Biological Wastewater Treatment Technology
Many companies are facing the task of having to pretreat or completely clean process effluents in their own factory
to avoid discharge fees or to lower the raw water consumption by water reusage. The majority of organic compounds are converted into carbon dioxide and water by aerobic microorganisms and can quite easily and economically be removed.
The oxygen demand of industrial wastewater is high, often between 1,000 and 10,000 milligrams of oxygen per
litre, in contrast to the low solubility of oxygen in water of only a few milligrams per litre. Therefore, the high
biomass concentration, generated by modern technologies, needs to be aerated against the pressure of the water
column. Anaerobic processes work without aeration, however, require a high expenditure for the commissioning and
ensuring a stable operation.

Technical Principle of the TFR Technology

The TFR Bioreactor works with a small lightweight carrier material which is contained within
a reactor. The microorganisms grow on the surface
of the carrier material and adapt and optimise
themselves according to the properties of the
waste water. The carrier material is not immersed
within the waste water and so it is easy to supply
the microorganisms with enough oxygen. This is
achieved by trickling waste water down through
the carrier material and blowing air up through
the carrier material with a simple ventilator.

The carrier material is stable and does not need to
be replaced. The renewable growth of biomass is
regularly removed from the system by fully automatic regeneration. The high density of microorganisms as well as ideal conditions for the mass
transfer between biomass, water pollutants and
surplus oxygen are the basis for a high and stable
biodegradation performance.
