Preferment Package With Spiral Flow Grit Removal System

摘要

The present invention relates to a comprehensive pretreatment device such as water, sewage and wastewater,;Inflow water consisting of water, sewage, and wastewater is introduced into the microbar screen unit, and the contaminants contained in the inflow water are collected and separated by a microbar screen, and collected by a compression dewatering screw conveyor, while the dewatering filtrate is returned to the inflow channel.;The inflow water passing through the micro bar screen part is introduced into the circular sedimentation tank part, and the supernatant water is discharged to the aftertreatment device through the outflow path by centrifugal force by the impeller, and the sediments such as soil or sand are collected in the center, and the tornado block is installed at the center. After rising to the top by the tornado generated in the;By spraying the washing water with high pressure on the sediment, the suspended solids are separated and the washed sand is collected by the inclined screw conveyor.;This is a consistent pretreatment process that allows for more efficient separation and removal of contaminants and sediments from the influent.
