Unfortunately, fats, oils and grease tend to pose an ongoing challenge to both wastewater collection systems and wastewater treatment plants. People cook meals, and afterward pour warm or hot fats, oils and grease right down the drain of their kitchen sinks. Additionally, some restaurants either pour large amounts of fats, oils and grease down their drains, or their grease interceptors aren’t pumped out often enough, and they overflow plenty of fats, oils and grease directly into the sewer systems.
Eventually these situations lead to the fats, oils and grease hardening on the insides of sewer pipes. This reduces the inside diameter of the pipes, which eventually get so narrow that little or no sewage can pass through them. They then back up, sometimes causing manhole covers to be lifted up by the extreme water pressure, and untreated sewage spills out onto the ground, possibly contaminating waterways and spreading diseases.
Some of the fats, oils and grease that make their way to lift station wet wells can make “flushable wipes” and other debris, stick together into large clumps, known as fatbergs. These fatbergs need to be removed manually. Any time people need to go down into manholes or lift station wet wells, there’s a possibility that one of the workers might get hurt, either from breathing in sewer gases, or experiencing a physical injury.
High amounts of fats, oils and grease also encourage the flourishing of the filamentous bacteria known as Nocardia. These bacteria are found in both collection systems and wastewater treatment plants. Because they are strictly aerobic bacteria, when they are flourishing, they use up a lot of the dissolved oxygen in the water, making it more difficult for the more preferred aerobic, floc forming bacteria to thrive. Nocardia bacteria are also notorious for creating large amounts of foam in aeration basins and digesters. Additionally, they tend to create floating sludge (known as “sludge bulking”) in clarifiers. Sludge that floats in wastewater treatment plant clarifiers, results in thick sludge spilling over the effluent weirs, and getting into the final filters. This clogs the filters quicker than usual, resulting in shorter filter runs between backwashes. Sludge spilling over the clarifier effluent weirs can also result in high turbidity in the wastewater treatment plant’s final effluent.
Furthermore, fats, oils and grease can result in unpleasant odors in wastewater collection systems, and at wastewater treatment plants. People who work around wastewater a lot, often can’t smell the odors very much. But those who don’t work around wastewater can definitely smell the strong odors, and they tend to find them unbearable, and highly offensive.
Fortunately, BioConversion Technology has a variety of solutions for problems resulting from fats, oils and grease. If you work for a wastewater collection system or a wastewater treatment plant that deals with the challenges of fats, oils, and grease in your daily operations, the experts at BioConversion Technology are happy to help you solve and ultimately prevent these problems.
BioConversion Technology sells biological and chemical products that can dissolve fats, oils and grease that have already deposited on the inside of pipes and inside lift station wet wells. For example, the company sells specific strains of bacteria that live on, and eat, annoying fats, oils and grease. By reducing the fats, oils and grease in wastewater collection systems and wastewater treatment plants, unpleasant odors naturally reduce, Nocardia bacteria don’t thrive, and both foaming and sludge bulking are likely to reduce or go away altogether. BioConversion Technology has been in business for more than 17 years.
