As if running a business isn’t challenging enough in the current economic climate, an invisible fallout from the pandemic may be lurking in the pipes beneath hotels and restaurants. And it really stinks.
That offensive rotten-egg smell signals the presence of hydrogen sulfide creeping up from the grease interceptor into your business. During the pandemic, we’ve had calls from clients asking about the smell, and their stories offer a helpful heads-up for all of us.
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.
Today and in the future, the link between customer and vendor will be absolutely vital. Why? Consider the struggle restaurant operators are having with hiring. It’s not just food service, either. All service industries are having trouble with staffing, including plumbing.
Restaurant businesses need vendors to step up with the kind of help we provide. We all know optimal service begins with having good customer information to begin with. That’s why we just launched a campaign to compel more customers to register their devices with us.
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.”
In the late 1980s, The Narragansett Bay Commission (NBC) provided a great example of how to maximize control when it carried out one of the most effective Pretreatment programs I've seen in my career. It had to implement an audacious pretreatment program to reduce downstream wastewater treatment plant loadings sufficient to meet the EPA’s first Marine Estuary Guidelines. The NBC was in a tough spot.
A simple, yet effective way to explain on-site pretreatment is to use a three-legged stool analogy. A three-legged stool works only when all three legs are the same length and angle and have the same strong attachment to the stool seat. If any leg is shorter, at a different angle, or loosely connected to the seat, the stool is unstable. The same is true for onsite pretreatment, with 3 key factors for foodservice establishments forming the legs.
Long periods of inactivity hurt seals, fuel systems, and moving parts of most mechanical systems. That’s why many automobiles don’t like it. Gas-powered lawn mowers and string trimmers don’t like it. Grease separators don’t like it either.
The inactivity caused by pandemic shutdowns can make some grease interceptors more hazardous to your health. Let’s find out why by taking a closer look at what happens in separators with little or no input flows.
The discourse at CWEA's annual conference was lively despite the virtual setting. Pretreatment professionals discussed ways they adapted during the Pandemic, while cities shared aggressive plans to expedite permitting processes and get commercial clients up and running again.
We speak to anyone with a FOG (fats, oils and grease) inquiry and often end up pointing them in a totally different direction than they originally were headed. It’s a pattern in these conversations. Occasionally, this involves a caller with an MGD mindset. Here is an example of how one of these calls typically proceeds.
Did you know the North American and European testing standards for certifying grease separators have nothing in common literally?
One is predominately a performance standard, a batch flow test simulating kitchen sink discharge. The other is mostly a design standard, a continuous flow test simulating floor drains receiving oily water flows.
Both tests become more difficult to pass with higher flow rates. As a manufacturer, we respect the local codes and standards. It is why we test our products to all applicable standards.
