Nowadays, most industries are required by law to treat their wastewater, but the selection of the most appropriate wastewater treatment technologies involves a complex decision making process. Environmental decision support systems can be useful to reduce the time needed to make decisions, to improve the consistency and quality of the decisions and to provide direct access to experience, expertise and human-kind reasoning. This study aims to obtain an environmental decision support system to select the most suitable alternative for industrial wastewater treatment in the food, drink and milk sector. The process developed is described, and a set of case studies showing the capabilities of the tool is presented in order to validate the system procedure. © 2016 Elsevier Ltd

This project addresses three main management problems in urban water system: optimal operational control, real-time monitoring and demand forecasting/management. Real-time optimal control deals with operating the main flow and pressure actuators to meet demands using the most sustainable sources and minimizing electricity costs and is tackled using stochastic model predictive control techniques. Real-time monitoring of water quantity and quality refers to the continuous detection and location of leakage and or water quality problems. It uses fault detection and diagnosis techniques. Demand forecasting and management is based on smart metering techniques and includes detailed modelling of consumption patterns as well as a service of communication to consumers. The project will provide an integrated software platform and two real-life pilot demonstrations in Barcelona (Spain) and Lemesos (Cyprus), respectively.

Most of the energy consumed by a water company is used to operate pumping systems. Identifying the optimal schedule for such systems in near real time will drastically reduce energy costs. The pump scheduling problem comprises three main elements: the pumping system, the tank, and the water demand to be satisfied. In this paper, a mathematical programming model and techniques used to solve this problem are presented. This study analyzed a parallel programming paradigm to solve this problem by introducing stochastic programming techniques (scenario tree evaluation) and multisite problems. Numerical experiments were designed and completed on parallel computers combining classical mathematical programming techniques and parallel tools. As a result, the parallel programming strategy was experimentally proven to be a useful technique for near-real-time pump scheduling applications. © 2014 American Society of Civil Engineers.

Ice Pigging is a new pipe cleaning method that uses slush ice to remove biofilm and sediment from the inside of pressurized pipes. It can be used in drinking water networks to effectively remove biofilms and reduce the incidence of discolouration events, and on sewer rising mains to remove accumulated deposits to improve pumping efficiency. The introduction of ice pigging in the pipeline industry represents a major shift in the way that pipes can be cleaned, operated, or prepared for use. The benefits of using ice are numerous. It can be inserted into pipes via existing fittings like fire hydrants, is as effective as swabbing, is very fast - the process is normally measured in minutes and hours - and carries virtually no risk as the ice is harmless. In the unusual event of an issue the ice will eventually melt. Copyright © 2014 ISTT.


The present invention relates to a multiple product belt drier comprising a first air permeable conveyor belt (2) on which the materials to be dried are poured to form a first drying path; at least a second air permeable conveyor belt (3) to assure at least a second drying path for drying the materials (M3) after the first one; air blowing means (10); air heating means (14) for heating the blown air to dry the materials, and a drying air distribution circuit for distributing the drying air towards the materials and the belts; the drying air circuit being provided so that the drying air circulates downwards (D) through the materials to be dried and the belts, and air reheating means (15) are provided between the two paths to reheat the air which has passed through the layer of materials on the first belt (2), before it passes through the layer of materials on the second belt (3).

Aqualogy, specialists in advanced technologies for water management, are to develop a feasibility study into the flow back treatment of water allowing reuse in the shale gas industry. Aqualogy have invested research and development into Electrochemical wastewater treatment and this proven technique comprises three unique patented technologies. These solutions have been tested and are an effective method to treat wastewater in the oil and gas industry. Including two main activities, the study will comprise the setting-up of bench-scale testing of the technology to allow the adaptation of Electrochemical wastewater treatment to the shale gas industry, and also include laboratory tests using real flow back water from an existing exploration project. Aqualogy are committed to sustainable solutions which benefit the environment, the development of this treatment and the project is testament to this ethos as it will provide multiple environmental, social and economic benefits.

BARCELONA -- When you think of drones, you probably think of robot vehicles soaring high over our heads. But there are plenty of hard-to-reach places that aren't out in the open where drones can give you eyes and ears -- and one example is the underground water tanks of Barcelona, Spain, where drones are being sent in to patrol the pipes. The company behind the pilot scheme is Sociedad General de Aguas de Barcelona (SAGB), originally formed back in 1867 to provide water to the Catalonian capital. Under the Aqualogy brand, the company is offering various innovations to water companies around the world, from remote meter reading to apps that tell you the water quality at the beach before you don your bathers -- to drones heading under the streets of Barcelona itself. Barcelona is the largest metropolis on the Mediterranean Sea and doesn't typically get much rain -- but when it rains it pours. That can overwhelm the water removal infrastructure and flood the city, and because Barcelona has a unitary water system -- waste water and rainwater travel through the same pipes -- untreated sewage can end up contaminating the sea. To prevent flooding, the city has, since 1997, built 13 giant underground water retention tanks that hold on to the overflow rather than unleashing pollution into the sea. They prevent 940 tonnes of suspended matter pouring into the Mediterranean each year. Currently, visual inspection and maintenance of these tanks and pipes requires workers to head underground. But in a test project, unmanned aerial vehicles have been taking on the task, steered remotely by an operator watching a feed from the drone's cameras as they pilot it through the pipes. It's a dirty job, but somebody's got to do it -- and with a drone's help, a worker can do it without even stepping into a pair of wellies.
