The wastewater is mixed up and equalized in one or more equalization-tanks. Furthermore hydrolyses and pre-acidification take place in these tanks. Hereafter the wastewater is delivered through a heat exchanging device into the anaerobic reactor. To protect the bacteria the anaerobic reactor is provided with an additional conditioning-tank. The function of this conditioning-tank is beside others to mix in essential micronutrients, to set up the optimal pH-value with the addition of sodium hydroxide and to provide the possibility to recirculate the water cleaned in the reactor. To ensure a constant mesophilic temperature range, the recirculated water is pumped through another heat exchanger into the reactor. |
