Cleaning
An essential part of high-pressure cleaning are the cleaning nozzles.
This module covers the complex task of choosing the optimal cleaning nozzle for the respective application, as there are a multitude of nozzle types with different features available.
After completing this module, you will have a sound knowledge of:
LEARNING OUTCOMES
- The physical mode of action of pressurized water jets;
- Selection of cleaning nozzles depending on the cleaning task and
- Assessment and recognition of application risks.

Drain and sewer may only be used in such a way that any avoidable impairment of groundwater and water bodies is eliminated. The solid’s physical properties and the sewer system’s hydraulic condition dictate whether they will reach the sewer treatment facilities or be deposited in the sewer line. The latter is the subject of this module.
After completing this module, you will have a sound knowledge of:
LEARNING OUTCOMES
- The origin of solids and their transport characteristics;
- The consequences of solids discharge for the operation and maintenance of drain and sewer systems.

Depending on the boundary conditions, different types of vehicles are used for high-pressure cleaning.
This module provides a detailed overview of the cleaning vehicles and familiarises you with the central process sequences and the diverse vehicle technology.
After completing this module, you will have a sound knowledge of:
LEARNING OUTCOMES
- Cleaning vehicle components and how they work;
- Cleaning process flows; and
- Operational restrictions.

This module deals with the topics of semi-centralized and decentralized sedimentation of solids. One focus is on decentralized sedimentation using road catch basins. The different designs and modes of operation of these structures are explained and their performance is demonstrated.
After completing this module, you will have knowledge regarding:
LEARNING OUTCOMES
- Constructive measures to prevent sedimentation;
- Procedural principles of these constructive measures.

In addition to an introductory overview of the various flushing methods and the criteria that must be taken into account when selecting these measures.
This module focuses thematically on the physical properties of shafts and the different designs of flushing methods.
After completing this module, you will have a sound knowledge of:
LEARNING OUTCOMES
- Process sequences in surge flushing;
- Influences on the efficiency of bed-load and suspension waves;
- Differentiation of surge flushing devices according to their constructive design or technical equipment;
- Process sequences in back-up flushing and their application limits.

This module focuses on the different possibilities for mechanical cleaning of sewers. In this context, a wide range of mechanically operating cleaning equipment is presented, and a practical impression is given.
After completing this module, you will have knowledge regarding:
LEARNING OUTCOMES
- Methods of mechanical cleaning and their areas of application;
- Allocation of mechanical cleaning methods depending on the boundary conditions (diameter, type and quantity of deposits, obstacles);
- Areas of application for the use of physical, chemical and biological methods.
