Up-to-date information about the Earth’s surface provided by land cover maps is essential for numerous environmental and management applications. There is, therefore, a clear need continuous reliable monitoring of changes. The growing availability high resolution, regularly collected remote sensing data can support increasing number applications that require spatial resolution products are frequently updated (e.g., annually). However, large-scale operational mapping requires highly-automated...
Sidestream EBPR (S2EBPR) is an emerging alternative process to address common challenges in related weak wastewater influent and may improve stability. A systematic evaluation comparison of the performance microbial community structure was conducted between conventional S2EBPR facilities North America. The statistical analysis suggested higher stability than EBPR, although possible bias associated with other plant-specific factors might have affected comparison. Variations stoichiometric...
The first full-scale nutrient recovery installation in North America became operational May 2009 at the Clean Water Service's Durham Advanced Wastewater Treatment Plant Tigard, Oregon. Recovering ammonia and phosphorus from dewatering side stream as struvite has a positive impact on plant operations. Significantly reducing recycle lowers loading plant, stabilizes biological removal, reduces amount of chemicals needed to remove phosphorus, both dry tonnes biosolids generated content...
Abstract This paper summarizes recent developments in biological phosphorus removal modelling, with special attention to side-stream enhanced (S2EBPR) systems on which previous models proved be ineffective without case-by-case parameter adjustments. Through the research and experience of experts practitioners, a new bio-kinetic model was developed including an additional group biomass (glycogen accumulating organisms – GAOs) processes (such as aerobic anoxic maintenance for PAO GAO;...
ABSTRACT New radiocarbon ( 14 C) dates suggest a simultaneous appearance of two technologically and geographically distinct axe production practices in Neolithic Britain; igneous open-air quarries Great Langdale, Cumbria, from flint mines southern England at ~4000–3700 cal BC. In light the recent evidence that farming was introduced this time by large-scale immigration northwest Europe, expansion within Britain extremely rapid, we argue synchronicity supports speed colonization reflects...
Abstract Neolithic stone axeheads from Britain provide an unusually rich, well-provenanced set of evidence with which to consider patterns prehistoric production and exchange. It is no surprise then that these objects have often been subject spatial analysis in terms the relationship between particular source areas distribution made those stones. At stake such are important interpretative issues do how we view role material value, supply, exchange, demand societies. This paper returns some...
Deep-bed denitrification filters have been successfully used for over 25 years to meet total nitrogen (TN) limits of 3 mg/L and even lower. In some cases, the wastewater treatment plants (WWTPs) also had moderate phosphorus (TP) limits, in range 0.5 2 mg/L. More recently, WWTPs are required very low TN TP simultaneously. For example, as result development maximum daily loads (TMDL) Chesapeake Bay, many Maryland Virginia will be 0.3 on a 12-month average basis. A number these more stringent...
In this study, a full-scale pilot testing was performed with side-by-side operation of conventional enhanced biological phosphorus removal (EBPR) process and side-stream EBPR (S2EBPR) process. A comparison the performance, activities population dynamics key functionally relevant populations between two configurations were carried out. The results demonstrated that, same influent wastewater characteristics, S2EBPR configuration showed more effective stable orthophosphate (PO4-P) performance...
The authors of this article consider the relationship in European prehistory between procurement high-quality stones (for axeheads, daggers, and other tools) on one hand, early mining, crafting, deposition copper other. data consist radiocarbon dates for exploitation stone quarries, flint mines, information regarding frequency through time jade axeheads artefacts. By adopting a broad perspective, spanning much central-western Europe from 5500 to 2000 bc , they identify general pattern which...
Pilot testing of upflow continuous backwash filter (UCB) for tertiary denitrification and phosphorus removal was conducted at the Hagerstown wastewater treatment plant. The pilot to determine performance capabilities filters under cold weather operation low effluent total nitrogen (TN) limits. As part a state-wide strategy meeting nutrient reduction goals Chesapeake 2000 Agreement with U.S. Environmental Protection Agency other Bay watershed states, State Maryland is requiring all WWTPs >...
Abstract Flatfish are ecologically diverse species that commonly occur in marine environments, but also estuarine and riverine habitats. This complicates the examination of potential role flatfish ‘marine fish event horizon’, an economic shift human exploitation from freshwater to during 10–11th centuries CE around southern North Sea. study represents first multi‐disciplinary investigation remains make species‐specific interpretations exploitation.
