The extracellular polymeric substances and microbial cytoplasmic contents seem to hold inorganic ions and organic products, such as proteins and carbohydrates that are of critical importance for the metabolism of hydrolytic and acidogenic anaerobic microorganisms. The addition of soluble microbially recovered nutrients from thermally treated digestate sludge, for the fermentation of thermally hydrolysed waste activated sludge, resulted in higher volatile fatty acids yields (VFAs). The yield of VFAs obtained from the recovered microbial nutrients was 27% higher than the no micronutrients control, and comparable to the yield obtained using a micronutrients commercial recipe. In addition, the use of a low pH resulting from a high sucrose dose to select spore forming acidogenic bacteria was effective for VFA production, and yielded 20% higher VFAs than without the pH shock and this associated with the addition of recovered microbial nutrients would overcome the need to thermally pre-treat the inoculum. © 2016 Elsevier Ltd.

Maintaining the Safety of Our Dams and Reservoirs - Proceedings of the 18th Biennial Conference of the British Dam Society | Year: 2014

Lack of adequate freeboard and concerns over ability of a masonry spillway to pass the design flood were resolved by providing a labyrinth weir and replacing the masonry spillway. The existing spillway was evaluated using computational fluid dynamics and the design was tested by physical modelling. The design rehabilitated the reservoir by providing improved freeboard and durability to withstand the design flood.

Proceedings of the Institution of Civil Engineers: Civil Engineering | Year: 2016

In Llanelli, South Wales, high volumes of surface water have led to excess discharges from combined sewer overflows into designated shellfish waters and the risk of widespread property flooding. A comprehensive catchment-wide modelling assessment was undertaken to develop a pioneering, community-focused strategy based on retrofitting sustainable drainage systems. This paper outlines the approach taken to develop and compare catchment strategy options; describes the journey through delivery and performance evaluation; and explores the social, environmental and economic constraints and opportunities. The project is a blueprint for integrated catchment management and water-sensitive urban design, promoting best practice in flooding mitigation and climate-change resilience across the UK. © 2016, ICE Publishing.

The potential effects of abstraction for water supply on salmonid populations in England and Wales are reviewed. The duties of water resource planning and the contribution of the water industry investment in river basin management planning are discussed. Given the possible effects of climate change on public water supply and demand, and the uncertainty of hydroecological relationships, key principles to ensure long-term investment by water utility companies to meet European Union Water Framework Directive standards achieve the best benefit for salmonids are recommended. © 2011 Blackwell Publishing Ltd.

Gough R, Holliman PJ, Willis N, Jones TG, Freeman C. 2012. Influence of habitat on the quantity and composition of leachable carbon in the O2 horizon: Potential implications for potable water treatment. Lake Reserv Manage. 28:282-292. Organic material leached from the organic (O) horizon of soils is a major source of natural organic matter (NOM) in surface waters. Dissolved organic carbon (DOC) is a known precursor for the formation of disinfection by-products (DBPs), including trihalomethanes (THMs), formed during chlorination. In this study the concentration and composition of leachable O2 horizon DOC from 5 habitats within a United Kingdom upland reservoir catchment (beech, spruce, larch, and pine forests and blanket peat) were compared with an emphasis on potential treatment implications using XAD fractionation and THM formation potential (THMFP) tests. Statistically significant differences were found between habitats, with pine and larch leachates yielding particularly high DOC concentrations (mean 19.3 and 13.4 mg/L, respectively) and THMFP 7d values (mean 1306 and 1527 μg/L, respectively). The interspecies variation observed suggests that the typical distinction made between deciduous and coniferous species in previous studies is overly simplistic. Interestingly, peat leachate exhibited a surprisingly low DOC concentration (mean 9.0 mg/L), suggesting that the high DOC flux associated with these habitats may be the result of other factors such as depth of organicmatter and mineral content. Averaged across all habitats, mean standardized THMFP (STHMFP) was highest in the hydrophobic acid (HPOA) fraction, although substantial differences in the relative reactivities of fractions were found between habitats. Synergistic effects are also likely to complicate the relationship between fractional character and STHMFP. © Copyright by the North American Lake Management Society 2012.

