Sand Catching Chamber of an Improved Design

Summary

An improved design of a chamber meant for catching of large fractions of pollutants of mineral origin (sand) by means of their sedimentation is offered. The chamber makes it possible to increase the transporting capacity of a surface wastewater flow in large collectors of a water disposal system without disturbance of its hydraulic conditions and sedimentation of suspended organic particles. A simple and economic scheme of sludge removal from the chamber is presented.

Key words

surface runoff , coarse-dispersion admixtures , dragged particles , dragged particles , sand catching chamber , hydraulic condition
