wastewater B

TVC of biofilms (log cfu cm-2)

7.89 ± 0.52

6.39 ± 0.39

5.11 ± 0.55

TVC of planktonic cells (log cfu ml-1)

6.57 ± 0.57

Wastewater A = the wastewater containing the mineral salts and 180 ppm glutaraldehyde.
Wastewater B = the wastewater containing only 180 ppm glutaraldehyde.
*The results are expressed as mean and standard deviation during steady state.
