Excess flow valves (EFVs) and flow monitors are essential to the functionality of many liquid or gas systems. In spite of their importance, these components are often overlooked during a system’s design phase. Often, standard mass-produced EFVs and flow monitors simply don’t perform or fit in-line with expectations.
In the mid-1800s, the world experienced the third Cholera Pandemic. This time, the disease killed more than 23,000 people in Britain alone. No one knew where the disease was coming from and doctors couldn’t stop it.
This blog post discusses ChemTec products for gas delivery systems. It covers excess flow valves, flow monitors and custom solutions from ChemTec.
Sludge sounds unattractive, and indeed usually is. Defined as, “a muddy or slushy mass, deposit, or sediment,” it’s the kind of thick, viscous goo you’ll find at the bottom of a pond. The thought of activating it conjurors up images of some science-fiction blob slithering through your town or city.
That’s actually not too far from reality. While it’s probably not in your neighborhood, activated sludge may well be just outside your city limits. The good news is that it’s far from harmful. In fact it’s positively beneficial as it forms an essential component of many large-scale wastewater treatment systems.
