NSF International (www.nsf.org) developed a new protocol that is designed to address the health impact and environmental protection of septic tank and grease trap (solid and liquid) separating technology. Labrie Environmental Group (www.labrie.ca) is the first manufacturer to certify its pumping and liquid-solid separating system to the protocol.

“NSF Protocol P340: Septic Tank or Grease Trap Solid and Liquid Separating Devices” was developed for equipment that separates septic waste solids from liquids in septic tanks or grease and solids from liquids in grease traps. The protocol contains requirements to evaluate the materials, design, manufacturing, and performance of these types of equipment.

Typical servicing of septic tanks or grease traps involves transporting a large volume of water to a disposal facility. Technologies have been developed to separate the solids from the liquids in septic tanks and grease traps, and then return the treated water. P340 aims to provide a means to test the effectiveness and efficacy of these devices.
