AI Technical Summary

Technical Problem

Water purification systems face challenges in maintaining device dimensions and costs when dealing with increased water flow, as conventional designs require larger setups to handle higher volumes, leading to increased manufacturing and installation expenses.

Method used

A mixing and clarification device with a cylindrical tank divided by a partition, featuring inclined outlet pipes that promote floc sedimentation, allowing for efficient floc separation and reduced device size, even with increased water inflow, while incorporating a control system to manage flow rates and turbidity.

Benefits of technology

The device effectively suppresses the need for larger apparatus dimensions, reduces manufacturing and installation costs, and enhances power efficiency by promoting floc sedimentation and reducing the need for additional settling tanks, while maintaining high-quality floc formation and turbidity control.

Abstract

This mixing and turbidity-removing device comprises a substantially cylindrical tank having a bottom part, and a partition part that is provided on the inner side of the side wall of the tank and that partitions the inside of the tank into an upper section and a lower section. The partition part is provided with: a tube that has a circular opening part and that is provided on the upper side of the partition part so as to essentially have the same axial direction as the tank, the upper end of the tube being open, and the lower end of the tube communicating with the opening part, thereby allowing communication between the upper section and the lower section; an inflow pipe through which water being treated flows in; and an outflow pipe through which treatment water flows out. The inflow pipe communicates with a flow passage defined by the inner side of the side wall of the tank, the outer side of the side wall of the tube, and the partition part. The outflow pipe communicates with the tank while being inclined relative to the horizontal direction.
