10 Reasons To Use UV Water Treatment In Low-Flow Wastewater Facilities

While UV treatment can be used to complement traditional chlorine disinfection, many low-flow wastewater facilities are using it as an alternative to chlorine due to its many benefits.

Stepping Up To Smart Aeration

According to the U.S. EPA, municipal water and wastewater treatment systems account for 30 to 40 percent of the total energy used by municipalities in the United States. In wastewater treatment, the biggest chunk of this energy consumption comes from aeration. Within a typical WWTP, the aeration equipment used to maintain the required dissolved oxygen (DO) levels in the activated sludge process can account for as much as 60 percent of the total plant energy use (Source: EPA.gov). As municipalities and plant operators look for ways to minimize energy use and contain operating costs, aeration is a natural area of focus.

Corrosion In Wastewater Systems: More Than One Bug

The role of various bacteria in the destruction of concrete in wastewater systems has been recognized since 1945. Already susceptible to old age, wastewater infrastructure systems are also threatened by corrosive bacteria — but they needn't be. By Heather Ramsey, John Davis, and Gary Hall

Creating Stability For The Energy Revolution Takes Ability

ABB provides an extensive selection of proven measurement and analytical products and solutions for power generation industry applications.

Rhode Island Wastewater Plants Key To Water Quality Reversal

Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort.

KLa Slot Injector™ Aeration System Assists Cheese And Whey Production Plant Solve Its Nitrogen Discharge Challenge

A gourmet cheese, whey protein, and lactose production facility located in the Midwest had been utilizing a land application system for effluent discharge for over 40 years. Using a combination of ridge and furrow and spray irrigation, the plant had many years of success applying their wastewater to the land.

North American Benchmark Study Comparing CCTV Vs. FELL Inspection On 322 Gravity Sewer Mains

This study presents key findings for a first-of-its-kind 14-mile North American pipeline benchmark study that compared CCTV inspection against FELL inspection results. 

Meet Stringent Phosphorus Limits Under A Wide Range Of Conditions With The CoMag System

The Village of Waterbury Wastewater Treatment Plant (WWTP) is located on the Winooski River floodplain, which poses challenges from significant flooding during the spring runoff and storm seasons to strong algal blooms in late spring.

FLEX-TEND® Flexible Expansion Joints, Features And Specifications

FLEX-TEND® flexible expansion joints are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced or the gradual motion of soil subsidence. This bulletin offers a concise listing and discussion of the important features and materials of the double and single ball assemblies.

Mapping And Identifying The Source Of Water Quality Issues

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

AquaSBR Sequencing Batch Reactor: Food And Beverage Industry

This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

Microbial Control In Cheese Making

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.

Reducing Total Phosphorus In Water Resource Recovery Facilities

Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

Automatic Rinse Tank Controls

Proper rinsing is one of the most important steps in quality manufacturing or metal finishing. Plenty of low cost, good quality water for rinsing has been available in the past, so rinse water conservation has been largely ignored.

Analyzing Total Organic Carbon In Sea Water

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

How To Optimize Your DAF System With Air Dissolving Pumps

Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.
