Apparatus for wasting flocculant sludge from clarifier
A recently granted patent (Publication Number: US11883764B2) discloses an innovative apparatus designed for efficiently removing flocculant sludge from a clarifier. The apparatus includes a wasting pipe, a manifold, upper and lower headers extending radially from a center shaft, a return sludge pipe, and a drive mechanism to rotate the headers. The upper header, positioned in the disperse sludge zone, collects flocculant sludge, while the lower header, in the settled sludge zone, collects settled sludge. The apparatus can be adjusted for optimal performance and includes features like a vacuum source for suction and a controller for directing the headers.
Furthermore, the patent also describes a wastewater treatment system incorporating the apparatus, along with additional components like a pump, a telescoping sludge valve, a composition sensor, and a drive mechanism with a second controller. The system efficiently manages the flocculant and settled sludge, directing them to waste conduits or return sludge wells as needed. The controller adjusts the height of the upper header based on measurements obtained by the composition sensor, ensuring effective operation. Overall, the system offers a comprehensive solution for clarifier retrofitting, enhancing the efficiency of wastewater treatment processes.
