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 CASE STUDIES AND WHITEPAPERS
-
Church Road Transfer Station - Modular MBR Wastewater Treatment Plant
The Church Road Transfer Station (CRTS) is located southwest of downtown Parksville, British Columbia in the Regional District of Nanaimo (RDN). The facility receives organic waste, solid waste, recyclables, and construction/demolition waste from the general public and commercial haulers. Its expansion under the RDN’s Green Building Policy transformed it into a zero-waste facility.

Efficacy Of Electrocoagulation Technology On Selenium-Contaminated Mine Effluent
This paper helps to understand the efficacy of BakerCorp Electrocoagulation (EC) technology and treatment process in treating selenium-contaminated mine effluent. Two mine effluent samples were treated by Baker EC. Selenium constituent concentrations in both water samples were reduced significantly to below reporting qualification limits. Based on the results of the effluent samples, electrocoagulation is an effective treatment option for waste streams found to contain selenium.

Union Township, NJ Automates Pump Station With TASKMASTER®
Union Township, New Jersey was having a lot of trouble with their pump station. Although a small pump station, it was extremely cumbersome to maintain. The station was using a trash basket with a ladder and rail system to screen solids. This was extremely time-consuming, used an excess of manpower and proved to be ineffective at times. They knew they needed a better solution.

Methanol Dosing Technology Helps Denitrification System Pass Rigorous Performance Test
In 2007, Greenville, SC-based Western Carolina Regional Sewer Authority (WCRSA) conducted a rigorous performance test on a new tertiary treatment technology to assess its ability to effectively remove nitrate-nitrogen (NO3-N) without using excess amounts of methanol at its Lower Reedy Wastewater Treatment Plant (WWTP).

Two AquaDisk Cloth Media Filters Replace Six Granular Media Units, Boosting Capacity 540% And Cutting Backwash Volume By 97%
The Portland, Indiana, Wastewater Treatment Plant (WWTP) had been using six granular-media filter units for tertiary treatment since the 1980s. The plant’s treatment protocol includes fine screens for grit removal, followed by primary clarifiers, trickling filters, aeration basins, secondary clarifiers, the tertiary treatment system, and then chlorine disinfection.

Overcoming Obstacles To Increase Wastewater Capacity
It’s a scenario that is becoming more common at food and beverage facilities. The introduction of a new product to market, or a boom in sales of an existing product, prompts management to increase production capacity. While there is plenty of space for production equipment, the corresponding need for additional wastewater treatment capacity may not be readily accommodated.

Sturbridge POTW: Greater Capacity For High Flow Events, Enhanced Clarification For New Regulations
Sturbridge, Massachusetts historically suffered from periodic blooms of filamentous bacteria that caused bulking in the secondary clarifiers of their three activated sludge package plants.

CAGI Data Sheets: Blower Performance Comparison Technical White Paper
Comparing blower performances across different manufacturers and technologies has long been a difficult task. For many years, it was all too easy to present data that, although accurate, was potentially misleading. Manufacturers were selective about what information they published as well as what conditions they chose to specify performance. The result was a numbers game the buyer frequently lost. Fortunately, the Compressed Air and Gas Institute (CAGI), in cooperation with its members, has developed a tool for a fair comparison between blowers.

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.
