ABSTRACT:
A purification method and device for purifying industrial liquid such as oil from contaminates including first container housing for receiving the industrial liquid in bulk and separating liquid and particulate contaminates therefrom by reversing a flow direction of the received liquid. The thus processed liquid is transferred to a second container and is subjected to a further filtration by forcing the liquid under high pressure through at least one filter element accommodated in the second container. The high pressure on the at least one filter element results in a compression of the at least one filter element thereby precluding the liquid being processed from bypassing the filter element. A further filter barrier seal element may be provided above the at least one filter element and serves as a final filtration prior to a discharge of the liquid from the second container.
