Throughout the last half-century the municipal and industrial wastewater treatment industry has depended heavily upon the use of waste lagoons in order to provide relatively clean water that could be returned to the environment. These are often called stabilization lagoons.

The air foil bearing, allowing operation without the need for lubrication and maintenance, provides minimum life-cycle costs for the entire unit. Filtration is the only preventive maintenance which is necessary. The production costs of the complete assembly are very low due to the less expensive bearing technology in comparison to turbo compressors made with magnetic bearing this is a significant benefit in addition to reduced cost of eliminating necessary ancillary components such as bearing controllers, additional electrical filters and uninteruptable power sources.

As outlined in earlier articles, increasing public awareness or even seeking legal action are potential tools to help municipalities gain control of the wipes problem. However, many agencies have seen that these strategies are not completely effective in the long term, and they must also employ new technologies to permanently deal with the wipes epidemic.

Learn how wastewater surveillance can be used to anonymously analyze the spread of disease via testing community sewage. 

With infrastructure being such a hot topic these days, it is only fitting that industrial water treatment professionals take a second look at their own infrastructure. Here are some areas where new pressures from the impacts of climate change, population growth, or government regulations can benefit from improved filtration membrane technology approaches.

In a bold move to modernize its wastewater treatment, Bowling Green, Ohio, installed the state’s first second-generation Autothermal Thermophilic Aerobic Digestion (ATAD) system—ThermAer—in 2004. The upgrade expanded the plant’s capacity from 6 to 10 MGD and replaced an inefficient, odor-prone coarse-bubble aeration system.

Faced with rising operating costs, the Water Pollution Control Department of the Unified Government of Wyandotte County and Kansas City, KS turned to Trojan for a long-overdue upgrade.

Wastewater treatment plants are tasked with removing contaminants from water before it’s safely released back into the environment. With the complexity and volume of wastewater treatment, traditional monitoring methods can be slow and labor-intensive. However, fluorometers are transforming how these plants operate by providing rapid, real-time measurements of water quality.

Murfreesboro, Tennessee, is the fastest growing city in Tennessee, and one of the fastest growing cities in the United States with its population more than doubling since 2000. To manage this growth, the city’s Water and Sewer Board recently embarked on an $8.2 million project to construct the Southwest Regional Force Main.

This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.

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.

This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

Siemens offers to our customers the ability to make both process measurements, and to remotely monitor the activity and health of instrumentation, whether you have a SCADA, PLC or DCS system, or not. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.

Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.

A non-toxic, advanced oxidation (AOP) formula of minerals chelated with oxygen and stabilized in an aqueous water solution. It is a viable option in industries and applications requiring a solution to challenging situations where high level effective sanitization and oxidation is required. Read more to learn how the Genclean advanced oxidation treatment solutions can be used in different applications.

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

Selecting the correct accessories will maximize cleaning while minimizing water use, tank refills, labor, and headaches.

Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
