Operating Manual for SBR small wastewater treatment systemsKLbasic controlKLplus controlFigure 3 : View of the KLbasic control unitFigure 4: View of the KLplus control unitDisplay of the operating statesThe operating state of the plant is displayed by the light-emitting diode (green = operation / red = fault)and as text on the LC screen.In the normal operating mode (ventilation mode), the liquid crystal display is as follows:Aeration120.10maerationrest: 120.10 MinFigure 5: View of the liquid crystal display during the ventilation phaseIn the automatic mode, the liquid crystal display indicates the current working phase and the remainingtime of this work step.If a fault occurs, the message at which component the fault occurred (e.g. fault compressor) appears onthe liquid crystal display. Note: The correct behaviour in the event of a fault is described in more detail in section 8.The following work phases are displayed:KLbasic display Performed process KLplus displayCharchng Valve 1 is driven; the feed lift conveys wastewater to chargingbe treated from the sludge storage into thebioreactor.Denitrif Valve 2 is intermittently driven; the activated sludge denitrificationis briefly mixed with the wastewater. This process isfollowed by long pauses (reaction times).Aeration Valve 2 is driven; the bioreactor is aerated at aerationintervals.Sediment No valve is driven, the activated sludge settles in the sedimentationbioreactor.Discharc Valve 3 is driven; the clearwater is pumped into the dischargingoutlet.SludgeRe Valve 4 is driven; the reactor pumps the excess sludge returnsludge into the sludge storage.Pause Valve 2 is driven; the bioreactor is aerated at cycle pause14KLARO GmbH
