Le terme « Groupe de services professionnels » (PSG) occupe une place importante dans l'histoire du traitement de l'eau et de l'environnement. Il fait généralement référence à une équipe spécialisée au sein d'une grande entreprise qui fournit une expertise technique, une gestion de projet et des services de conseil liés à la conception, à l'installation, à l'exploitation et à la maintenance des systèmes de traitement des eaux usées et des eaux potables.
Historiquement, l'un des PSG les plus importants faisait partie de USFilter, un acteur majeur de l'industrie du traitement de l'eau. Ce groupe, connu sous le nom de USFilter Operating Services, fournissait des services complets aux clients industriels, municipaux et commerciaux. Ils offraient une large gamme d'expertise, notamment :
La fusion et au-delà :
En 2001, USFilter a été rachetée par Veolia Water, un leader mondial de la gestion de l'eau. Cette acquisition a conduit à une restructuration du PSG au sein de Veolia, de nombreux anciens membres de l'équipe USFilter Operating Services étant passés à de nouveaux postes. Cependant, l'héritage du PSG d'USFilter continue d'influencer l'industrie du traitement de l'eau.

This expanded look at Professional Services Groups (PSGs) in environmental and water treatment builds upon the provided introduction, exploring key aspects in separate chapters.
Chapter 1: Techniques
PSGs employ a diverse range of techniques to deliver their services. These techniques can be broadly categorized as follows:
Process Engineering: This involves applying engineering principles to design, optimize, and troubleshoot water and wastewater treatment processes. Techniques include process simulation using software like Aspen Plus or WERF models, hydraulic modeling (e.g., SWMM), and mass balance calculations. Advanced techniques may include artificial intelligence and machine learning for predictive modeling and optimization.
Instrumentation and Control: PSGs utilize advanced instrumentation and control systems to monitor and manage treatment processes. This includes the installation and maintenance of sensors, actuators, programmable logic controllers (PLCs), and supervisory control and data acquisition (SCADA) systems. Techniques also involve the development of control strategies to optimize plant performance and efficiency.
Data Analytics and Reporting: Modern PSGs leverage data analytics to extract insights from operational data. This includes using statistical process control (SPC) to identify anomalies, developing performance indicators (KPIs), and generating reports for clients. Data visualization tools and dashboards are increasingly used for efficient communication of insights.
Project Management Techniques: Effective project management is crucial for successful PSG engagements. Techniques employed include critical path method (CPM), earned value management (EVM), and agile methodologies. Risk management, stakeholder communication, and change management are also integral aspects.
Chapter 2: Models
Several models underpin the work of PSGs in environmental and water treatment. These range from theoretical frameworks to practical tools:
Water Quality Models: These models predict the fate and transport of pollutants in water bodies. Examples include QUAL2K and MIKE 11, which simulate water quality parameters under various scenarios.
Process Models: These models simulate the performance of specific treatment processes, such as activated sludge or membrane bioreactors. These are used for design optimization, troubleshooting, and predicting the impact of process changes.
Financial Models: PSGs use financial models to assess the economic viability of projects, including life cycle cost analysis (LCCA), return on investment (ROI) calculations, and discounted cash flow (DCF) analysis.
Risk Assessment Models: These help PSGs identify and quantify potential risks associated with projects, allowing for proactive risk mitigation strategies. Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA) are frequently employed.
Chapter 3: Software
PSGs rely on a wide array of software tools to perform their tasks efficiently and effectively:
