Mechanical Coarse Bar Screen for Water Treatment Projects
Mechanical coarse bar screens remove large solids from wastewater or raw water intake to protect downstream pumps and equipment.
YAOTONG designs and manufactures customized water treatment equipment based on raw water quality, flow rate, suspended solids concentration, discharge standard and site conditions. This product can be supplied as a standalone unit or integrated into a complete treatment system.
Working Principle
Influent channel > bar rack interception > mechanical raking > screenings discharge > flow to downstream treatment
Process flow: Influent channel > bar rack interception > mechanical raking > screenings discharge > flow to downstream treatment
