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

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.

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.
