RESEARCH ACTIVITIES OF DEEP LABORATORY >> Observation

• This research activity aims to understand the principles and processes governing the functioning of anthropogenic systems or environments by their observation at the field scale.
• The observation consists in acquiring, at different scales of space and time, series of data which are characteristic of the phenomena studied within systems in real conditions of operation. A large number of data are collected and must be processed, validated and exploited in order to obtain reliable information.
• The development and implementation of adapted instrumentation and protocols (in situ samplers and analyzers, etc.), or protocols for sample collection, are issues that are included in our research in this field.

RESEARCH ACTIVITIES OF DEEP LABORATORY >> Characterization

• Our work in this domain aims to determine :

• The chemical composition of the materials or physical media studied (i.e. their chemical analysis);
• Their physical and possibly mechanical properties;
• Their biogeochemical reactivity under the influence of various factors;
• The properties and characteristics of the flows of matter within and through the media.

• The research focuses on anthropogenic complex materials or environments, such as wastewater and rainwater, solid waste, polluted sediments and soils, biogas, ...

• The knowledge acquired here is necessary for the development of innovative technologies and methods of treatment, their relevant implementation in the different scenarios considered, as well as their environmental and performance evaluation.

RESEARCH ACTIVITIES OF DEEP LABORATORY >> Ecotechnologies

• The laboratory's research in the field of environmental technologies follows 4 complementary orientations :

1. Development of processes for the treatment of water and waste in partnership with socio-economic partners.
   Examples: anaerobic digestion, biomethanation, micropollutants treatment, biogas treatment, pretreatment of organic waste.
2. Design and implementation of monitoring devices dedicated to environmental technologies for water and waste management.
   Examples: DSM Flux, analysis of silicon organic compounds of biogas (siloxanes).
3. Design and implementation from the laboratory scale to the field scale of devices, methods and protocols to assess the performance of environmental technologies and their environmental impacts in normal or impaired conditions of operation.
   Examples: Filters planted with reeds, anaerobic digestion of biowaste, biogas treatment, pretreatment of organic waste.
4. Design, monitoring, management and evaluation of alternative techniques and centralized structures for urban waters management.
   Examples: green roofs, sewer overflow systems, retention and infiltration ponds, etc.

RESEARCH ACTIVITIES OF DEEP LABORATORY >> Methods and tools

• DEEP develops, optimizes and evaluates various approaches, methods and tools dedicated to the treatment, the valorization and more broadly to the management of the discharges resulting from the human activities, the environments or ecosystems which receive them, and systems aiming to optimize the management of flows of matter and energy in a given territory.
  Our research orientations in this domain include :

• description models and tools (software, conceptual models, etc.) ;
• experimental protocols and experimental plans ;
• metrology protocols, acquisition and data collection ;
• data processing methods and tools (software, etc.) including the assessment of uncertainties ;
• sets of performance indicators and decision support criteria ;
• multi-criteria decision support tools ;
• development of sampling protocols.

APPROACHES TO MOBILIZE OUR SKILLS AND EXPERTISE IN OUR RESEARCH ACTIVITIES >> Multi-scale approach

• In our research activities “observation” and “characterization”, working at the laboratory scale allows us to generate knowledge for the fine description of the elementary processes determining the state and dynamics of evolution of the systems under study.
• But to be relevant, our research must also be based on macroscopic and systemic approaches that are conducted at the pilot scale (allowing, for example, integrated multiparameter studies) and field scale (to investigate the spatial and time distribution of the processes and their couplings).
  The contribution of our laboratory, or even its role of coordination of federative structures, platforms and other observatories is a major asset on these aspects.
• The added value of our multi-scale approach is also major in our research activities on “environmental technologies” and “methods” whose principles and proofs of concept can be studied at the laboratory scale, but whose implementation, performance study and validation require pilot and field tests.

APPROACHES TO MOBILIZE OUR SKILLS AND EXPERTISE IN OUR RESEARCH ACTIVITIES >> Pluri, inter, trans- disciplinarity

• It is now well established that environmental sciences and engineering are essentially multidisciplinary. The complex environments, materials and systems that constitute our objects of study cannot be validly apprehended by any single scientific discipline.
• Through the diversity of its staff, our laboratory combines multiple and complementary skills, particularly in chemistry (solutions, interfaces, environmental chemistry and biogeochemistry, etc.), process engineering and urban hydrology. These broad competences allow the emergence of interdisciplinary and transdisciplinary works that open up original perspectives without going too far from our goals thanks to the coherence of our research objectives and our common objects of study.

APPROACHES TO MOBILIZE OUR SKILLS AND EXPERTISE IN OUR RESEARCH ACTIVITIES >> Couplings experimentation / modelling

• Modelling consists not only in using, adapting or developing tools and methods to exploit experimental results, but also in developing simplified representations of our complex objects of investigation that take into account the processes considered to be dominant in their description.
• The complexity of our objects of study (materials and anthropogenic environments, urban and industrial systems, etc.) and our affirmed willingness to direct our research in order to bring elements of answer to questions or expectations from the socio- economic, lead us to build research programs in which multi-scale experimentation and / or observation are at the center of our research. The use of modeling brings us the necessary rationality both in the exploitation of the data thereby generated, but also in the definition and design of our experimental devices and our monitoring protocols.

APPROACHES TO MOBILIZE OUR SKILLS AND EXPERTISE IN OUR RESEARCH ACTIVITIES >> Knowledge-driven, action-oriented Research

• The unifying thread of the research orientations in DEEP lab lies in the fact that our work is guided by environmental engineering objectives and principles. Our reasearch is hence based on actual environmental issues arrising from society or, more specifically, operational actors in relation to urban and industrial environments, as well as questions from researchers.
• This general framework, far from being restrictive, leads us on the contrary to define, program and coordinate our research by mobilizing complementary skills to ultimately lead to the production of knowledge and tools for active intervention on the environment it also creates a dynamic equilibrium between the global study of systems and the understanding of their elementary processes. It is essentially multidisciplinary and aims to generate scientific and technical knowledge allowing a good integration of the socio-economic aspects often determining at the level of the actions to engage.
