Abstract: A flume system for use with a floor mounted filtration apparatus and a floor mounted in-line machine section is provided. The machine section receives a flow of clean coolant from the filtration apparatus and has a series of machine outlets for outputting dirty coolant carrying particulate generated by the machine section. The system includes an elongated floor mounted flume disposed adjacent the series of machine outlets to receive the machine outputted dirty coolant. The flume has a slope of less than 2% and is coupled at an outlet end to the filtration apparatus. A discharge pipe is mounted adjacent a distal end of the flume for introducing a stream of coolant into the flume in a direction generally toward the outlet end. The stream of coolant introduced into the flume causes the flume to have an efficient hydraulic radius such that a minimal amount of coolant flows within the flume at a sufficient velocity to wash away the particulate from the flume into the filtration apparatus.
