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.

AI Technical Summary

Benefits of technology

The patent text describes a grate filtration system for filtering water and debris from a water channel. The system includes two vertical grates that form a wedge shape and intersect with each other, as well as two grooved surfaces that support the grates in a vertical configuration. The grates have lowered sections near the vertex that form a spillway or a center support with grooved surfaces. The system also includes a plurality of vertical basket grates that are placed across the water channel, each with two vertical grates that intersect at a vertex and forming a wedge shape. The basket grates are placed in an offset position relative to each other to form rows. The system can also have side members that fit into side walls of the channel. The technical effects of the grate filtration system include improved water flow and reduced water channel maintenance costs.

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, resulting in oceanic contamination and pollution.

Trash and debris that flow in storm drains and other waterways not only contaminate such waterways, but also clog the waterways.

This clogging of waterways contributes to flooding and erosion, costing municipalities significant costs in trash removal, along with repairs and restoration due to erosion.

The effectiveness of such systems can be limited, particularly if they become clogged with trash and block the flow of water.
