Process
Water Containing High COD and Oil and
Grease
Confidential Client
Northwest, USA
AQUAMEND™ was used to treat industrial
process water containing spent lubricant from a
facility in the Northwest USA The investigation
focused on evaluation of the efficiency of
Adventus’ AQUAMEND™ technology for
the treatment of water containing high chemical
oxygen demand (COD) and oil and grease, with
significant concentrations of ICAP 36 metals
present in the solution.
The AQUAMEND™ treatment process is based on
the use of AQUAMEND™ biocarrier media,
which are engineered inorganic surfaces that
serve as supports for microorganisms in
bioreactor systems for the remediation of
wastewater or contaminated groundwater.
Results indicated that AQUAMEND™ treatment
reduced both COD and oil and grease
concentrations in the wastewater stream to below
the applicable criteria. The influent COD and oil
and grease concentrations were reduced from
41,700 mg/L and 2,485 mg/L to 1,130 mg/L and
<0.5 mg/L, respectively (representing
reductions of 97.3% and >99.9%). The
AQUAMEND™ system performed very well,
although the water had elevated concentrations of
several heavy metals.
