ECTS

Prerequisites

Attendance at SE-AWW1

Main purpose

Through information retrieval, discussions, presentations and laboratory exercises to provide the student with knowledge in planning establishment and design a proper waste water treatment plant (WWTP) for achieving a current wastewater quality.

Knowledge

Knowledge of designing basic treatment facilities in order to remove grease and oil, sand and gravel, suspended solids, organic matter and ammonia.
Establishing of a simple flow diagram and understanding of the internal relations between functions
Knowledge of hydraulic demands within the individual cleaning functions as well as the whole plant
Composition of wastewater and its significance in wastewater treatment
Recognition of wastewater cleaning methods related to the different wastewater treatment methods
Ability to find the right design of WWTP according to the actual outlet demands and geological conditions.
Possible cleaning achievement from the different treatment methods and systems.

Skills

Able to design a mechanical – chemical and biological WWTP
Able to describe necessary supervision and control of a WWTP
Calculation of volume of sand and grease trap
Calculation of primary settlement tank
Calculation of biological tank with nitrification
Calculation of secondary settlement tank

Competences

Knowledge about treatment methods and their depending’s of previous treatments of the wastewater
Comparing different treatment systems and able to choose the right one for the actual case
Design treatment functions applying methods in order to reduce energy consumption
Use optimal hydraulic design in order to avoid unwanted settlement within the system
Analyze a specific wastewater flow and outlet demands in order to establish the necessary treatment plant
Explain the design criteria from an environmental point of view, create a flow diagram, and plan drawing of the WWTP according to this.

Topics

Design various elements of WWTP including mechanical – chemical and simple biological processes in order to achieve the requested outlet demands.
Achieve basic knowledge of methods to ensure optimum and environmentally friendly buildings, mechanical and electrical equipment and working qualities.
Understand basic principles of supervision and control of WWTP.
Understand the hydraulic function and interaction within the separate functions as well as in the entire plant.

Teaching methods and study activities

Individual information retrieval, data analysis, report writing, discussions in groups assisted by the lecturer, presentations, self-study, homework assignments.
137.5 hours of work for the student.

Study Activity Model

According to the Study Activity Model, the workload is divided as follows:
Category 1, Initiated by the lecturer with the participation of lecturer and students: 37,5 lesson – 27%
Category 2: Initiated by lecturer with participation of students: 40 hours – 29%
Category 3: Initiated by students with participation of students: 40 hours – 29 %
Category 4: Initiated by students with the participation of lecturer and students: 20 hours – 15%
