Case study
300 m³/d Fly-Ash Washing Wastewater Softening Project
This project treats wastewater from washing municipal-waste-incineration fly ash at a scale of 300 m³/d. Multistage softening and PEK tubular membrane solid-liquid separation connect to downstream evaporation and crystallization for wash-water treatment and water-and-salt resource recovery.
Project overview
This project treats wastewater from washing municipal-waste-incineration fly ash at a scale of 300 m³/d. Multistage softening and PEK tubular membrane solid-liquid separation connect to downstream evaporation and crystallization for wash-water treatment and water-and-salt resource recovery.
Plum’s scope of supply
Plum supplied the PEK tubular membrane system for this project. The evaporation and crystallization stage in the overall project process was outside Plum’s scope of supply.
Process route
Multistage softening → PEK tubular membranes → evaporation and crystallization
Softening reactions and tubular membrane solid-liquid separation form the treatment section upstream of evaporation and crystallization.
