The Box-Type Lifting Screen is a robust, heavy-duty screening solution designed for wastewater channels with high solid loads. Featuring a box-shaped perforated bucket, this screen efficiently captures and lifts large volumes of solids from the flow. Constructed from high-quality stainless steel and equipped with manual lifting mechanisms, it is suitable for large municipal STPs, sewage pumping stations, and industrial effluent channels. Its sturdy design ensures long-term reliability, even under challenging conditions.
Wastewater passes through vertical bars where large solids and debris are retained. These solids are collected in the box-shaped perforated bucket at the base of the screen. Operators lift the screen using a manual winch or chain pulley system, raising the bucket along with the trapped solids. Once lifted above the channel, the perforations allow excess water to drain while retaining solids, which are then emptied at a designated disposal point. This intermittent lifting method ensures efficient debris removal, prevents clogging, and protects downstream equipment.
