WASTEWATER
Maintaining And Improving Jersey City Water Infrastructure
Jersey City in New Jersey is undergoing a period of development and growth which has seen its population increase by more than 50,000 people in the last 13 years. To cater for this growth, the Jersey City Municipal Utilities Authority is tasked with maintaining its aging water infrastructure and improving its critical water supply to ensure it can meet the needs of its customers both now and into the future.

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.

How To Boost Industrial Plant Capacity By Retrofitting Aeration Tanks
As industries expand, they typically need to increase the capacity of their wastewater treatment facilities. Increasingly stringent regulatory requirements, such as lower nitrogen limits, may also signal the need to boost treatment capacity. Installing additional tanks and larger equipment not only adds capital costs but increases operating costs as well.

MBBR System Implements Nitrogen Reduction Plant Improvements
Hopewell Water Renewal (HWR) is a 50 MGD secondary wastewater treatment plant that treats the wastewater from local industries and domestic sources of the Hopewell, VA area. The plant began operating in 1977 and treats approximately 85% industrial waste. The facility achieves the treatment permit requirements for both BOD and TSS; however, treatment regulations have changed over the years and now require the removal of nutrients. HWR discharges effluent into Gravelly Run, a tributary of the James River and Chesapeake Bay Watershed.

Ion Exchange Resins Reduce Pollution From Refineries
A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

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).

LATEST INSIGHTS ON WASTEWATER
-
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.
-
Emerging state water reuse regulations are driving adoption of ozone and advanced oxidation, requiring flexible, high-performance systems to meet pathogen, trace organic, and DBP control objectives.
-
Ozone system performance hinges on reactor design, not generator size. Efficient mass transfer, hydraulic integrity, and contact time ensure consistent oxidation, reduced energy use, and reliable treatment results.
