Water Quality Management (BMEEOVKAI44)
Drinking water treatment:
The aim of the course is to introduce the different water sources, the potential contaminants and their main sources. The course will also cover the sizing of the capacity of each process of the drinking water treatment plant for both surface water and groundwater. It will also focus on the removal of different contaminants such as dissolved gases, iron, manganese, arsenic and ammonium ion. The course deals with the adverse health effects of certain water quality compounds and the possibilities to minimize their concentration in the water.
Wastewater Treatment:
The goal of the course is to master the basic concepts of wastewater treatment and getting familiar with both extensive and intensive technologies. The first lectures are expected to be interactive, discussing the matter with a holistic approach. The subject includes introductory to technologies of mechanical treatment (screening, grit chambers, primary clarifier) and types of activated sludge treatments (SBR, continuous flow, fix-filmed technologies, secondary settling); Additional topics: Plant layouts, calculation of parameters and methods for different technologies ; C,N,P removal; Deficiencies and floc formation; German planning and operating aspects -ATV-A 131 Modelling of WWTP with dynamic models; Environmental regulations.

Attendance at lectures is mandatory. Missing out more than 30% of the lectures means failing the subject.
Consultations: At the beginning of the semester at the consultation time announced on the department's website or contact the lecturers via e-mail (Souha Neguez: nagguez.souha@gmail.com; Tamás Koncsos: koncsos.tamas@emk.bme.hu).
II. Subject requirements
The learning outcomes defined in point 2.2 are assessed based on two mid-term tests, and a written and oral exam in the exam period. The exam will cover both drinking water and wastewater treatment, The students get questions related to both topics, and they need to reach minimum grade 2 (passed) in both topics.
| Evaluation form | Abbreviation | Assessed learning outcomes |
| Midterm 1 | MT1 | A1, A2, A3, A4, B1, B2, B3, C1, C2, D1, D2 |
| Midterm 2 | MT2 | A5, A6, A7, B4, B5, C1, C2, D1, D2 |
| Exam | E | A1 - A6, B1 - B5, C3, D1 |
The dates of deadlines of assignments/homework can be found in the detailed course schedule on the subject’s website.
| Abbreviation | Score |
| MT1 | 20% |
| MT2 | 20% |
| E | 60% |
| Sum | 100% |
The criterion for completion of the subject is to: collect at least 45% of the total points of the written test (MT1 and MT2) and get at least Passed (2) grade at the exam.
| Grade | Points (P) |
| excellent (5) | 85<=P |
| good (4) | 70<=P<85% |
| satisfactory (3) | 57<=P<70% |
| passed (2) | 45<=P<57% |
| failed (1) | P<45% |
It is possible to retake both mid-terms (MT1 and MT2) once for free, and one of the mid-terms can be repeated second time for extra fee.
