Aims & Issues

Unfailing Water Quality based on Early Unfailing Water Quality based on Early Warning Investigation & ExploitationWarning Investigation & Exploitation

Weaknesses in WWTPs Efficiency Management (Biological treatments, etc.)

Opportunities: Holistic approach to unfailing water quality control and Driver Indicators

When water quality fails, there are 4 possible reasons:

1. Influent Water Quality Lower than the fixed one

2. Low efficiency of some process treatment (design, management)

3. Equipment failures (maintenance)

4. A combination of above-mentioned problems
