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.

Description

RELATED APPLICATION[0001]This Application claims the benefit of U.S. Provisional Patent Application No. 61 / 712,242, filed Oct. 10, 2012. This application hereby incorporates by reference the provisional patent application.TECHNICAL FIELD[0002]The present invention relates to a grate filtration system for filtering trash and debris from water in a storm drain.BACKGROUND[0003]The improper disposal of trash leads to accumulation of trash on streets, sidewalks, and other land areas. A largely unappreciated problem is that trash which accumulates as such can be picked up by rain and storm water, where the trash flows down street drains that lead to larger storm drains. Unless the trash and other debris that accumulates and flows in rain and storm water is removed from the water, the trash and debris can enter storm drain outlets and be flushed into rivers, lakes, streams, creeks, and other waterways. The trash and debris thereby can contaminate and pollute these waterways, the environmen...

Benefits of technology

[0042]Each basket grate 58 may be anchored in the system 56 in a manner similar to that described above for grate filtration system 10. Thus, each of the grates 62 and 64 are anchored on the outsides 66 and 68 in side pillars and at the vertex 70 in a center pillar. The pillars anchoring the basket grate 58 may be anchored into the bed of the water channel, particularly as described for the center pillar 20 in grate filtration system 10. The pillars are bolted in a similar fashion as system 20 so the pillars can be replaced if damaged. The grates are preferably mounted into grooves in the pillars, so that they are removable. This allows the grates to be removed for easier trash clean up and to be replaced if damaged. The basket grate system may likewise have a flooring member 72, to provide a smooth surface for trash removal and structural integrity. The flooring member 72 may also include grooves into which the bottom edges of the grates 62 and 64 are inserted to provide support across the bottom of the grates along with that provided at the sides.

[0043]The basket grates 58 and 60 of the basket filtration system 56 are installed so that each basket grate 58 and 60 is offset to each immediately adjacent basket, so that the baskets are staggered or offset relative to each other in the longitudinal direction of water flow in the channel, rath

Problems solved by technology

The improper disposal of trash leads to accumulation of trash on streets, sidewalks, and other land areas.

A largely unappreciated problem is that trash which accumulates as such can be picked up by rain and storm water, where the trash flows down street drains that lead to larger storm drains.

The trash and debris thereby can contaminate and pollute these waterways, the environments in which they flow, and downstream environments.

Significant amounts of trash flow to oceans
