Prefilter
14 listings from 5 suppliers
Japanese name: プレフィルター
Prefilters sit upstream of the main filter to remove particles and aggregates, reduce fouling and protect the downstream membrane. They secure flow in clarification and nanofiltration steps. Buyers consider the structure, such as depth or adsorptive type, the retention capacity and the particle size range targeted. Listings cover general prefilters for particles, turbidity and aggregates, prefilters dedicated to virus removal filters, and clarification depth filters used ahead of the main step.
