A recently-refilled pool at a resort had a problem. A big problem.
When they returned flow to their heat exchanger, the water was getting greener by the minute. Something had changed, and they didn’t know what. So they called Orenda specialist Monica Stamper.
“I was in Hawaii at the time, and I got this panicked phone call at 4:00am [local time]: ‘Help!’…It was difficult to diagnose the problem over the phone, but when they told me what their pipes were made of, it all made sense,” remembers Monica.
As it turns out, their pool had 10-foot long runs of new copper pipes on both the influent and effluent sides of their plate heat exchanger. When water flows through copper pipes (and many other metals), traces of the metal can get dissolved into the water. It’s a similar problem to Flint, Michigan’s drinking water crisis–albeit only a fraction of severity.
Metal pipes tend to pollute water until scale is built up within them. In small doses, metals are not a big deal for pool operators or patrons; this amount of metal, however, was.
Most metal control products in the pool industry are phosphate-based, as phosphates promote the growth of scale in the pipes…but not the Orenda product. Orenda’s SC-1000 Scale & Metal Control is non-phosphate based, and can still address the issues that metal pipes bring about.
Clean up: from green to blue water within three hours
“I recommended isolating their heat exchanger, and adding two gallons of Orenda’s SC-1000, and one gallon of CV-600” Monica recalls.
The customer ran their pool for 45 minutes, then noticed green residue on top of their filter bed. So they backwashed the system. When it was all said and done, 4 gallons of SC-1000 and 2 gallons of CV-600 enzymes were put in, plus four backwashes (approximately 2800 gallons).
Their 30,000 gallon pool went from green to blue water within three hours. Clean water means happy customers, and most importantly, happy patrons.
