Cutting Grease With Ongoing Monitoring and Maintenance

Grease is clogging sewers nationwide, creating a costly mess to clean up and a dilemma for officials and regulators. Recently, the Wall Street Journal reported that 75 percent of the sewer systems in the United States work at only half capacity because of grease clogs. The cost of keeping sewers open, a cost borne by taxpayers at a local level, is $25 billion per year. The increase in grease in sewer lines is a direct result of the phenomenal growth in dual-income households who choose to eat out or take-out rather than cook at home.

Metering Pump Technology

Since the introduction of the metering pump, chemical feed for disinfection has been a primary application. As we move into the 21st Century, it again is time to review how we introduce chemicals such as sodium hypochlorite into our water systems. While the goal remains the same, changes in pump technology have been created to provide more accurate and consistent results. This article will discuss current metering pump technologies, proper pump sizing, installation and future enhancements.

Legionella Management and Monitoring: Part 2

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.

Threat of Water Supply Bioterrorism: Who Will It Impact?

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.
