Wastewater Characterization

Online Wastewater Characterization

Influent wastewater characterization technology
performs online analysis based on the
ASM (Activated Sludge Model) developed by
the International Water Association (IWA)
and the Harmony Search algorithm,
one of the meta-heuristic algorithms.
The influent wastewater characterization device
provides information that supports more efficient
and stable operation of water treatment facilities
in the field.
