Grease Interceptor Testing

Client: Well-known grease interceptor developer

Background: Grease interceptors (also known as grease traps) are plumbing devices designed to intercept most fats, oils and grease (FOG) before they enter a wastewater disposal system. However, very large amounts of FOG from food production in kitchens and restaurants can overwhelm an interceptor, causing a release of FOG into the sewer. The materials can solidify when cooled and can combine with other disposed solids to form blockages in the sewer.  In order to minimize this risk, grease interceptors are tested before being allowed into the market.

Problem: Grease interceptors are required to pass the CSA’s B481.1-07 standard which stipulates that all units shall be tested and rated in accordance with ASME A112.14.3 prior to entering the market. The cost of obtaining this certification is approximately $20,000 with no assurance that the product will pass the test. The client did not wish to invest $20K without being confident of a ‘pass’.

Solution: Good Harbour Labs proposed running a modified version of the entire test as per CSA/ASME standards, without administering the certification, at a significantly reduced cost to the customer. GHL has the only CSA/ASME compliant test system in Canada. If the unit were to fail testing, the client could modify the product and improve performance until the product complied with all CSA standard requirements.

Steps Taken: GHL ran the test as per ASME A112.14.13. The unit did fail but the client was able to make changes and run short tests to confirm that the changes helped until the unit passed the test. The overall cost was much less than failing an official CSA test would have been.  The unit is now awaiting official CSA certification.

Result: The client was able to move forward with the official CSA standard testing with confidence.

Benefit: GHL delivered the client an improved product and peace of mind, knowing that their product will pass CSA’s certification testing.
