High
Nitrate Industrial Process Water
Confidential Client
Northeast USA
AQUAMEND™ water treatment technology has
been used, since 1998 for treatment of industrial
process water containing high concentrations of
nitrate. The treatment system was constructed
using tankage already present at the facility.
Operation commenced following loading of the
AQUAMEND™ biocarrier into the reactor.
This 50 gpm system has been supporting targeted
levels of treatment for the past 4 years. With
influent nitrate-nitrogen concentrations ranging
between 1,500 mg/L and 3,000 mg/L, loading rates
of 18 – 35 lbs/m3/day are consistently
observed.
As a result of strict effluent COD requirements,
the system is operated in a methanol-lean mode.
Thus, if optimized for nitrogen removal, loading
rates would be increased even higher. The
AQUAMEND™ system is a simple,
low-maintenance design which can be equipped with
automation.
