Abstract

The main constructive methods for improving the process of settling suspended solids and separating sediment in horizontal settling tanks are considered. Methods for calculating these structures are analyzed both in general terms and for individual characteristic (supply, settling and drain) areas of wastewater flow. Those constructive proposals that can more significantly improve the efficiency of horizontal settling tanks are noted. The proposed modification relates to the part built into the thin-layer sedimentation tank - the flocculator, which ensures the most uniform and laminar flow in the structure.
