The Vault Maintenance System (VMS) Filter Sock is designed to remove oil and sediment from underground utility vault waters. The VMS allows direct discharge of water to the environment while complying with current regulatory guidelines for TSS and Oil & Grease. The filtration system will remove visible oils and oil-borne contaminants such as PCBs and filters out suspended solids to below compliance levels for the new NPDES II regulations. Configured as a portable, easy-to-use multi-staged filter sock. Available with or without a quick-connect fitting. Quick connect fitting model also available with 5 gallon Haz-Waste Bucket.
