SteriFix E – Continuous and reliable wastewater sterilisation
SteriFix E wastewater treatment plants are optimal for treat- ment of continuously incoming wastewater at amounts up to 120 m3/d. Using the EnviroDTS continuous process technol- ogy, the energy needed for sterilisation can be minimised by means of an effective heat recovery system.
Incoming wastewater is firstly pre-heated using the high temper- ature of the disinfected effluent leaving the plant. Directly after that, it is warmed up to the necessary sterilisation temperature using a steam injector. Due to this effective heat exchange be- tween outlet and inlet, the temperature at the discharge point is thus reached without any additional cooling. The disinfection process is monitored and regulated by the retention time and the output temperature. A sterile filter at the air vent ensures the sterility of the exhaust air. A design without dead volumes guar- antees a safe sterilisation at low operational costs. Robust and reliable equipment design results in a high availability of the plant.
