Building facades can be equipped with biocides to prevent formation of algal, fungal and bacterial films.
Thus run-off waters may contain these highly active compounds. In this study, the removal of several
groups of biocides from contaminated waters by means of an activated soil filter was studied.
A technical scale activated vertical soil filter (biofilter) with different layers (peat, sand and gravel), was
planted with reed (Phragmites australis) and used to study the removal rates and fate of hydrophilic to
moderate hydrophobic (log Kow 1.8–4.4) biocides and biocide metabolites such as: Terbutryn, Cybutryn
(Irgarol 1051), Descyclopropyl–Cybutryn (Cybutryn and Terbutryn metabolite), Isoproturon, Diuron,
and its metabolite Diuron-desmonomethyl, Benzo-isothiazolinone, n-Octyl-isothiazolinone, Dichloro-noctylisothiazolinone
and Iodocarbamate (Iodocarb). Three experiments were performed: the first one
(36 d) under low flow conditions (61 L m2 d1) reached removal rates between 82% and 100%. The second
one was performed to study high flow conditions: During this experiment, water was added as a
pulse to the filter system with a hydraulic load of 255 L m2 within 5 min (retention time

The secondone was performed to study high flow conditions: During this experiment, water was added as apulse to the filter system with a hydraulic load of 255 L m 2 within 5 min (retention time <1 h). Duringthis experiment the removal rates of the compounds decreased drastically. For five compounds (Cybutryn,Descyclopropyl–Cybutryn, Diuron, Isoproturon, and Iodocarb) the removal dropped temporarilybelow 60%, while it was always above 70% for the others (Terbutryn, Benzo-isothiazolinone, n-Octyl-isothiazolinone,Dichloro-n-octylisothiazolinone). However, this removal is a considerable improvementcompared to direct discharge into surface waters or infiltration into soil without appropriate removal.In the last experiment the removal efficiencies of the different layers were studied. Though the peat layerwas responsible for most of the removal, the sand and gravel layers also contributed significantly forsome compounds. All compounds are rather removed by degradation than by sorption.

Thus Waters Run-off Active highly May contain these compounds. In this Study, The Removal of Several
groups of biocides from contaminated Waters by means of an Activated soil Filter was studied.
A Technical Scale Activated vertical soil Filter (Biofilter) with different layers (peat, Sand and Gravel), was
planted with Reed (. Phragmites australis) and Used to Study The Removal Rates and Fate of hydrophilic to
moderate hydrophobic (log Kow 1.8-4.4) biocides and biocide metabolites Such As: Terbutryn, Cybutryn
(Irgarol? 1,051), Descyclopropyl-Cybutryn (Cybutryn and Terbutryn metabolite),. Isoproturon, diuron,
and ITS metabolite diuron-Desmonomethyl, Benzo-Isothiazolinone, n-Octyl-Isothiazolinone, Dichloro-Noctylisothiazolinone
and Iodocarbamate (Iodocarb). Three experiments were performed: The First One
(36 D) under Low Flow conditions (61 L m? 2 D? 1) reached between 82% and 100% Removal Rates. The Second
One was performed to Study High Flow conditions: During this Experiment, As a Water was added
to The Pulse Filter Hydraulic System with a load of 255 L m? 2 Within 5 min (retention time <1 h). During
this Experiment The Removal Rates of The compounds decreased drastically. For Five compounds (Cybutryn,
Descyclopropyl-Cybutryn, diuron, Isoproturon, and Iodocarb) The Removal dropped temporarily
Below 60%, while it was above 70% for Always The others (Terbutryn, Benzo-Isothiazolinone, n-Octyl-Isothiazolinone,
Dichloro-. n-octylisothiazolinone). However, this is a considerable Removal Improvement
compared to Direct discharge Into Waters surface or soil infiltration Into Removal Without appropriate.
In The Last Experiment The Removal efficiencies of The different layers were studied. The peat Layer though
was Responsible for Most of The Removal, The Sand and Gravel layers also Contributed significantly for
some compounds. All compounds are rather removed by degradation than by sorption.
