STOAT WwTW Modelling Software Training

Course overview

This course provides delegates with an in-depth understanding of the capability and features of WRc’s free STOAT software, allowing them to get the best out of the tool for use in wastewater treatment process design. 

The software used is a globally-used PC-based computer modelling tool designed to dynamically simulate the performance of wastewater treatment works, enabling the user to optimise the response of the works to changes in the influent loads, works capability or process operating conditions. More information about STOAT can be found here.

As part of the course, users are encouraged to bring an example problem, for which the trainer will show how STOAT can be applied to their areas of concern, providing a tailored and unique learning experience. Upon completion of this training, delegates will have a comprehensive understanding the use and limitations of computer modelling for wastewater process design and assessment, specifically through the use of a widely-used tool.

Who can benefit?

Delegates may include senior technicians, works managers, process scientists and engineers working to design wastewater treatment plant processes, and looking to use STOAT as part of their design tool capability to support their current role or future career. Participants may also be drawn from any area of business or service where an increased understanding of process design software may impact on their decision-making and advance their professional skills in the water sector, such as wastewater treatment consultants.

As part of the course, users are encouraged to bring an example problem, to show how STOAT can be applied to their areas of concern. Having a near-future project need is also beneficial, to ensure that freshly-learned skills and guidance from our technical experts can be applied to delegates' unique scenarios.

Training outline

The course is interactive, with a mix of lecture, exercises and workshop with delegates' own examples to facilitate an engaging learner experience. The following topic areas are covered as follows:

• STOAT introduction, functionality and applications - Exercise: Overview of using STOAT to build and run a model
• Descriptions of processes and mathematical models, including exercises, for the following:
  - Influent construction (Storm tanks, Primary tanks)
  - Effects of Primary tank parameters (Activated sludge process; Oxidation ditch process; Final clarification tanks)
  - Effects of Activated Sludge parameters (SBR; Variable Volume SBR)
  - Biofilters and Humus tanks; BAFs and fluidised bed; RBCs and SBCs
  - Building a trickling filter plant
  - Sludge digestion and dewatering
• Further description of STOAT functionality - Calibration exercise: Primary tank
  
• File handling
• Bring your own works - Build a simple representation of a site of interest to you to reinforce skills learned
