Abstract
A filtration device has a primary conveyer tank which is equipped with a first conveyer, a primary drum filter which rotates inside the primary conveyer tank, a secondary conveyer tank which is equipped with a second conveyer and a secondary drum filter which rotates inside the secondary conveyer tank. Liquid in the primary conveyer tank passes through a first opening to flow into the secondary conveyer tank. Clean liquid flowing into a first clean tank is supplied to a low-pressure-side supply system by a first pump. Super-clean liquid having been filtered by the secondary drum filter passes through a second opening to flow into a second clean tank, and then is supplied to a high-pressure-side supply system by a second pump.
