During a conversation at Starbucks today, a polite lady announced that she couldn’t help by overhearing my conversation about water filtration, and asked me, “can you really use that to clean water” ? A light bulb went off and I thought this would be a cool idea for a blog post. So here are some water filtration tidbits that you may not have known.
- Bone Char – crushed animal bones that have been incinerated and chemically activated can be used to remove chlorine and heavy metals from water.
- Calcite – also called crushed limestone chips are an economical way to raise the pH of acid solutions. Calcite is often used as an inexpensive way to add calcium to water.
- Polypropylene Hose – can be used to remove oil from water. Oil will actually attach itself to the surface of plastic hose. By the motorized circulation of a long loop of the hose, utilizing a hose scraper and basin to collect the scraped oil, most oily waters can be cleaned up with this crazy technology.
- Crushed Walnut Shells – have been used effectively to remove silt, mud and other large debris out of water. When water passes through a bed of the shells, large particles can be removed. The poultry industry has used walnut shell filtration to remove feathers from plucked chickens.
- Discarded Athletic Shoes – are commonly used to remove toxins from water intended for intravenous solutions. (Okay, this last one is bogus. I just wanted to see if you were paying attention)
