ISME/IWA Bio Cluster Award announced 2016 winners
微生物生态学和水/污水处理奖项ISME/IWA Bio Cluster Award公布2016获奖者名单
The ISME (International Society for Microbial Ecology) - IWA (International Water Association) Bio Cluster aims to inspire, facilitate and support the mutual exchange of knowledge in the field of microbial ecology research and its application for water science and management. In order to recognize the importance of interdisciplinary research at the interface of microbial ecology and water/wastewater treatment, the ISME/IWA Bio Cluster Award was created. This prestigious prize rewards interdisciplinary research of unusual merit in this field.
The Grand Prize 2016 will be awarded to both Holger Daims,University of Vienna, Austria, and to Lutgarde Raskin, University of Michigan, USA. They will both act as convenors in the ISME16 program and will give presentations in their respective sessions, Dissimilation of nitrogen compounds, and Microbial ecology meets environmental biotechnology. Mads Albertsen, Aalborg University, Denmark, will receivethe The Rising Star Prize, and will give his presentation in the session Microbial ecology meets environmental biotechnology.

This award will be presented at the coming ISME Congress:16th International Symposium on Microbial Ecology that will take place in Montreal, Canada on 21-26 August 2016. The winner of the award will also be invited to give a talk during the IWA World Water Congress & Exhibition tobe held in Brisbane, 9-13 October 2016.
Wastewater treatment plant transformed into struvite recovery facility inAmersfoort, the Netherlands
荷兰Amersfoort一污水厂转型成为磷回收工厂并将实现污水处理能源自给
The Dutch Waterboard Vallei & Veluwe (The Waterboard) has opened a commercial nutrient recovery facility in partnership with Ostara Nutrient Recovery Technologies and Eliquo Water & Energy. The project is part the Waterboard’s transformation of its Amersfoort Wastewater TreatmentPlant (WWTP) into an Energy and Nutrient Recovery Factory, supported by the EULIFE+ subsidy program.
While seven sewage treatment plants have been converted into “energy and nutrient facilities” in the Netherlands, this is the first facility to produce a “ready to use” fertiliser product, according to Ostara.
Designed to treat more than 8,000 m3/day , the Amersfoort WWTP also acts as a regional sludge-processing hub for a number of WWTPs and imports approximately 40% of sludge from other locations. With approximately 12,000 tonnes of dry sludge being treated annually, the facility was facing high operational costs for energy consumption and processing costs for sludge disposal.
The new facility will produce enough energy to treat all the wastewater from the City of Amersfoort on a 100%energy-autonomous basis, as well as an energy surplus, enough to provide 600 households with green electricity during the year.
Valuable nutrients recovered are sold as a 99.6% pure, granular Crystal Green fertiliser, which is European Certified in the categorywith the highest quality fertilisers. This product is composed of phosphorous, nitrogen and magnesium (5-28-0-10Mg), and is sold and marketed by Ostara through a global network of blenders and distributors to professionals in the turf, horticultural and agriculture sectors. The new facility has the capacity to produce approximately 900 tonnes of Crystal Green annually, and Vallei &Veluwe will receive revenue for every ton of fertiliser it produces.
Launch of EU work on fertiliser criteria for struvite, ash and biochars
欧盟将着手修订现行肥料标准以鼓励营养物质回收和资源产品创新
The European Commission’s JRC (Joint Research Centre) has launched the official process to prepare EU “fertiliser criteria” for struvite, ash-based materials and biochars. The revision of the EU Fertiliser Regulation will facilitate placing on the market of organic and recycled nutrient products whilst ensuringsafety and quality.
The revision of the EU Fertiliser Regulation 2003/2003, currently under discussion, will widen the scope of the Regulation to include inorganic, organo-mineral and organic fertilisers, organic soil improvers, liming products, growing media, plant bio-stimulant and agronomic fertiliser additives. This will considerably facilitate the placing on the market both of organic products containing recycled nutrients (e.g. processed biosolids, digestates, composts, biochars) and inorganic recovered phosphate products (e.g. struvite, phosphatesrecovered from sewage sludge, incineration ash).
Fertilising materials which are certified to comply with the new essential requirements outlined in the EU Fertiliser Regulation (minimum nutrient content, quality and safety criteria) will be authorised to be placed on the Internal Market (transported and sold across the EU), whereas as present such products registered as “fertilisers” in one Member State cannot be exported or require a new registration dossier for sale in another Member State (except in cases where there has been mutually recognised by the authorities of the importing Member State).
Stanford looks to the skies to calculate underground water
斯坦福大学研究人员开放全新卫星图象工具计算地下水流量
A team at Stanford University has pioneered a new use of satellite imagery that could help its home state avoid future water supply issues. Previous Stanford research had already proved satellite images (specifically Interferometric Synthetic Aperture Radar, InSAR) of minute changes in ground elevation could provide reliable clues to underground water flow. The problem was, only tiny sections of the images provide useful data, and analyzing them is a laborious, manual process. A newly developed algorithm not only automates discovery of useful data points, but accurately predicts water flow between them.
The new system isn't specifically designed with California in mind, but with an estimated 30-percent of the state's water coming from such aquifers, and a recent five-year drought, understanding this potentially valuable, but delicate source of H20 is more important than ever.
The new algorithm, developed by Jingyi 'Ann' Chen, a Stanford postdoctoral researcher on the team, allows them to automate the analysis of the InSAR data, which is a huge time saver in itself. Perhaps the more significant part, is that Chen was also able to figure out a way to accurately 'fill in' data in what would otherwise be blind spots. The team tested the algorithm on satellite images of Colorado's San Luis Valley between 2007 and 2011 and the predictions closely matched the real life measurements.
While California's immediate water situation might have taken a step back from the precipice, the Stanford team will continue to incorporate data from other sources to improve and refine the algorithm. The ultimate goal would be to give geologists the tools to be able to accurately estimate the full water 'budget' of anywhere that has the available satellite imagery. Knowing what's flowing underground, and how to get the most yield from it, will have both environmental, and economical benefits, the full implications of which are hard to measure.
