Wastewater Plant In Como, Italy, Upgrades To De Nora Ozone For Significant Savings
The Lariana Depur wastewater treatment plant in Fino Mornasco, Italy, treats wastewater from multiple textile manufacturers in the Como region, known as the heart of the textile industry. Since 1994, ozone has been used effectively as a polisher to remove the dark blue-purple color — the result of the dyes used in the textile dyeing and printing process — from the water.

Supplemental Aeration System Reduces High BOD Levels And Solves Odor Issues
A leading fruit juice company had expanded over the past ten years and increased wastewater flow from 7,000 to 11,000 gallons per day (gpd), without upgrading its wastewater treatment plant. Read the full case study to learn how after a Mazzei AirJection system was installed, dissolved oxygen levels increased in the aeration basins, which immediately eliminated the odors.

Mixers Clear FOG And Reduce Operating Costs By More Than 80%
The Cypress Creek WWTP in Florence, AL, uses an extended aeration activated sludge process with a design capacity of 20 million gallons per day (MGD). Cypress Creek serves mostly residential customers, but about 15 percent of its influent comes from industrial sources, and their discharge to the plant contains large amounts of fats, oils, and grease (FOG).

Using Ozonation And Biologically Active Filtration To Remove Micropollutants
Ozonation and biologically active filtration (O3-BAF) is being increasingly used to address the issue of organic micropollutants (OMPs) in wastewater treatment and potable reuse.
-
Using ATP And NGS To Monitor Nitrification
China Steel Corporation, a steel producer in Taiwan, produces wastewater that is high in organics, ammonia, solids, and other waste products. The wastewater is treated on-site using a series of biological treatment processes. The variable influent quality can make it challenging to meet treatment objectives.

Topeka WTP Installs Integrity A-758 PLUS™ Lime Slaker System To Replace Existing Lime Slaker
The Topeka Water Treatment Plant (WTP) — a 60 million gallon per day facility - serves Topeka, Kansas and surrounding areas. Built in 1945, the plant underwent several renovations with the most recent upgrading the plant to its current capacity in 1993.
In 2015, plant officials decided to replace the first of the existing slakers and, after considering offers from several slaker suppliers, chose the A-758 PLUS™ paste-type lime slaker manufactured by Integrity Municipal Systems, LLC (IMS). Read the full case study to learn more.

Repair Of Major Damage To High Density Polyethylene Wastewater Pipeline
Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

Magnetic Flow Meters Improve Recycling Of Gas Well-Produced Water
As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

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.
