Treating a Treater's Chemical Dependency

Posted February 18, 2014 1:00 PM by Engineering360 eNewsletter

When a Washington state wastewater treatment plant replaced traditional tube-element peristaltic pumps with a new metering pump, its chemical costs dropped by 15-20%. As explained by the plant's operations manager, the pump's "barrel bar feature" triggers an alarm when a 250-gal. tote gets low - no waste from premature tote changes, and no fear of running dry.

Treating a Treater's Chemical Dependency seems to be a duplicate blog.

Is this chemically induced?

"Contact blog admin" didn't work for me.

I'm not sure how that happened, but the duplicate post has been removed.

McCalib explained that Lakehaven installed the metering pumps in the Lakota location because the plant had problems pumping from a tote. Operators could not shut off the pumps mid-process, which made knowing when to change the tote difficult. Occasionally, totes would drain completely. At other times, an operator would change a tote that was 20 percent full. McCalib credits the metering pump barrel bar feature with a 15 to 20 percent reduction in chemical costs, giving operators the ability to meter properly without wasting chemicals or running dry.
It appears that the waste was more an operator issue than a pump issue. Even the most accurate pump will be wasteful if the operator is discarding any usable chemical. 20% full? Really? Poor supervision? Lack of care? Fiscal oversight?
We would take our excess chemical and transfer it to another tote of the same chemical or we would have 2 totes set up so we could drain one completely and then swap over to the other tote.
