Hydrogen Sulfide: The Bad Smell That’s So Much Worse For Your Business

The Dangers of Hydrogen Sulfide

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.

How to Calculate the Total Cost of Ownership of a Grease Trap

Lifetime Cost of Grease Traps

Shopping for a new grease trap? Prices aren't what they seem. Over the life of a grease trap, what you paid upfront will become a small percentage of the total cost of ownership. To get the best value for your business over the long term, you must think of the cost in more holistic terms. Costs fall into three categories, and we outline them here to help you make the best buying decision.

How to Size a Grease Trap for a Commercial Kitchen

Correctly estimating the size of a grease trap for your project is crucial to avoid overflows, backups, and unnecessary costs. It's not easy, however. Sizing methods many plumbing codes use tend to overestimate peak flow, dictating more capacity than really needed. Those codes are based on the assumption that all fixtures in a kitchen will simultaneously experience peak flow. 

The reality is much different:

Why Lifetime Product Support Is More Vital Than Ever

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.

Stress Testing Universally Held Understandings in Pretreatment

Stokes Law

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.”

How to Exert the Maximum Influence in FOG Compliance

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.

3-Legged Stool Approach To Total Grease Management

3-Legged Stool Approach To Total Grease Management

Pretreatment’s Three-Legged Stool



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. A food service establishment (FSE) may have

Leg 1: The right grease separator and
Leg 2: Good servicing (pumping frequency and quality)

But if it has poor internal management practices (Leg 3), the FSE will send higher than allowed waste into the sewer system.

Likewise, a site skimping on pumping (Leg 2) will handicap its proper technology (Leg 1) and best management practices (Leg 3). Upcoming blog posts delve into practical information for each of these legs. We begin with Best Management Practices 101.

THIS COLUMN COULD SAVE YOUR LIFE

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.
