ABSTRACT:
A filter unit using a bump-type filter is disclosed. Briefly stated, a chamber has a split fluid inlet conduit so that contaminated fluid, upon entering the chamber, is directed upwardly towards filter tubes and downwardly towards the bottom of the chamber. The fluid flow is diverted during startup so as to be directed only downward thereby enabling precoat of the filter element. Two tube sheets are utilized with incoming fluid in the vertically upward inlet conduit forcing incoming contaminated fluid to be deposited between the two tube sheets thereby. During operation contaminated fluid flows upwardly and downwardly towards the filter tubes so as to prevent disturbance of filter tubes as a result of turbulence in the chamber.
