Wondering how to enrich or concentrate phages or viruses for community phage/virus nucleic acid extraction and that too without using host?

We all know about the specificity of viruses or phages and I guess that would specially limit their enrichment to certain groups. Suppose I have a sediment or sewage sample and I want to enrich...
