ClearFlow had the opportunity to upgrade an existing Bar Screen Vault to a Comminutor Vault for the Prince William County Adult Detention Center. The upgrade reduces maintenance on the line by adding a shredder for solids. The Contractor blocked off the Bar Screen Vault, cleaned it out and removed the Bar Screen, then added the Muffin Monster shredder. The Vault was operational the same day. The Comminutor Vault is popular and necessary on prison, schools and adult care facility sites.
