Claim 0:
1. A coolant processing apparatus for removing sludge from a coolant discharged from a machine tool, the coolant containing the sludge flowing into a tank after chips in the coolant are removed by a filter, the coolant processing apparatus comprising:
a first reservoir provided inside of the tank and configured to retain the discharged coolant such that the sludge remains therein;
a second reservoir provided adjacent to the first reservoir and configured to retain the coolant flowing out from the first reservoir; and
a boundary wall provided between the first reservoir and the second reservoir to form a boundary therebetween against a flowing direction of the coolant,
wherein the first reservoir includes:
a flow path in which the discharged coolant flows; and
a portion provided downstream of the flow path and configured to retain the coolant therein,

wherein the flow path has at least one bend so as to bend a flow of the coolant at least once in a horizontal direction, and
wherein the boundary wall is disposed at a location downstream of the at least one bend of the flow path, the boundary wall having such a height that allows a supernatant of the coolant in the first reservoir to flow thereover into the second reservoir, while preventing the coolant in the first reservoir from flowing therethrough into the second reservoir.
