Abstract: The present invention relates to a process and device for selectively removal of deflocculated sludge below a pre-selected size from a sludge mixed liquor. The invention resides in the concept of removing from the sludge mixed liquor deflocculated sludge. The removal is preferably carried out by a two-step separation providing a fraction comprising sludge flocs, substantially freed from deflocculated sludge, and a fraction containing mostly deflocculated sludge. The fraction comprising sludge flocs is returned into the sludge mixed liquor, while the fraction containing mostly deflocculated sludge is removed from the system.

Abstract: A system and method in which, upon receipt of an analysis initiation instruction and regardless of the necessity of any changes in operation at the time of the analysis initiation, an integrated controller of a system control unit notifies other units of analysis initiation and changes the luminescent color of a state indication LED to blue, which is common to each unit. In a liquid supply unit that receives a notification of the analysis initiation, a local controller changes the device status to “RUN” and changes the luminescent color of a state indication LED to blue. This is also applies to other units. Upon completion of the analysis, the integrated controller notifies each unit of the analysis completion and changes the display color of the state indication LED to green. Each unit also changes the display color of the state indication LED to green.
