How To Remove FOG Deposits And Prevent Sewer Overflow
Fats, oils, and grease (FOG) deposits present a problem for the wastewater industry as they create sewer lines blockages that lead to overflow. Digester systems can successfully remove these deposits with the latest environmentally friendly technology by breaking them down into microparticulates. This paper offers a technical review of the solutions available for applications such as commercial and residential lift stations, grease traps, and wet wells.

Nitrogen-Reduction Treatment Systems For Long-Term Operations
The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing
With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

Chlorine Measurement In Wastewater And Regulated Discharge Requirements
Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

Removal Of PFCs With Activated Carbon
In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

Microbial Control In Cheese Making
Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.
LATEST INSIGHTS ON WASTEWATER

Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
-
Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
-
Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.
-
Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
-
Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
-
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.
