Replacing mechanical seals twice per year was difficult and expensive for Chester, IL, but a more serious problem occurred when the seals failed with the Mississippi River at flood stage and the sealed lift station underwater.

Ephrata Borough Authority WRRF, located in the MidAtlantic region of the United States, has been battling chronic sludge settling issues since undergoing a BNR upgrade in 2011 to meet new permit limits. During the winter months, SVI values have reached as high as 300 mL/g.

The packaged Smith & Loveless TITAN MBR™ Membrane BioReactor (MBR) provides commercial and private developers the most cost-effective solution for enhanced wastewater treatment and water reuse. Enhanced to make operation even more automated and simpler, and regular maintenance even safer and less frequent than any other membrane system, the new TITAN MBR™ features more compact models with the ability to achieve customized effluent goals and water reuse efficiently.

In sewage works of Japan near bay areas, the tightening of restrictions on nitrogen and phosphorus has resulted in greater needs for reconstruction and replacement of infrastructure, to switch from the conventional activated sludge process to the advanced treatment process without newly expanding aeration tanks.

Real-time monitoring with fluorometers and turbidity sensors ensures optimal water quality in aquaculture, enhancing fish health, preventing disease, and promoting sustainable seafood production.​

The technology to produce low pressure air, an energy intensive ingredient in the wastewater process, has made significant steps forward in recent years. Unfortunately, the specifications for testing these new sophisticated air producers have not kept pace.

In this blog, we explore how ozone technology helps reduce pharmaceutical residues in wastewater, ensuring safer water for both the environment and communities.

Originally constructed from the 1920s to 1949, the Gulf Intracoastal Waterway (GIWW) is one of America’s most remarkable transportation arteries. The New Orleans District U.S. Army Corps of Engineers operates and maintains the GIWW in Louisiana, and maintains its six locks for both navigation and agricultural purposes.

V-Bio Polyethylene Encasement is the latest scientific advancement in corrosion control for ductile iron pipe.  Its revolutionary formulation allows for complete confidence on the part of the owner, engineer and municipality that no matter how aggressive the soils, the rugged iron pipe installed will last for generations.  This new technology builds on more than 50 years of research and development by the Ductile Iron Pipe Research Association.  By Jordan Byrd, AMERICAN Ductile Iron Pipe

As water reuse becomes a critical part of water security, municipal water utilities will increasingly be under pressure to incorporate cost-effective reuse schemes in their daily operations. It's time for a new solution. 

Any process plant constantly generates a high volume of status data. Today, this data can be extracted from the plant, stored, analyzed, and prepared to meet operator needs and lower marginal costs.

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.

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

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.

Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

Read about the cloth media filter installations that have been operating in food and beverage wastewater plants for over 25 years.

In the water and wastewater market segment, the LLT100 laser level transmitter provides an efficient way to measure levels of liquids.

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.

Flex-Tend flexible expansion joints have a proven record of providing protection for pipelines subject to subtle or sudden movement. As with all products used in the water and wastewater industry, protection is optimized with the selection of the proper assembly incorporated into a sound design. This paper is intended to provide assistance in both of these areas.

As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.
