Principles
of Operation
EBD
Water sewage treatment plants utilize the
extended aeration process for the
reduction of the Biological Oxygen Demand
(BOD) loading, being the main regulated
discharge parameter.
By providing sufficient oxygen levels and
mixing, the microorganisms are allowed to
breakdown the organic impurities in the
raw sewage.
Secondary treatment is achieved using the
Pre-Engineered EBD Water package plants.
These package plants produce treated
effluent levels of 20 mg/l BOD and 30 mg/l
suspended solids. This is featured
through a five-step treatment process:
Comminution and screening, diffused
aeration, clarification, sludge
recirculation and disinfection.
Tertiary Treatment and Advanced Wastewater
Treatment (AWT) are further options to
improve the discharge qualities.
EBD Water multi-media Filtration Systems
are used to achieve the tertiary treatment
levels of 10 mg/l BOD and 10 mg/l
suspended solids.
Further treatment, using technologies such
as Coagulation, Flocculation, Reverse
Osmosis and Ion-exchange produces water
for reuse and recycle in all applications.

EBD Water offers a variety of sewage
treatment plants, handling raw sewage
from various sources, producing
different discharge qualities to meet
each of the specific local requirements,
all however meeting the international
environmental standards.
