Patent ID: 8518246

Claim:
A device for monitoring water, comprising: a reactor, the reactor comprising a reactor chamber, a filtrate chamber, and a filter, the filtrate chamber being separated from the reactor chamber by the filter, the filter being substantially planar and inclined relative to horizontal in such a manner that gas bubbles in the reactor chamber can sweep upwards across a surface of the filter; at least one water feed line connected to the reactor chamber, the at least one water feed line being operatively configured to introduce the water to be monitored into the reactor chamber; the at least one water feed line comprising at least one pump or valve at least one water discharge line connected to the filtrate chamber, the at least one water discharge line comprising at least one valve; at least one reagent feed line, the at least one reagent feed line being connected to the reactor chamber and at least one reagent metering device; at least one measuring device for detecting the presence of microorganisms and/or the metabolic products thereof; and a controller, the controller being operatively configured to control the at least one pump or valve in the at least one water feed line and the at least one valve in the at least one water discharge line to direct a predefinable quantity of water into the reactor chamber and through the filter, the controller being operatively configured to control the at least one reagent metering device to introduce a predefinable quantity of a reagent into the reactor chamber.
