Solartron Mobrey's MSL600 system recently was tested as part of an evaluation process conducted by Toronto, Canada's Highland Creek sewage treatment plant managers. After careful analysis of the results, they determined the MSL600 sludge level monitoring system installed on trial at the plant performed without problem even at temperatures as low as -28°C.

Recent implementation of the Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR) has increased potable water sampling and analysis requirements for an additional 11,000 treatment plants serving more than 18 million Americans.
Maintaining the proper concentration of dissolved oxygen in an aeration basin is necessary to keep microorganisms alive for breakdown of the organic waste. When the dissolved oxygen content becomes too high, costly energy is wasted, and expensive aeration equipment endures unneeded wear. A small Midwestern city is a case in point, illustrating the benefits of continuous dissolved oxygen monitoring and control.
Using reclaimed water for non-potable purposes as a means of conserving potable water supplies is the most prevalent method of water reuse in the United States today. One of the significant challenges for water reclamation facilities is to keep up with the demands for safe, compliant chlorine (Cl2) treatment. One utility that is effectively meeting this challenge is Southern California’s Otay Water District.
Well-designed water distribution and cooling systems,
coupled with sound management and operational procedures, are essential to
control Legionella in industrial facilities—and a monitoring program
should not be considered as a replacement. However, most experts even those
ill-disposed towards routine Legionella monitoring, would agree that monitoring
should be considered if enough legionellosis risk factors apply to the system
in question. No management program, regardless of its treatment, maintenance or
monitoring components, can guarantee the absence of future legionellosis, but
prudent operational practices combined with ongoing review of risk factors will
allow facility managers to minimize exposure to Legionella and to its legal consequences.
Water specialists should make Legionella reduction a top priority
This article will present an overview of Legionella bacteria, its ecology and sample collection strategies. A discussion of the pros and cons of Legionella monitoring also is included.

The tragic events of September 11th highlighted America’s vulnerability to terrorism and spurred an unprecedented domestic security response. Water treatment facilities were identified almost immediately as a potential target for further attacks and were urged by the FBI to implement security measures, most of which are still in place.
