Case study
3,600 m³/d PCB Wastewater Heavy Metals Treatment Project
This project treats mixed wastewater containing heavy metals from PCB manufacturing at a project scale of 3,600 m³/d. The process combines pretreatment, PEK tubular membranes and reverse osmosis, with treated water reused in production.
Project overview
This project treats mixed wastewater containing heavy metals from PCB manufacturing at a project scale of 3,600 m³/d. The process combines pretreatment, PEK tubular membranes and reverse osmosis, with treated water reused in production.
Process route
Pretreatment → PEK tubular membranes → reverse osmosis → production reuse
The PEK tubular membrane stage sits between pretreatment and reverse osmosis and provides membrane filtration within the treatment train.
