Investigating an advanced method of surface runoff treatment in the city of Sochi

Summary

The results of investigating storm water treatment technologies under the conditions of Sochi are presented. A pilot treatment plant is described, the operation of the basic units – lamella settler and filters – is considered. The kinetics of surface runoff suspended solids sedimentation is investigated. The performance characteristics of the lamella module during chemical sedimentation: downward clarified water flow rate in cavities, upward flow in plate spacing, and water surface loading were determined. The efficiency of using fibrous filter for storm water treatment was theoretically substantiated and studied. The service adhesive capacity of the filter was determined. The methods of the treatment unit regeneration are suggested.
