"biocake layer naturally forming on 10–200 μm mesh to filter solids eventually clogs/ fouls... overcome integrating piezoelectric ultrasound transducers creating microbubbles rapidly collapsing (transient cavitation), stripping away fouling... cleaning: 3.8 seconds (anaerobic conditions)/ <10 seconds (aerobic), biocake reforms <10 minutes (minimal downtime/ consistent effluent quality)... 120-day continuous filtration test, then 21-day field trial: mesh maintained structural/ mechanical integrity... scalable"
