PROCESS AND APPARATUS FOR IN-SITU CLEANING OF A GAS SEPARATOR IN AN ANAEROBIC BIOREACTOR

摘要

The present invention relates to a process for in-situ cleaning of a gas-liquid separator of an anaerobic bioreactor, comprising directing a gas flow in the bioreactor in order to create a scouring effect from turbulent fluid flows resulting in the cleaning of at least a part of the gas-liquid separator. The invention further relates to a process for treating a fluid aqueous waste stream, wherein use is made of the in-situ cleaning process. The invention further relates to a bioreactor suitable for carrying out a process according to the invention.