Global and Planetary Change | Year: 2010

Many Mediterranean steepland rivers are flanked by extensive alluvial and colluvial deposits, but Late Quaternary histories of channel and hillslope behaviour remain poorly constrained, primarily because of the limited availability of material suitable for dating. Study of a 4.8 km long reach of the Anapodaris Gorge, located in the lower part of an ∼ 500 km 2 catchment in south central Crete, reveals a succession of well preserved, coarse-grained (predominantly cobble to boulder) and fine-grained (predominantly silt to sand) alluvial deposits that locally interfinger with, or are overlain by, coarse colluvial and tributary stream deposits. Detailed ground surveys, geomorphological mapping, sedimentological investigations, and geochronology (optically stimulated luminescence, radiocarbon, and lichenometry) have allowed detailed reconstruction of the timing and pattern of sedimentation and erosion over the mid to late Holocene. Widespread, coarse-grained aggradational episodes at c. 4.86-4.20 and c. 3.40-3.00 ka have been punctuated by incisional episodes and coarse sediment export, resulting in a suite of alluvial terraces. Comparison with other proxy Mediterranean environmental change records, particularly high-resolution marine and lake records, suggests that these aggradational/incisional episodes were primarily climatically driven, reflecting changes in the balance between hillslope/tributary sediment supply and high-energy flood events. By contrast, phases of widespread fine-grained aggradation at c. 1.90 ka, 1.13 to 1.10 ka, 0.85 to 0.70 ka and 0.21 ka provide evidence for decreases in flood competence, possibly coupled with up-catchment historical land use changes. Since the middle of the nineteenth century, several large floods have formed localised boulder berms and splays and have contributed to stripping of the fine-grained deposits from many parts of the gorge. The findings from the Anapodaris Gorge demonstrate the sensitivity of Mediterranean steepland catchments to rapid and/or short-lived Holocene climate change but also highlight the need for higher resolution data on historical and prehistoric land use changes. © 2009 Elsevier B.V.

Dams and Reservoirs | Year: 2015

On average, there are three to four major dam incidents or accidents in the UK every year. It was reported in ‘New Civil Engineer’ (NCE) by reservoir engineers ‘that as many as four dams and reservoirs could be at risk from bursting every year’ (Anon, 2002). The Civil Contingencies Act 2004 provides a framework for organisations and authorities who plan for emergencies. It explains how these agencies should work together and identifies which organisations are responsible for responding to emergencies. However, it may be surprising to know that reservoir incidents and the potential consequences are rarely clearly understood among these agencies. How prepared are we for a major reservoir emergency? This paper will provide an overview of the emergency planning guidance relating to dams and reservoirs. It will discuss the requirement for ‘on-site’ and ‘off-site’ emergency plans and explains how Dwr Cymru Welsh Water are building and testing their own plans and the lessons learnt. General emergency planning legislation will be discussed. It will conclude with the ways in which engineers, undertakers, emergency planners and response organisations can work together effectively to develop emergency plans. © 2015, ICE Publishing.

Dams and Reservoirs | Year: 2015

Several measures in the interests of safety (MITIOS) were required on Ystradfellte dam and draw-off tower. This paper describes the challenges and solutions to allow the replacement of landings and ladders within the tower. Although the measures should have been relatively straightforward, complex works were required to maintain a robust treatment works supply whilst taking the single-source supply main out of service. Live cross-connections were carried out using ‘UTS flow stops’ and safe isolations were achieved using remote-operated vehicles and diving teams. Access to key areas posed a challenge due to a life-expired access bridge and infrastructure with severe corrosion. The proposed structural solution for the tower refurbishment utilised ‘Tekla’ three-dimensional modelling. Concerns with respect to high flows through aged pipework were also addressed with pipe joint refurbishment and the installation of a cone regulator valve. The tower works were completed in June 2015, ahead of the major spillway upgrading works. © 2015, ICE Publishing. All Rights Reserved.
