Peroxide. Mother Natures Hamburger Helper

As water treatment professionals we sometimes stumble upon jobs that are very troublesome. Those jobs almost always involve iron removal from ground water with oxidation. Oxidation is a tricky science. Your pH must be near neutral, but never above 8.2. High pH will cause the iron to create sludge. If you are using conventional air injection via venturi, pump or vacuum, you run the possibility of creating iron precipitate sludge. Also, barometric pressure, water temperature, and elevation greatly effect water's ability to hold oxygen.

Peroxide to the Rescue:
Now back to that pesky job leaking 0.5 ppm iron past your air fed iron filter where you've tried "everything". Peroxide to the rescue! What you are lacking is a good wallop of pure O2. 7% peroxide contains 70,000 ppm of oxygen. That will jump start your oxidation! Try it! You will be amazed. Your filter starts working and will nail that last bit of sneaky iron or sulfur . Peroxide works wonders for sulfur too.

For the wholesale market, we have built a complete package to treat water with iron and/or sulfur problems. It is called the Ultimate Oxidizer.

Extra Details you Need to Know:
Now I can continue on with a real snoozer of a post with all the minute details of "peroxification", but there are important peroxide application rules of the road.

  • Use 7% peroxide NSF rated with proper labeling. Any concentration greater than 7% will subject you to the scrutiny of regulators and lawyers.

  • Inject peroxide into the plumbing with a peristaltic pump, like Stenner or Chemtech XP.

  • Never dilute peroxide unless you use distilled, reverse osmosis, or deionized water. 7% peroxide should never need to be diluted, just adjust your pump's feed rate.

  • Store peroxide like a fine red wine: cool and dark.

  • A little peroxide goes a long way. Feed peroxide @ around 2 ppm per ppm of iron or sulfur. Feed into an in line mixer. a.k.a. static mixer, to gain optimal peroxide/water blending. No need for big blending tanks, peroxide works fast.

  • If the finished water turns white with micro bubbles you need to back down your feed pump. "if bubbles abound, turn your pump down". Peroxide is pure. It's just oxygen and water. No mystery ingredients like bleach. Plus with bleach, you run the risk of creating chlorinated by-products. This won't happen with peroxide. Dare I say peroxide is the "green oxidizer". Yup I dare.
