Abstract: A mobile clarifier system is provided. The mobile clarifier system including a trailer assembly and an inlet port. A plurality of separator cartridge assemblies is supported the trailer assembly and is configured to receive the flow of water and/or processing fluids from the inlet port. Each of the plurality of separator cartridge assemblies is configured to separate the settleable solids and the floatable solids from the flow of water and/or processing fluids and is configured to form flow zones, transition zones and calm zones. A discharge pipe system receives the settleable solids from the calm zones and conveys the settleable solids from the mobile clarifier system to downstream operations and an outlet port configured to receive processed water and/or processing fluids flowing from the plurality of separator cartridge assemblies and further configured to convey the processed water and/or processing fluids to downstream operations.
