A filter plate for removing hydrocarbons and other contaminants from solutions and gases comprises a plate provided with rows of alternate perpendicular and parallel, substantially linear openings. A liquid and gas filtering apparatus comprises a container provided with the filter plate of the invention, means for inflow and outflow of water or air and means for introducing and removing filtering materials. A method of purifying a solution or a gas comprises removing impurities by passing the solution or gas through a filtering material supported on the filter plate of the invention. A method of removing hydrocarbons and other contaminants from a solution or gas comprises passing the solution or gas through a filtering material supported on the present filter plate. A method of reducing clogging when removing contaminants from a solution comprises passing the solution through a filtering material supported on the filter plate of this invention.
A filtering apparatus for removing contaminants from a contaminated fluid, said apparatus comprising a filter plate and means for supporting the filter plate wherein the filter plate is adapted to support a filtering material, said plate having rows of substantially linear openings with at least every other of said rows being of alternating parallel and perpendicular orientation, means for providing inflow of said contaminated fluid to said filter plate and means for providing outflow of said fluid after filtering to remove contaminants therefrom.
A method for removing solid contaminants from a contaminated fluid comprising passing said contaminated fluid through a filtering material supported on a filter plate having rows of substantially linear openings with at least every other of said rows being of alternating parallel and perpendicular orientation.
