AI Technical Summary

Technical Problem

Existing grit removal devices in wastewater treatment systems are inefficient, require large space, are expensive, and struggle with varying flow rates, leading to decreased grit removal efficiency and mechanical wear due to abrasive grit accumulation.

Method used

A grit removal unit with a cylindrical grit removal chamber and a grit storage chamber below it, featuring inverted truncated cone plates and concentric lamella plates that facilitate upward fluid flow, combined with a central axis and rotating blades to direct fluid and grit into the storage chamber, enhancing grit separation and collection.

Benefits of technology

The design efficiently separates and collects grit from wastewater, reduces mechanical wear, and optimizes space usage, while maintaining high removal efficiency even with varying flow rates.

Abstract

A grit removal unit includes a cylindrical grit removal chamber above a grit storage chamber, with an opening to the grit storage chamber through the bottom of the grit removal chamber. At least one layer plate is an inverted truncated cone about its central axis, spaced from the vertical wall of the grit removal chamber to allow fluid flow between them. Concentric inverted truncated cone lamella plates are supported in the grit removal chamber above the layer plates, with the lamella plates radially spaced from each other relative to the central axis.An influent opening in the vertical wall of the grit removal chamber below the stratified plates allows fluid and grit to enter the grit removal chamber, and an effluent opening in the vertical wall of the grit removal chamber above the lamella plates allows fluid to exit the grit removal chamber.
