The F.O.T process already contains a flocculation filtration system, so that future editions require no more further investments. The filtration reduces the settleable solids to values under the detection limit and total phosphorus to values under 0,05 mg/l. The process also eliminates bacteria, viruses and hormones. The waste water will be efficiently disinfected and sanitised. This advantage for water and environment protection pays itself out by a decrease of the sewage duty. Beyond that the procedure corresponds in its entirety to the agenda 21.

The system was brought from the year 1996 to 2003 to the marketability. The process bases on the fundamental idea that the liquid/solid separation is the cheapest and most reliable form of  waste water treatment. The process suitability was proven with three pilot plants which were dimensioned  for 1,000 inhabitants and worked more than 12 months satisfactorily .

All components and assemblies of the procedure have proven themselves for many years in large-scale technically.

In Germany the F.O.T process was offered for four municipal advertisings. With three advertisings was our suggestion with a projection of offer cheapest up to 35%. The 4-th advertising was more favourable even 40% than standard waste-water procedures, provided that the operator renounces the use of standard grease,fat and particle separation, which is unneeded for the FOT process. Besides, is to be taken into consideration that the FOT process is already dealing with the elimination of bacteria, viruses and hormones as well as many other organic and inorganic contaminants, which are not be treated by the other offered standard waste-water treatment systems. All our offers are made professionally in collaboration with leading German engineering companies.

The calculations are based on the present results of the large-scale technical pilot plants and contain to our conviction still large security reserves whose figures must be allocated, however, still experimentally. In addition, far-reaching developing potentials still exist.
