Effl uent, inoculom, and
0-8g/L sodium acetate
(organic carbon supplementation) were added
to two bacteria reactors
(HRT 1-11h)
1. Total solids (TS): according to APHA
-Method 2540 B
2. Total suspended solids (TSS): according to APHA-Method 2540D
3. VSS:according to APHA -Method
2540E
4. Total amonia nitrogen (TAN) nitriteN,nitrate-N,ortho-phosphate-P, using
the methods 155-006, 461-318,467033, 503-317 from autoanalyser
(SAN, Skalar, The Netherlands)
5. Kjeldahl nitrogen: using a Tecator
2020 Digestor and distilation by
Tecator Kjeltec Autosampler system

6. Total organic carbon (TOC) phatometrically
1. Convertion of 90%
of inorganic N and
80% of orthophosphate-P
2. Crude protein production higher than
volatile suspended
solids (VSS) production
3. Heterotrophic
bacteria production resulted in
additional protein
retention and nutient discharge

The effl uent was fed in
three glass reactors (2427°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 constructed microbial mats
1.Total ammonia nitrogen (TAN), nitrate nitrogen according to Standard
Methods (APHA), 1995)
2. Dissolved oxygen: by modifi ed Winkler method
4. pH by protentiomentry
1. 97% ammonia nitrogen and 95% nitrate
nitrogen concentration removal
2. 80% BOD 5 reduction
