The removal of C12/14
amine oxide from wastewater by sewage treatment was determined in a
monitoring study in The Netherlands between May and July, 1996 [Debaere
G (1996c)]. Six municipal activated sludge treatment plants in The
Netherlands were included. The concentration of C12/14 amine oxide was
determined in influent and effluent samples. Samples (raw and treated
sewage) were collected from the six municipal activated sludge sewage
treatment plants (STP) over three consecutive days. The samples were
analysed by FI/MS/MS for both C12 and C14 Amine oxide. The removal of
Amine oxide during activated sludge sewage treatment was >95 to >99% at
the six plants. The level of Amine oxide in effluent was below detection
in all effluent samples (<0.43 µg/L). The amount of Amine oxide in
influent ranged between 9-130 ug/L. The BOD removal at the six plants
was 96 to >98%.
A second environmental
monitoring study was conducted at ten sewage treatment plants (STP)
across the[Miami Valley Laboratories (2001)].. The study included the
five most common types of STPs found in the: Activated Sludge, Trickling
Filter, Lagoon, Rotating Biological Contactor (RBC), and Oxidation
Ditch. At each of the ten STPs, samples of influent and effluent were
collected for the analysis of Amine Oxide. The monitoring was conducted
at STPs located in nine major drainage basins in the
Total AO influent
concentrations ranged from 2.3 to 28 ug/L. Total AO effluent
concentrations ranged from 0.4 ug/L to 2.91 ug/L. Percent removal of AO
varied widely (63 -97%) among sewage treatment plants (STP) sites
sampled. The variability of the influent concentrations appeared to be
largely responsible for the inconsistencies in the % removal values. The
5 plants with >90% removal had high influent levels of AO (10.5 -27.8
ug/L), while the 5 plants with <90% removal had low influent levels of
AO (2.3 -12.2 ug/L). The highest removals of AO were typically observed
at Activated Sludge STP's (up to 97%). The lowest removals (as low as
63%) were observed at Oxidation Ditches. Five of the ten STP samples had
AO removal greater than 90%.
The 3 activated sludge
(AS) plants had removals of 96, 97, and 75%. The AS plant with the
lowest removal (75%) had a low influent concentration of AO (2.9 ug/L).
The 2 oxidation ditch (OD) plants had removals of 63 and 64%. One OD
plant had a low influent level of AO (2.31 ug/L). The 2 lagoons had
removals of 95 and 86%. The plant with lower removal (86%) had a low
influent level of AO (6.3 ug/L). The 1 rotating biological contactor
plant had a removal of 94%, and the highest influent level of AO (27.8
ug/L). The 2 trickling filter plants had removals of 91 and 82%. The TF
plant () with the lower removal (82%) was operating poorly at the time
