Haliscomenobacter hydrossis
The filamentous type is found in municipal and industrial plants with high nitrogen loads (dairies and meat-processing plants).
Morphology:
| Filament position: | projecting out of flake |
| Branching: | none |
| Movement: | none |
| Growth habit: | straight and needle-like |
| Aufwuchs: | absent |
| Constrictions: | none |
| Sheath: | present |
| Transverse walls: | not visible |
| Cell form: | rod-shaped |
| Length of filaments: | < 200 µm |
| Filament diameter: | 0.3 – 0.4 µm |
| Gram staining: | negative |
| Neisser staining: | negative |
Factors promoting growth:
- high nitrogen load
- high concentration of short-chain carbon compounds
- low oxygen level
- old sludge
- low phosphorous level
- oxygen deficiency
- fully mixed activation tanks
- sludge load > 0.2 kg BSB5/ kg TS * d
Countermeasures:
- setting up a plug flow or high-load zone
- brief increase to pH 9
- addition of hydrogen peroxide
