Industrial wastewater membrane selection is a process decision, not a catalogue choice. Define the water, treatment objective and surrounding unit operations before comparing products.
Characterize the wastewater
Map source streams, variability, temperature, pH, suspended solids, oils, organics, metals and salts. Identify cleaning or batch events that create peaks.
Define the separation objective
Clarification, biomass retention, particulate pretreatment and dissolved-salt reduction require different membrane processes.
Design the surrounding process
Pretreatment may include equalization, oil removal, precipitation, biological treatment or oxidation. Residuals and concentrate must be included.
Verify and compare lifecycle
Use approved technical data and consider piloting for difficult water. Compare cleaning, energy, membrane replacement, downtime and operator requirements.
