In this study, a submerged aerated filter (SAF) using bottle caps as a support medium was evaluated. The system was fed with effluent from an upflow anaerobic sludge blanket system at ETE 2-South wastewater treatment plant, under different volumetric organic load rates (VOLRs). The population of a particular nitrifying microbial community was assessed by fluorescent in situ hybridization with specific oligonucleotide probes. The system showed an average removal of chemical oxygen demand (COD) equal to 76% for VOLRs between 2.6 and 13.6 kg COD m−3_media.day−1. The process of nitrification in conjunction with the removal of organic matter was observed from applying VOLRs lower than 5.5 kg COD m−3_media.day−1 resulting in 78% conversion of NH4+-N. As the applied organic load was reduced, an increase in the nitrifying bacteria population was observed compared with total 4′-6-diamidino-2-phenylindole (DAPI) stained cells. Generally, SAF using bottle caps as a biological aerated filter medium treating wastewater from an anaerobic system showed promising removal of chemical oxygen demand (COD) and conversion of NH4+-N.
Robust in operation: at Emsbüren, the AERZEN turbo saves quite a lot of energy
At Emsbüren wastewater treatment plant, Wasserverband Lingener Land invested in new blower technology for the aeration tank. In comparison with the old assembly, the turbo blower made by AERZEN saves between 100 and 200 kilowatt hours every day. Modernisation of wastewater treatment plants in order to reduce their energy consumption benefits the entire population.
Wasserverband Lingener Land has four wastewater treatment...

The wireless vibration network of Wi-care system consists of the communication between three components; the transmitter, the range extender and the receiver. The transmitter is fixed on the machine and transmits the vibration and the temperature data at the measurement point. The second element of the Wi-care wireless network is the range extender, its function is to transmit vibration and temperature data over long distances to the receiver. The third part of the communication path is the receiver/gateway which...
