Restrictive up flow media filter with servicing system

An upflow media filter treatment system, comprising:

• a chamber with a first end for inflowinq storm water and a second end for passing outflowing treated storm water to exit the chamber, and a floor surface;
• a flow director in the chamber to direct the inflowing storm water to flow downward toward the floor surface of the chamber;
• a media filter adjacent the second end of the chamber, the media filter comprising a media layer between at least one top lid with orifices and a bottom screen;
• and
• screens for each of the orifices in the at least one top lid, wherein downward flowing storm water approaching a floor surface in the treatment system is directed to flow upward through the bottom screen and into the media layer followed by passing through the at least one top lid with orifices restricts flow rate of the media treated storm water so inflowinq storm water has more contact time with the media layer for cleaning the inflowing storm water.

• the floor surface being a sloped floor;
• and
• a pressure water servicing system adjacent the sloped floor of the treatment system, the pressure water servicing system being used to flush captured debris toward a center of the floor so that debris is washed down the sloped floor to central locations that are easily removable by outside vacuums so that technicians are prevented from entering into chamber,
• wherein the pressure water servicing system includes:
• spray heads which pivot to be parallel to the sloped floor;
• and
• an alignment lever that allows for the spray heads to pivot to be parallel to the sloped floor.

• the at least one top lid in the media filter includes a hinge for allowing the at least one top lid to fold open for allowing servicing of the media layer;
• and
• water pressure sources directing pressurized water through the media filter when the at least one top lid is folded open to allow for backwashing of the media filter without having to remove the media layer from the media filter.

• and
• a gap between a top of the media layer and a bottom of the at least one lid, wherein the gap allows for horizontal conveyance or water flow between the top of the media layer and the orifices in the at least one lid, so that the orifices determine a rate of volume flow passing through the media filter, and the gap allowing for the media layer to shift and have movement from upward flowing water, the movement of the media layer helping preventing and breaking up clogs being formed in the media layer.

A method of cleaning a media filter in a treatment system without having to remove media from the media filter, comprising the steps of:

• providing a media filter that includes a media layer between at least one top lid with orifices and a bottom screen;
• installing the media filter in a storm water treatment chamber adjacent an outflow port from the chamber;
• receiving inflowing storm water into an inflow port into the chamber;
• directing the inflowing storm water downward into the chamber;
• directing the downward directed storm water to flow upward through the bottom screen, through the media layer and out of the at least one lid to pass through the outflow port of the chamber;
• providing a water pressure source outside of the chamber;
• opening the at least one top lid;
• and
• backwashing the media layer after opening the at least one lid to clean the media layer, without having to remove the media layer from the media filter.

A method of cleaning a water treatment system, comprising the steps of:

• providing a sloped floor in a water treatment chamber;
• providing a pressure water servicing system adjacent the floor of the treatment system;
• providing pivotal spray heads attached to the pressure water servicing system, the pivotal spray heads having alignment levers which allows the spray heads to pivot downward to be parallel to the sloped floor;
• and
• providing vertical spray heads attached to the pressure water servicing system, the vertical spray heads being perpendicular to the pressure water servicing system adjacent to the sloped floor, wherein the pivotal spray heads and the vertical spray heads being used to flush captured debris toward a center of the floor so that debris is washed down the sloped floor to central locations that are easily removable by vacuums outside of the chamber, and the vertical spray heads being used for cutting into debris bridges formed in the chamber.
