Z-88® Radium Treatment Process - City Of Bridgeton, New Jersey

This radium removal pilot study was conducted for the City of Bridgeton, New Jersey’s Well No. 19 treatment facility. The Bridgeton water system contains concentrations of radium and gross alpha in excess of the Maximum Contaminant Levels (MCL).

District Heating In France: A V-Cone Customer Success Story

The V-Cone® is widely known for its success as a metering solution in the oil and gas industry, but it’s also a burgeoning solution for many industrial applications, including district steam. The V-Cone’s tolerance for a range of flow conditions and media, as well as available customization, make it a viable, lasting solution for many unique new and retrofit steam applications.

Aeration Blowers In The Wastewater Industry In North America

The economical operation of a wastewater treatment plant depends largely on the design and the interplay of the aeration and process controls. Moreover, the human factor and the management objectives are at the heart of the plant’s reality and should also be taken into consideration. Selection and thoughtful integration of all the subsystems is of paramount importance. By Aerzen

Filamentous Bacteria Controlled: A Quick And Easy Solution

The City of Kalispell used ingenuity, and just a few inexpensive parts, to solve a problem common to biological nutrient removal facilities. By Rebecca J. Bodnar, chemist and industrial pretreatment coordinator, Kalispell Advanced Wastewater Treatment Plant

Dual Auger System Eliminates Clogged Pumps Caused By Flushable Wipes

The Drake Pump Station, located in Saginaw, Michigan experienced chronic pump maintenance due to flushable wipes. Although the dry pit pump station represented only 0.1 million gallons per day (mgd) of flow in the city’s collection network, it required a substantial amount of servicing – up to three times a week. This consisted of two operators spending four hours manually removing rags in a confined space entry to clean out the clogged pump. It was a dirty, unplanned, and time-consuming task.

Enhancing Leak Detection With Remote Pressure Monitoring

Remote pressure monitoring is increasingly being implemented by progressive water utilities, both large and small, to get better visibility into their distribution systems. This results in lower operating costs and reduced stress on their aging pipe networks.

Bio-Organic Flocculant Treatment For Phosphorus Removal: A Zeoturb Case Study

Regulating the discharge of phosphorus from industrial and municipal wastewater treatment plants is a primary factor in averting the eutrophication of surface water sources. Phosphorus is one of the key nutrients that contribute to this process in both lakes and natural waters. Its existence has caused major water quality issues such as the diminished recreational value of these surface waters, increased water treatment costs as well as the potentially lethal consequences of mycotoxins from algal growth.

Which Method Is Suitable For Treatment Of Heavy Metals In Paper Mill Wastewater?

The paper and pulp industry is among the largest industrial users of water resources operating across the world. Typically, pulp and paper industry operations require on average about 54-70 m3 (18,000 gallons) of water per metric ton (2200 pounds) of processed paper goods. This water usage is staggering, and water is used in almost every single part of the pulp and paper manufacturing process. This paper mill wastewater is produced in significant quantities in addition to residual sludge waste from initial pulp digestion to pulp slurry operations and washing the paper-making machinery.

How Engineers Can Help Prevent Catastrophic Flooding

Severe weather events are some of the largest looming threats to civilization in the next many decades. The power of water is humbling, something that anyone who has ever been through a flood knows well. Floods can wreak havoc on urban communities, destroying homes, but also destroy environments, damaging wetlands and natural habitats.

Aerated Biological Nitrogen Removal

Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

Automatic Scraper Strainers Protect Critical Membrane Systems

Automated scraper strainers pre-filter water and wastewater to protect fragile membrane systems from damage caused by large, suspended particles, reducing maintenance and replacement costs.

Process Optimization For Flow Measurement

The Saalfeld-Rudolfstadt Association in Germany must rely on cutting-edge technologies that optimize flow measurement in order to allow for smooth processes and supply 82,000 inhabitants with clean drinking water. 

Dosing Of Sodium Hypochlorite Solution For Drinking Water Disinfection

A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

Protecting Pumps From Dead Head Conditions

The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

Remote Monitoring And Maintenance Through Digitalization

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.

'TOTEX' Is Key When Purchasing Instrumentation

There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

An Ideal Aeration System For Aquaculture Corporations

Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

Waterworks Joints 101

There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

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.
