Effl uent, inoculom, and
0-8g/L sodium acetate
(organic carbon supple-
mentation) were added
to two bacteria reactors
(HRT 1-11h)
1. Total solids (TS): according to APHA
-Method 2540 B
2. Total suspended solids (TSS): accord-
ing to APHA-Method 2540D
3. VSS:according to APHA -Method
2540E
4. Total amonia nitrogen (TAN) nitrite-
N,nitrate-N,ortho-phosphate-P, using
the methods 155-006, 461-318,467-
033, 503-317 from autoanalyser
(SAN, Skalar, The Netherlands)
5. Kjeldahl nitrogen: using a Tecator

6. Total organic carbon (TOC) phato-
metrically
1. Convertion of 90%
of inorganic N and
80% of orthophos-
phate-P
2. Crude protein pro-
duction higher than
volatile suspended

duction
3. Heterotrophic

The effl uent was fed in
three glass reactors (24-
27°C, pH 7.8-8.0, oxygen
concentration 8 mg/L
and HRT 5 days), each
one of them consisted of
a retention chamber, and
three stages with the con-
structed microbial mats
