When I'm often asked when grease interceptors should be serviced, I wonder whether those who are asking have bigger concerns -- notably that increasing the pumping frequency of grease separators does not eliminate high FOG effluent numbers.
Testing your assumptions is always good as a pretreatment professional because so many variables impact your job. New technology and data can compel you to change some of your longest-held beliefs.
Is it possible to assume there are universally held “technical understandings” that solve nearly all fats/oils/grease issues? Are there other universally held “technical understandings” that are expected to solve TSS, BOD, pH, and other pretreatment/collection system issues? How did these “universally held technical understandings” come about and why are they still the tail that wags the proverbial dog?
This post questions a few of these universally long-held “technical understandings.”
