MULTIGUARDTM is a bar screen that removes high solids loads of bulky coarse material in the wastewater. It is the first cleaning stage in municipal and industrial wastewater treatment plants and protects equipment downstream.
MULTIGUARDTM consists of screen bars with either rectangular or tapered profile and spaced to suit individual requirements. Made from stainless steel. The screening bars usually end above the top water level and continue with solid debris plates to the discharge point.
The cleaning elements are machine rake teeth that are fixed to multiple carrier beams. The beams are connected to two strands of chains that can easily be tensioned and as the majority of maintenance activities take place at cope level downtime is minimised due to reduced maintenance requirements.
The chains pass around a bottom shoe, but a sprocket can be provided if required. Drives can be weatherproof or zoned for gas areas and are shaft mounted to give clean lines to the screen.
The debris on the rakes is removed by a pivoted wiper with a wear-resistant U.H.M.W.P.E blade.
Screens can be up to 13ft(4m) wide in a choice of materials and are suitable in channels up to 39ft (12m) deep.
