Project location An Iron factory in  Tangshan
Project time August 2012
Project condition Raw water is the coastal groundwater. UF system is made up of nearly 300 modules and has been working for 4 years. The system is running for nearly four years. 75% of membrane modules are leakage.  The product water quality has been not up to standard.
Maintenance and service items Online testing membrane module leakage and mending, ensuring treated water meet the production standard.
