PROBLEM TO BE SOLVED: To provide coolant filtration equipment which reduces chips accumulated on the bottom of a coolant tank as much as possible, reduces clogging of a filter, and remarkably reduces the frequency of maintenance for the filter. SOLUTION: The coolant filtration equipment is equipped with a dirty tank 11 having a chip conveyor 12. The chip conveyor 12 conveys chips in the coolant deposited on a bottom surface 19 to discharge to the outside of the dirty tank 11, and has a scraper 23 sliding on the surface of a filter plate 13 where a lot of fine hole are machined on a thin plate. The coolant filtration equipment is also equipped with an endless rotating body 29 equipped with a scraper 14 for sliding the back surface of a filter plate 13, a coolant flow path 16 for flowing the coolant after being filtered and passed through the filter plate 13 into a clean tank 17, and a clean pump 18 for pressure-feeding the coolant stored in the clean tank 17 after being filtered into a machine tool.
