Every community produces wastewater. It is not something that we can avoid or change. It is full of bacteria, biomass, and it produces odor. But does it have to stink? Do we have to damage the environment to ensure that our noses are happy? Does choosing…
Water & Wastes Digest and Industrial Water & Wastes Digest awarded their 2019 Top Project winners with crystal awards Monday, Sept. 23, at Maggiano’s Little Italy in Chicago during WEFTEC 2019. Each project was nominated through forms on the…
I rarely use my editorial letter for housekeeping purposes. I feel it is better used to reflect my experiences and musings on industry trends and issues. However, there are so many things that we need to alert you about before the end of the year that I…
Accurate, repeatable air and gas flow measurement under harsh outdoor conditions is essential to successful wastewater treatment operations when used in aeration or digester biogas applications. The challenge for plant engineers when it comes to…
Supervisory control and data acquisition (SCADA) systems are an integral factor for operating any modern water collection, treatment or distribution operation. SCADA systems may consist of a few local controllers and operator interfaces or may be far…
Non-revenue water (NRW) represents a serious problem for the global water industry. In some municipal, governmental or private water systems, up to 40% of potable water produced can be lost before reaching the consumer.  Recent estimates place global…
