About Holzwärme Flachau WWTP

The condensate wastewater from Flachau biomass power plant, with a heat output of 7 MW, is treated with the C-MEM™ process. The impurities in the condensate consisting of ash and various dissolved substances are separated in a combined precipitation / ultrafiltration, so that they can be discharged directly into the receiver. The treated water is clear, colorless and can also be reused within the power plant. In any case, the high costs for wastewater disposal are saved.

For the C-MEM™ plant, no structural changes had to be made in the cogeneration plant. The components and automation were integrated into the existing condensate basin and building to save space. C-MEM™ can cope with very high solids concentrations, inlet fluctuations, turbidity and other impurities. The fully automatic process has a power consumption of less than 0.5 kWh / m³. Other chemicals are not necessary for operation. During breaks in operation, the membrane can even fall dry and then be put back into operation at any time without pretreatment. The C-MEM ™ plant 'Holzwärme Flachau' was completely planned and built within 3 months. It has been in operation since March 2014.
