Filtering system for removing chemicals from fluids

A method for filtering a fluid stream, the method includes:

• providing a filtering system for filtering a fluid stream, the filtering system comprising:
• a housing comprising:
• an external wall;
• a top wall;
• a bottom wall;
• an internal wall adjacently spaced apart from the external wall extending from the top wall to a free edge disposed above the bottom wall;
• an influent chamber defined between the internal wall and the external wall;
• a rack extending horizontally from the free edge of the internal wall;
• and
• a settling chamber defined between the rack and the bottom wall and in fluid communication with the influent chamber for holding suspended or dissolved solids, pollutants, or nutrients filtered from the fluid stream;
• an influent pipe extending through the external wall to an upper portion of the influent chamber through which the fluid stream flows into the housing;
• an adsorbent media chamber positioned above the rack and in fluid communication with the settling chamber through the rack;
• wherein the rack separates the settling chamber from the adsorbent media chamber;
• a filtration media layer positioned in the adsorbent media chamber and on top of the rack;
• an adsorbing media layer positioned in the adsorbent media chamber and on top of the filtration media layer;
• and
• an effluent pipe through which fluid filtered by the absorbing media layer flows out of the housing;
• directing a fluid into the influent pipe;
• directing fluid from the influent pipe into the settling chamber via the influent chamber;
• directing fluid from the settling chamber upwardly through the rack;
• directing fluid from the rack upwardly through the filtration media layer;
• directing fluid from the filtration media layer upwardly through the absorbing media layer;
• directing fluid from the absorbing media layer into the effluent pipe;
• and
• directing fluid from the effluent pipe out of the filtering system.
