Waste water treatment plant

Plant designed to treat household sewage and industrial wastewater. Usually consists of a mechanical cleaning step (sedimentation) and a biological or chemical step (flocculation, neutralization), followed by incineration of the remaining sludge. Continuous photometric detection is employed to check the solids content of the effluent. The free-fall flow cell is used in order to avoid window contamination.
