Carrier material for biological wastewater treatment Biological Wastewater Treatment with TFR Technology TFR stands for Trickle-Flow-Reactor , also called the trickle-flow principle. The system uses a very light, small-grain carrier material that, within days, is covered by a highly active mixed population of bacteria that is adapted to their respective conditions. Unlike commonly implemented wastewater systems, the carrier material bed is not located within a closed body of water and thus can be easily supplied with sufficient amounts of oxygen. The constant inflow of wastewater that trickles down over the bed is aerated by ambient air that is supplied by a ventilator at a minimum pressure flowing in the opposite direction.
