Coarse Screen Equipment for Water Treatment Projects
Coarse screen equipment is the first protection stage for water and wastewater treatment systems with large debris risk.
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
Raw water channel > coarse screen > debris removal > protected downstream process
Process flow: Raw water channel > coarse screen > debris removal > protected downstream process
