Preface
The wastewater system described below was designed as a
COD mining plant operated without sewage sludge preparation.
Commissioning: 1999
The wastewater pollution from the albi fruit juice production
amounted to approx. 136m³ / day
from 2,000 mgO2 / l to 8,000 mgO2 / l
Running time 24 hours, input approx. 5.6 m³ / h,
COD reduction up to 975 kg COD / day
Using a sludge filter press would produce around 700 kg
of sewage sludge per day attack. This sewage sludge filtration
is not installed because the municipality
Before planning this wastewater treatment plant, the reduction
of the wastewater content had agreed, but the hydraulic load
was supposed to reach the municipal sewage system.
The complete sewage treatment plant consists of the f

Ventilation states
Specific oxygen input is 17 gQ (Nm³ + mET)
Entry depth in the basin: 3.5 m
There are 2 concrete pools built,
LxWxH = 18.05 m x 9.025 m (per chamber) x height 5.5 m
Water depth max. 4.3 m, min. 3.07 m
Due to different wastewater inflow volumes
during the day, the aeration system with different
operated water levels.
The waste water is fed with a pressure line in DA 90,
the discharge from the aeration tank is max. 3 liters / sec.
The flow rate is determined by a flow measurement and control slide
