    To them it's just a crap,
    to us it's bread and butter.

Liquid waste reception


The facilities for receiving septic tank sludge from small wastewater treatment plants and industrial wastewater delivered by tanker trucks are located at the entrance of the plant.


Here, sieves remove the coarse particles from the wastewater. The septic tank sludge is then pumped into the digesters while the industrial wastewater is pumped into the grease and sand trap.


Next to the primary clarifier, there is a facility for receiving liquid biodegradable waste. The liquid waste passes through a sieve and a crusher before entering the hygienisation tank where heaters heat the liquid waste at 70 degrees Celsius for 1 hour before it enters into the digesters.


The CČN has obtained an environmental permit for treating liquid waste (35407-10/2014-19; 16.4.2015) / pdfpdf
