Wastewater treatment and management in Europe has a large potential for growth; however needs to be supported by education of a new generation of interdisciplinarily trained wastewater professionals able to face future challenges and implement wastewater-related directives in practice. TreatRec, with the participationof two academic partners (ICRA-Catalan Institute for Water Research and University of Girona) and two non-academic (ATKINS and AQUAFIN) identifies several pertinent technological gaps and knowledge needs around which we have built a research programme. TreatRec involves equally academia and industry with a clear aim of producing a group of young researchers capable of conducting high quality research, but also able to address industrial and societal needs and implement wastewater-related directives in practice. The five researchers will conduct their scientific projects in an environment that combines industrial excellence in the development, design, construction and management of wastewater treatment systems, with complementary academic excellence in a) hypothesis-driven research involving the improvement/upgrading of state-of-the art technologies and the deepening the understanding of fate and removal of emerging contaminants in wastewater treatment systems and in b) applied research involving the development of decision support systems which allow for the encapsulation of knowledge for further use in decision-making processes. As a general goal, academic and non-academic partners of TreatRec, including WWTP operators, engineers responsible for the design and a water authority which has experience in water policy implementation, a set of recommendations will be generated to provide guidance for decision-makers on upgrading wastewater treatment plants for future challenges such as microcontaminants removal and nutrient recovery from a sustainable perspective.

Dams and Reservoirs | Year: 2015
The market town of Louth (in Lincolnshire), on the River Lud, has suffered from flooding on many occasions, most recently in 2007. Atkins was commissioned to conduct a feasibility study into the potential for a flood defence scheme. This paper begins once the preferred option of two online flood storage areas had been identified; the brief from this point was to develop their outline design. Atkins worked closely with a contractor to develop a cost estimate for the works and to ensure buildability was considered. The two dams are designed as homogenous earth fill embankments, with heights of circa 6m, and retaining a combined volume of 213 000 m3 (during a flood event); both storage areas fall under the requirements of the Reservoirs Act 1975. As in many cases, these reservoirs present particular challenges; designed to be empty for the majority of their life, they are required to meet the needs of a variety of stakeholders. The design was further complicated by the risk of unexploded ordnance and burrowing animals. This paper presents the outline design under three sections: the location, embankments and control structures. For each section the paper discusses the alternatives considered, the selection process and the adopted design. © 2015, ICE Publishing. All rights reserved.

Vapor cloud explosions (VCEs) cause considerable problems in the chemical and petrochemical industries. They generate damaging levels of overpressure and the possibility of human injury/death, and building/equipment damage. Predicting the possible consequences of VCEs is important to ensure the safe design of existing and new structures. Prediction of the overpressures resulting from a VCE is typically done using simplified (empirical) models, phenomenological models, and computational fluid dynamics models. The focus of this article is on two of the most frequently used simplified prediction methods: TNO multienergy and Baker-Strehlow-Tang models. These models are compared in terms of structural response and vulnerability of damage caused by an explosion. © 2010 American Institute of Chemical Engineers.

The current economic climate in the oil and gas industries has put significant focus on the viability of investments. When oil prices are high, the rate at which the work can be done is often seen as the determining factor for whether a project is successful. However, when oil prices return to lower values, this haste is removed, and the focus returns to the business fundamentals of how you manage your plant, safely making more money. There is a widespread recognition of how front end work is critical to the success of a project. This has been often expressed as "Do the right job, then do the job right". However, with limited funds for investment, and rightful focus of the regulator on not postponing critical spend on safety, the simple premise of "Do the right job" can be deceptively difficult, especially for brownfield modifications and upgrades. This paper outlines some of the challenges in dealing with process safety in early project phases, from ensuring that an appropriate weight is given to process safety in the international context, to approaches and tools for risk assessment in concept selection, dealing with obsolescence, and common pitfalls in processes we have supported over the past 15 years, primarily in the brownfield context. It also presents some of the experience we have seen of good practice in this area, drawn from operations in the UK, EU, Middle East and USA. © 2016 IChemE.

For a weak point source or dipole, or a small body operating as either, we show that the power from a wave energy converter (WEC) is the product of the particle velocity in the waves, and the wave force (suitably defined). There is a thus a strong analogy with a wind or tidal turbine, where the power is the product of the fluid velocity through the turbine, and the force on it. As a first approximation, the cost of a structure is controlled by the force it has to carry, which governs its strength, and the distance it has to be carried, which governs its size. Thus, WECs are at a disadvantage compared with wind and tidal turbines because the fluid velocities are lower, and hence the forces are higher. On the other hand, the distances involved are lower. As with turbines, the implication is also that a WEC must make the most of its force-carrying ability-ideally, to carry its maximum force all the time, the '100% sweating WEC'. It must be able to limit the wave force on it in larger waves, ultimately becoming near-transparent to them in the survival condition-just like a turbine in extreme conditions, which can stop and feather its blades. A turbine of any force rating can achieve its maximum force in low wind speeds, if its diameter is sufficiently large. This is not possible with a simple monopole or dipole WEC, however, because of the 'ηλ/2π' capture width limits. To achieve reasonable 'sweating' in typical wave climates, the force is limited to about 1MN for a monopole device, or 2MN for a dipole. The conclusion is that the future of wave energy is in devices that are not simple monopoles or dipoles, but multi-body devices or other shapes equivalent to arrays. © 2011 The Royal Society.

Many corrosion failures observed in the oil industry are caused by factors unrelated to corrosion engineering, such as inadequate inspections, documentation, communication, and procedures. An evolved corrosion management defnition, along with the introduction of the "integrity management measure," ofers a more practical and comprehensive integrity management approach. Te results are an improved integrity management system and optimization of the associated costs.

This paper recommends that the reliability, obsolescence and integrity management processes related to subsea fields should be integrated into a single process, here termed 'life cycle management', because they all treat in a similar way with the same systems, the overall aim being to maintain system integrity and availability throughout field life. This paper asserts that all three processes should commence early in the design phase of a project and be carried through to decommissioning. It also discusses failure modes, effects and criticality analysis (FMECA) which, it is proposed, should be developed into an integrated system in support of life cycle management, reflecting the root causes of failure as a means of identifying effective and measurable mitigation activities.
