Pls give comments & messages for Strong
Oxidiser to be used in Wastewater Treatment..

Ozone seems to be coming on very strong in wastewater
treatment.

... as a disinfectant, and

... in control of filamentous bulking, even reduced the sludge
that had to be sent to a dump.

But surely it is not so good at reducing BOD -- which is his
concern.

Well ...
* Ozone reduces BOD by some (usually small) amount.
* Ozone reduces COD, so the biota can concentrate on BOD for
survival.
* Ozone (properly applied) kills organisms that take a long time
to establish themselves, so that the organisms that consume
(rather than produce) BOD can thrive.
* Ozone can (properly applied) lyse the fat stores from
organisms, so that they must seek additional food for survival.

Ozone is not a panacea, but it is commerically available, and
might be less tempermental than what he keeps asking about.

Oh, ozone-in-solution is commerically used to rinse out wine and
beer casks / staves, to restore the "woody" characteristic so
they can be rapidly reused.
