Endocrine disrupting compounds, EDCs, are recently recognized
pollutants which interfere with the hormonal systems of
animals. At the extreme end are known to cause gender shifts
and reduced fecundity in fish. Their possible interference with
the water cycle thereby affecting humans has been implicated.
Current view in combating EDCs in water cycle is the multi barrier
approach. Where EDCs are tackled in effluents, the environment,
and in potable water supply. Therefore, information on their

the future. Fivedifferent EDCswereselectedasmodel compounds
for monitoring in seven selected treatment plants; two natural
hormones: estrone and progesterone, exclusively discharged
by humans. Carbamazepine, diltiazem and acetaminophen are
pharmaceuticals often detected in wastewaters at ppb levels. The
24 h composite samples were analyzed in influents and effluents
of various modifications of conventional activated sludge (CAS)
and one membrane, MBR (Membrane bioreactor), plant. One
striking finding was the removals obtained in conventional plants,
which were far exceeding those obtained in the mid-scale or lab-
scale MBR plants. The hydrophilic species were found amenable
to biological treatment whereas the two strongly hydrophobic
chemicals (KOW>4), carbamazepine and diltiazem, were
effectively removed by the CAS process mainly by sorption onto
sludge, whereas the MBR plants were unable to remove these
compounds from effluents, not even by sorption onto sludge.
This is a cause for concern as MBRs are considered the future
generation of wastewater treatment since their effluents are
sparklingly clear and disinfected, hence suitable for reuse. An
ozone assisted aerobic sludge digestion process developed in the
lab provided >99% EDCS removal at reasonable cost.
