Grate filtration system

Abstract

A grate filtration system filters trash and debris from water flowing through a water channel by way of two vertical grates that intersect at a vertex and form a wedge shape that protrudes into the direction of flow of water in the channel. The grates are removably supported in grooves on side and center pillar supports. The vertical grates provide a spillway near the vertex. The system further includes a concrete apron that provides a smooth surface for the system and has grooves to support and retain the bottom edges of the vertical grates.

1 . A grate filtration system for filtering water and debris from a water channel comprising:
 two vertical grates that intersect at a vertex and form a wedge shape that protrudes into a direction of flow of water in the channel; and   two grooved surfaces, one on each side of the channel, that removably support the vertical grates in a vertical configuration.   
     
     
         2 . The grate filtration system of  claim 1 , wherein each of the vertical grates has a lowered section near the vertex, wherein the lowered sections comprise a spillway at the vertex. 
     
     
         3 . The grate filtration system of  claim 1 , further comprising a center support at the vertex of the vertical grates, the center support comprising two grooved surfaces that removably support the vertical grates in a vertical configuration. 
     
     
         4 . The grate filtration system of  claim 1 , further comprising a concrete apron on a bottom surface of the water channel and upon which bottom edges of the vertical grates are positioned. 
     
     
         5 . The grate filtration system of  claim 4 , wherein the concrete apron has grooves that removably support the bottom edges of the vertical grate. 
     
     
         6 . The grate filtration system of  claim 1 , wherein the vertical grates comprise bars that are configured to promote water flow toward sides of the vertical grates and the water channel, away from the vertex of the vertical grates. 
     
     
         7 . The grate filtration system of  claim 1 , further comprising side members, one on each side of the channel, wherein each side member is constructed to fit into a side wall of the channel, and wherein each side member has one of the two grooved surfaces that removably support the vertical grates in a vertical configuration. 
     
     
         8 . A grate filtration system for filtering water and debris from a water channel comprising:
 a plurality of vertical basket grates placed across the water channel, each vertical basket grate comprising two vertical grates that intersect at a vertex and forming a wedge shape that extends downstream with a direction of flow of water in the channel; and two grooved surfaces, one on each outside of the vertical grates that removably support the vertical grates in a vertical configuration;   wherein the plurality of vertical baskets are placed across the water channel so that each vertical basket grate is in an offset position in a longitudinal direction of water flow in the channel relative to the basket grate adjacent to it; and wherein the offset position alternates between being forward and rearward in the longitudinal direction of the water channel to form a first row of vertical basket grates and a second row of vertical basket grates.   
     
     
         9 . The grate filtration system of  claim 8 , wherein each vertical basket grate further comprises a center support at the vertex of the vertical grates, the center support comprising two grooved surfaces that removably support the vertical grates in a vertical configuration. 
     
     
         10 . The grate filtration system of  claim 8 , further comprising a concrete apron on a bottom surface of the water channel and upon which bottom edges of the vertical basket grates are positioned. 
     
     
         11 . The grate filtration system of  claim 10 , wherein the concrete apron has grooves that removably support the bottom edges of the vertical basket grates. 
     
     
         12 . The grate filtration system of  claim 8 , wherein the vertical basket grates comprise bars that are configured to promote water flow toward the vertex of the vertical grates. 
     
     
         13 . The grate filtration system of  claim 8 , wherein the vertical basket grates comprise  3  or more rows. 
     
     
         14 . The grate filtration system of  claim 8 , wherein the grate filtration system comprises  5  vertical basket grates in two rows.
