Description
Duration: 5 days
The main purpose of the five day Advanced Design Course Part I is to help you master the optimized wastewater treatment plant design procedure for the most commonly used nitrogen removal systems: i.e. pre-D and Bardenpho configurations. A method is presented which ensures optimized design for situations with or without complete nitrogen removal.
As a first step the basis of the activated sludge process will be explained: the steady state model for COD removal. The sludge age is introduced as the key parameter defining activated sludge system performance, including excess sludge production and oxygen demand. We will then focus on the design of the main units of the activated sludge system: aeration tank, final settler, sludge thickener, anaerobic digester and aeration equipment.
An important part of the training will deal with common problems experienced during the design process, e.g. dealing with uncertainties (e.g regarding peak loads and flows).
Among others the following subjects will be adressed:
- Measuring organic material in wastewater
- Bacterial metabolism
- Setting up and closing mass balances over an activated sludge system
- Steady state model for COD removal
- Concepts in nitrogen removal
- Nitrification and denitrification
- Optimized design of nitrogen removal
- Operation and -control of nitrogen removal systems
- Final settler design - solids flux theory
- Sizing of aeration capacity
- Sludge thickening
- Anaerobic digestion
- Preparation of the basis of design
- Unit costing
- Integrated design of activated sludge systems

This course will be given in intensive full-day sessions (from 8:30 to 17:30 hrs), in a mixture of presentation of theoretical concepts, design- and calculation examples and short- and longer exercises to work on: both in-class and as homework assignments.
The days will start with a summary of yesterdays main learning points and a discussion on the homework assignment(s), handed out the previous day. Part of the homework assignment will be a multiple choice test, which will be used to check whether the concepts presented have been sucessfully conveyed.
At the end of the course, the students will be provided with a practical design case, which will serve as an "examination". A spreadsheet for optimized design of nitrogen removal is supplied that can be used as a starting point. The students are expected to finalize the design case at home. They will receive feedback on their results and a spreadsheet containing the solution.
You will receive a attendance certificate of 80 hrs for Advanced Course Part I, if you participate the whole course and hand in the multiple choice exams. Assuming you produce a “workable” solution to the design problem, you will get a graduation certificate as well.
We will supply you with a copy of the Handbook and detailed printed handouts of the presentations. For Advanced Design Course Part I, although not strictly required, we suggest you study in advance the following parts of the Handbook, which can be downloaded from the website:
- Chapter 2
- Section 3.1 - 3.2
- Section 4.1 - 4.4
Please note that fluency in English is essential to make your attendance to the course worthwile. Furtherwore it is assumed that the attendees have at least basic knowledge of wastewater treatment design and/or operation. Course will be given at BSc/MSc level or equivalent.
