ABSTRACT:
For the biological purification of wastewater in a reactor in the presence of open-pore and compressible carrier material for biomass, the carrier material, prior to its use in the reactor, is loaded with bacteria, finely divided, inorganic and/or organic compounds, selected for wastewater purification, and is then either stored or used in the process, the loaded carrier being especially useful for decreasing the start-up time of a wastewater treatment plant.
