CE 705 Activated Sludge Process Didactic Equipment Vocational Training Equipment Process Control Trainer
Wastewater treatment plant in laboratory scale: aerobic biological degradation of organic substances, system control via PLC Features - aerobic biological degradation of organic substances - nitrification and pre-denitrification - device control using an integrated PLC - integrated router for operation and control via an end device and for screen mirroring on additional end devices: PC, tablet, smartphone Learning objectives/experiments - learning the fundamental principle of the activated sludge process - functional principle of nitrification and pre-denitrification - creation of a stable operating state - identification of the following influencing factors -- return sludge ratio -- reflux ratio of the internal recirculation -- sludge age -- sludge loading -- volumetric loading -- oxygen concentration and temperature - efficiency of the pre-denitrification - screen mirroring: mirroring of the user interface on end devices -- menu navigation independent of the user interface shown on the touch screen -- different user levels available on the end device: for observing the experiments or for operation and control Specification [1] aeration tank divided into two areas [2] secondary clarifier with sludge scraper [3] nitrification and pre-denitrification [4] separate supply unit with 2 stirring machines [5] control and measurement of temperature, oxygen concentration and flow rate [6] measurement of pH value in the aeration tank [7] ectromagnetic flow rate sensors [8] device control with PLC via touch screen [9] integrated router for operation and control via an end device and for screen mirroring: mirroring of the user interface on up to 5 end devices [10] data acquisition via PLC on internal memory, access to stored measured values via WLAN with integrated router/ LAN connection to customer's own network
