COURSE TITLE:
Microbiology of Activated Sludge. Identification and Solving of Bulking, Foaming and other Activated Sludge Process Disfunctions.

COURSE INTENDED FOR:
- Wastewater treatment plant engineers
- Wastewater treatment plant laboratory biologists and chemists
- Consulting firms
- University researchers and students interested in biological wastewater treatment

SCOPE AND METHODS:
Intensive biological wastewaters treatment processes herein referenced as wastewater biological treatment plants (WWBTPs) are mainly activated sludge and derivates, sequencing biological reactors, biological filters, trickling filters and rotating biological contactors.

The training course includes both lectures and demonstrations. Lectures are based upon paper supports (text, drawings, photos) and numeric support (PPT presentations).

Demonstrations will be made live with a microscope equipped with video image capture connected to a screen presentation, giving the possibility to trainees to bring with them samples of activated sludges from their own plants. Those samples may be very small (i.e. 50 ml), but must be representative of the mixed liquor in the aeration tank during the aeration period, and recent (no more than 48 hours, if possible kept at 4 °C)

CONTENTS:
1- Ecological background: the links between biology, physical-chemical parameters and chemical engineering:

1-1- Relevant parameters for adaptation of living organisms to WWBT processes. Influence of physical-chemical parameters on wastewater treatment biology. Adaptive capabilities of microbial ecosystems.

Applications:
-Examples of bacterial responses to environment variations in WWBTP
- Lag-time responses to externally induced perturbations in WWBTPs. Identification of causes.

1-2- Main WWBTPs bacteria and communities.
Ecosystems diversity and competition, influence of treatment processes and wastewater origin. Biofilm growth conditions and composition of exocellular polysaccharids.
Influence upon flocculation and cationic retention. Applications.

1-3- Chemical engineering approach for WWBTPs.
Main theoretical and real hydraulic configurations, parameters and kinetics characterization. Applications.

2- Filamentous microorganisms, bulking and scum production:

2-1- Filamentous growth impact on liquid - solid separation and water clarification. Bulking description and characterisation, scums classification and identification.

2-2- General characteristics of filamentous growth.
Competition with flocculated bacteria and CHUDOBA hypothesis.

Application:
Critical analysis of wastewater treatment processes parameters (bio and chemical parameters, hydraulic configuration and sludge treatment line interferences) causative of filamentous growth.

2-3- A classical case of filamentous bulking: Sphaerotilus. Main physiological, biochemical and ecological characteristics.

Application: Risk assesment for agroindustrial WWTPs.

2-4- The main groups of filamentous microorganisms and their case occurrences (the scums-, the sulfo- oxidizing- and the lightweight carbon compounds- organisms). Critical use of EIKELBOOM identification key and simplification.

Application: Preventive and curative control means and procedures. Case studies

3- Wastewater treatment microfauna:

3-1- General characteristics and role

3-2- Microfauna adaptative strategies, links with a systematic traditionnaly based upon buccal
and locomotive systems.

Application: use of an optical microscopic microfauna examination combined with the
DRAKIDES identification manual utilisation for fast diagnostic of W.W.B.T.Ps.

4-Synthesis: examples of WWBTPs ecosystems and their relations with the effluents, sewer system, plant conception and operating characteristics.
