Using coagulation to restrict microbial re-growth in tap water by phosphate limitation in water treatment

- Adding different nutrients showed the investigated tap water was phosphate limited.
- Most of the re-grown bacteria (>85%) possessed high nucleic acid content.
- It was shown for the first time that coagulation has a major influence on MRP.
- The required dose for shifting the limitation regime from C to P was different for different coagulants.
