AquaFit4Use-Session within the IWA-Water & Industry Conference
We are very happy to officially present you the program of our AquaFit4Use-Session within the IWA-Water & Industry Conference that will take place from 1st to 4th May 2011 in Valladolid (Spain).
In a global scenario of increasing energy prices and quest for sustainable human activities, the industrial waste treatment of the XXI century must undergo a severe revision of its current practices. These must aim at developing a new generation of energy-efficient and resource recovery processes, while complying with the ever stricter environmental regulations. This event of the IWA Chemical Industries Specialist Group will address issues related to wastewater, gas and solid waste management in industry with a special focus on energy efficiency and sustainability.
This conference is an opportunity to meet with professionals from academia, industry and public administrations. The event aims at providing a forum for environmental and chemical engineers, microbiologists, chemists and policy makers to present their most recent technological and scientific breakthroughs in the fields of management, characterization, minimization and abatement of industrial wastes. Topics covered will include:
· Environmental policy and management (LCA, sustainability analysis, regulations, permit etc)
· Microbiology of toxic pollutant biodegradation.
· Industrial VOCs and Odour Treatment.
· Characterization (toxicity assessment, ecosystem and public health assessment, endocrine disruption, emerging pollutants, analysis etc).
· Energy and resource recovery, cleaner production, pollution prevention.
· Physical and chemical treatment methods.
· Biological treatment methods (aerobic, anaerobic, suspended growth, attached growth etc).
· Advanced and emerging technologies (advanced oxidation and reduction, nano-materials, membrane filtration, fuel-cells etc).
· Recipients and down stream effects (fate & modeling of emerging and recalcitrant pollutants during treatment, etc).
· Solid Waste Management (sludge minimization technology, industrial solid waste treatment etc).
· Industrial Ecology.
· Case studies.
Therefore, within Aquafit4use we cannot miss this opportunity of presenting our current results but also to open a debate for the exchange of information on the identified bottlenecks and limits of the concepts, scenarios and technologies based on the lab results and pilot experiences, to define alternative solutions and to open new perspectives for the research period, if necessary. For that reason we have organized an Aquafit4use-Session in which the following presentations will be given:
AquaFit4Use: Sustainable Industrial Water Use in Practice
W.G.J.M van Tongeren, TNO, will present the focus of AquaFit4Use project and the strategy we have to achieve our aim of optimal Water Quality Management, giving clear answers to questions like:
What is the water quality really needed?
- How can water of this quality be produced?
- How can this water quality be monitored and controlled?
Application of the WQMT to CHS case study
Mónica de Gracia, Begoña Goyenechea, Filip H.A. Claeys, Izaro Lizarralde
First real case studies using the novel software framework WQMT for the representation, simulation and optimization of industrial water networks will be presented. The study has two main goals: supporting the development of the tool through its use and finding new opportunities for reducing water consumption in the water network. This presentation mainly focuses on the application of the WQMT to study Gutarra (CHS, food industry) water network. Current WQMT scope and limitations to carry out this task will be shown.
Membrane bioreactor technology compatibility with chemical wastewater
H. De Wever, C. Huyskens, G. H. Kristensen, U. Wegmann, S. Meul, P. Cassiers, P.J. van Staveren and G. Lengden
This presentation focussed in answering how well MBR technology can cope with the high variability and specific product streams appearing in the final effluent of chemical plants. Results from MBR pilot trials performed at two sites will be presented.
Industrial waste water re-use: Application of 3FM® (New high speed filtration system) as pre-treatment
S. Mauchauffee*, M.-P. Denieul, B. Desvarreux-Larpenteur and M. Coste
The main results obtained during the testing of the new 3FM® filter (Flexible Fiber Filter Module) as tertiary treatment of pulp and paper waste waters to protect membrane treatment after a biological process will be presented.
Reducing water footprint of cooling towers with CapDI
T. Poots and Erik Driessen , Voltea
The principle of CapDI to remove salt will be presented as well as its application in re-circulating cooling systems where it offers water and chemical savings and boosts the performance of the cooling system. Up to 40% water savings and 80% chemical savings, are achievable.
Finding economically the most efficient operating parameters of UV/H2O2 process: a case study – decolorization of C.I. Reactive Blue 268 solution
N. Novak, A. Majcen and Le Marechal
The optimization procedure for optimizing the UV/H2O2 process for remediation of colored wastewaters considering operating and economic efficiency simultaneously will be presented. The presented approach is based on a response surface methodology in conjunction with mathematical programming.
Chemical Precipitation Applied to Reduce Silica Content in Paper Mill Effluents
D. Hermosilla, R. Ordóñez, L. Blanco, A. Blanco
High content of silica causes a lot of scaling problems in reverse osmosis (RO) systems. This presentation is based on the study of the coagulation process applied to reduce the presence of silica in a paper mill effluent. The effect of different coagulants at different water pH conditions will be shown and discussed.
Softening and removal of scaling compounds for industrial wastewater re-use
E. Barbier, S. Mauchauffee, MP Denieul1, M. Coste and M. Engelhart
Most precipitation processes are positively impacted (size of particles, reduced post precipitation, increase precipitation kinetics, etc.) by increasing solid content (sludge recirculation). Homogeneous solid suspension is then critical criteria to design the process. Veolia will present an advanced precipitation process with sludge recirculation including forced-circulation, draft-tube crystallizers with custom mixers that yield very high circulation to minimize supersaturated zones and the specific design of the Turbomix reactor to improve solid particle homogenisation.
New Mathematical Model Library for Industrial Water Network Optimization
I. Lizarralde, F.Claeys, R. Ordóñez, M. de Gracia, L. Sancho and P. Grau
A new library of mathematical models able to reproduce a set of traditional and innovative wastewater treatment technologies in industry will be presented. These models implemented in the WQMT allow the simulation and finding optimum solutions of industrial water circuits in paper and food sectors. Finally, a case study based on a paper mill will be presented to show the ability of the models to reproduce real water networks and the capability of the tool to obtain optimum solutions.
Water quality monitoring: Evaluation of sensors
Y. Ladegaillerie, J. Chabrol, M. Chardin, C. Lemoine, M. Maurel and A. Monsorez
Veolia will present the application of a test protocol of instrumentation for industrial water and wastewater applications. The aim is to have a common language to get comparable and reliable data about sensor performances. Pre-required information is needed to make the protocol fit with the targeted application, including the place and the function of the instrument in the process.
Furthermore we will use this opportunity to organize an AquaFit4Use-Workshop that will be hold during the conference with a theoretical and practical perspective. The workshop will focus on the Water Quality Management Tool. Do not miss this opportunity to learn from each other.
On the other hand, the AquaFit4Use Workshop that had planned in collaboration with University of Maribor on textile dyes cannot be organized this time due to the dense program of the conference.
Valladolid is about two hours drive from Madrid. Anyway, I recommend to take the high-speed train (AVE or ALVIA) which takes approximately 50 minutes. Check the website of the Spanish national railway company RENFE for timetables and bookings (http://www.renfe.es/horarios/english/index.html ).
