Drumming Up Chemical Injection Drumming Up Chemical Injection

The operating ranges for chemical injection need to be large because of the variability of flow in many treatment operations. As Bill McDowell, Vice President of Operations with Blue White Industries explains in this Water Talk interview, “You might be down to as low as 5 or 10 milliliters a minute and then one hour later; you might need to pump 15 gallons a minute out of the same pump and through the same sensor.”

A True Lifesaver: Grundfos Provides Key Element For High-Quality Water A True Lifesaver: Grundfos Provides Key Element For High-Quality Water

The facilities run by the University of Iowa Hospitals & Clinics have strict standards for water quality, as staff must protect the very sensitive equipment and patients under their care.

Will Peracetic Acid Replace Chlorine? Will Peracetic Acid Replace Chlorine?

Chlorine has long been a water treatment staple, but it’s not without its complications. As an alternative, some treatment facilities have been turning to peracetic acid (PAA) and enjoying several key advantages.

Treatment Alternatives For PFCs Treatment Alternatives For PFCs

Over the past two years, no groundwater issue has perhaps received as much community focus and attention as polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS, often referred to as perflourinated compounds (PFCs). The U.S. EPA issued a health advisory, limiting the amount of these compounds to 70 parts/trillion which kicked off a nationwide evaluation of local water sources.

ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.

Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
