BIOFILMS, DEAD LEGS, AND MICROBIOLOGICAL TESTING

BIOFILMS, DEAD LEGS, AND MICROBIOLOGICAL TESTING

"Where there is water, there is life." This saying holds true within our industrial water systems as well. Unwanted microbiological activity can cause corrosion, loss of heat transfer, blockages, and pose a risk to public health. The resources below should be helpful in understanding this complex topic.

THE BASICS

A good place to start is with the "what" and "why."
