study
Wisconsin’s Department of Natural Resources recommended a reduction in the state’s phosphorus limit from 1 ppm to 0.05 ppm for inland lakes and streams (0.5 ppm for the Great Lakes) in efforts to improve water quality and reverse eutrophication of state’s lakes and rivers. These new limits when adopted will force many WWTPs to spend more on chemicals and invest in new equipment. ...

Curren hits the bull`s eye using online process analyzers - Case Study
The Howard F. Curren Advanced Wastewater Treatment Plant is one of the largest nitrification/denitrification filter plants in the world with a design capacity of 96 million gallons per day average daily flow. It serves about 110,000 accounts in the City of Tampa and portions of Hillsborough County, Fla. Over the years, the quality of its treated effluent has been frequently cited as the primary ...

Managing phosphorus levels to prevent algae blooms
When phosphorus levels in a water body reach abnormally high amounts, it can severely disrupt natural cycles and trigger a chain reaction of ecological imbalances. Rapidly multiplying organisms such as algae can benefit the most from this excess of nutrients. If not dealt with promptly, these algae can form large, unsightly, and potentially toxic algal blooms, known as harmful algal blooms ...

Pilot-scale study of vertical flow constructed wetland combined with trickling filter and ferric chloride coagulation: influence of irregular operational conditions
The aim of this study was to characterize the efficiency of an intensified process of vertical flow constructed wetland having the following particularities: (i) biological pretreatment by trickling filter, (ii) FeCl3 injection for dissolved phosphorus removal and (iii) succession of different levels of redox conditions along the process line. A pilot-scale set-up designed to simulate a ...

Comparison of simple, small, full-scale sewage treatment systems in Brazil: UASB–maturation ponds–coarse filter; UASB–horizontal subsurface-flow wetland; vertical-flow wetland (first stage of French system)
This paper presents a comparison between three simple sewage treatment lines involving natural processes: (a) upflow anaerobic sludge blanket (UASB) reactor–three maturation ponds in series–coarse rock filter; (b) UASB reactor–horizontal subsurface-flow constructed wetland; and (c) vertical-flow constructed wetlands treating raw sewage (first stage of the French system). ...

The US EPA Lake Erie indicators monitoring program 1983 - 2002:trends in phosphorus, silica and chlorophyll a in the central basin.
During the past 20 years, Lake Erie has exhibited a series of complex chemical changes resulting from changing anthropogenic influences and introductions of exotic species. Since 1990, some apparent trends in nutrient concentrations have been inconsistent with the predictions of models originally used to guide Lake Erie water quality management. We performed time trend analysis on total ...

High frequency monitoring needed to protect UK rivers - Case Study
The science behind nutrient pollution in rivers is still poorly understood despite the fact that nitrate and phosphate concentrations in the UK’s rivers are mostly unacceptable, although an element of uncertainty exists about what an acceptable level actually is. Key to improving our understanding of the sources and impacts of nutrient pollution is high-resolution monitoring across a broad ...
