Abstract
A fluid distribution system for directing fluids through a filter system. The fluid distribution system ensures proper distribution of fluids during the process of filtering as well as the process of washing a filter bed. The fluid distribution system may be used with numerous filter systems including but not limited to an upflow filter, a downflow filter, a combined upflow/downflow filter and/or multiple downflow filters connected in series.
Claims39
An apparatus for use in a filter system for filtering water or wastewater, said apparatus comprising:
- (a) an underdrain, said underdrain having at least one chamber;
- (b) a porous plate;
- and,
- (c) at least one support arm for supporting said porous plate in fixed relationship relative to said at least one chamber, said support arm having means for permitting said porous plate to be readily removed from said support arm.
A method of enhancing an existing underdrain of a filter system for filtering water or wastewater, comprising the steps of:
- (a) providing an existing underdrain of a filter system for filtering water or wastewater, the existing underdrain including a first chamber;
- (b) providing an underdrain cap having a least one support arm for receiving a porous plate;
- (c) securing the underdrain cap to the existing underdrain to form a second chamber which communicates with the first chamber;
- and,
- (d) providing at least one porous plate to obviate the need for one or more media support layers.
An apparatus for use in a filter system for filtering water or wastewater, said apparatus comprising:
- (a) an underdrain;
- (b) an underdrain cap secured to said underdrain;
- and,
- (c) an air distribution conduit detachably connected to said underdrain cap.
An apparatus for use in a filter system for filtering water or wastewater, said apparatus comprising:
- (a) at least one underdrain block;
- and,
- (b) an air distribution conduit detachably connected to said underdrain block.
An apparatus for use in a filter system for filtering water or wastewater;
- said apparatus comprising:
- (a) an underdrain;
- and,
- (b) an underdrain cap secured to said underdrain, at least one fluid distribution chamber being formed between said underdrain and said underdrain cap, said underdrain cap having means for receiving at least one porous plate.
An apparatus for use in a filter system for filtering water or wastewater;
- said apparatus comprising:
- (a) at least one liquid distribution chamber;
- (b) at least one air distribution conduit;
- (c) a porous plate, said at least one liquid distribution chamber being disposed entirely below said porous plate;
- (d) at least a portion of said air distribution conduit extends above said porous plate;
- said air distribution conduit having at least one exit opening where air exits the at least one air distribution conduit, said at least one exit opening is disposed below said porous plate.
An apparatus for use in a filter system for filtering water or wastewater;
- said apparatus comprising:
- (a) at least one liquid distribution chamber;
- and,
- (b) at least one air distribution conduit, said air distribution conduit having upper and lower portions, said air distribution conduit having internal flanges to permit liquid to be evacuated from the air distribution conduit at said lower portion.
An apparatus for use in a filter system for filtering water or wastewater;
- said apparatus comprising:
- (a) at least one liquid distribution chamber;
- and,
- (b) at least one air distribution conduit having upper and lower portions;
- (c) a porous plate, said at least one liquid distribution chamber being disposed entirely below said porous plate;
- and,
- (d) said upper portion of said air distribution conduit being disposed above said porous plate, said lower portion of said air distribution conduit being disposed below said porous plate.
An apparatus for use in a filter system for filtering water or wastewater, said apparatus comprising:
- (a) an underdrain, said underdrain having at least one chamber;
- (b) a porous plate;
- and,
- (c) at least one support member for supporting said porous plate in fixed relationship relative to said at least one chamber, said support member having a weakness point for permitting said porous plate to be readily removed from said support member.
