America's national pastime may seem a gentle pursuit, but it is not without its fatal hazards. The 2008 book Death at the Ballpark: A Comprehensive Study of Game-Related Fatalities, 1862–2007 catalogs deaths that have occurred while people were playing, watching, or officiating at baseball games. Among the causes is commotio cordis, a concussion of the heart that leads to ventrical fibrillation when the chest is struck during a critical 10- to 30-millisecond moment between heartbeats. About 50 percent of all victims are athletes (and the vast majority of these are male) engaging in sports that also include ice hockey and lacrosse, the U.S. National Commotio Cordis Registry reports.
The water from this unit is pretty much tasteless to me, which is ideal since tap water tastes awful. I grew up with Culligan, which has a certain taste to me, versus this which is just pure. Haven't tested it but plan to. We also added a line to the fridge ice maker so our ice is purified. It was easy to install in our home, and we've used it three months with no issues. The cables are long. today when our sink clogged and we had to drain it, got a mess over all the filters, and they water tubes were all long enough to put the whole unit (still assembled and attached), into the sink to rinse it off. I'm glad it's made in the USA so I know all the parts have stringent manufacturing guidelines. The only thing I would change, is ordering directly from apec instead ... full review
The addition of inorganic coagulants such as aluminum sulfate (or alum) or iron (III) salts such as iron(III) chloride cause several simultaneous chemical and physical interactions on and among the particles. Within seconds, negative charges on the particles are neutralized by inorganic coagulants. Also within seconds, metal hydroxide precipitates of the iron and aluminium ions begin to form. These precipitates combine into larger particles under natural processes such as Brownian motion and through induced mixing which is sometimes referred to as flocculation. Amorphous metal hydroxides are known as "floc". Large, amorphous aluminum and iron (III) hydroxides adsorb and enmesh particles in suspension and facilitate the removal of particles by subsequent processes of sedimentation and filtration.[6]:8.2–8.3
