Abstract: A process for treating a water containing chlorinated organic compounds, wherein a microorganism is introduced from a degradation tank to a separation tank and an energy source is supplied to the microorganism separated in the separation tank. A water-treatment apparatus having a structure capable of continuously introducing water to be treated through a degradation tank, a separation tank and a reactivation tank. A loss of the energy source such as methane or propane discharged from the separation tank can be reduced. A water-treatment apparatus having a degradation tank and a separation tank, wherein a microorganism can be cultivated in the separation tank. The reactivation tank can be omitted, whereby the entire size of the apparatus can be reduced.

Abstract: This invention provides an oil soluble fungicide comprising a compound having the general formula ##STR1## wherein R.sub.1 is a mononuclear aromatic hydrocarbon radical comprising up to 22 carbon atoms, R.sub.2 and R.sub.3, which may be the same or different, each represents an aliphatic hydrocarbon radicals comprising up to 8 carbon atoms, R.sub.4 is an aliphatic hydrocarbon radical comprising from 8 to 20 carbon atoms; R.sub.5 is an alkylbenzene radical in which the alkyl group contains from 10 to 14 carbon atoms; and X.sup..crclbar. is a sulfonate radical.
