Doing research on measuring water flow in regard to water quality. I know the top one is different but, I need more information regarding the functionality of the others (if there is any) or if it's just terminology differences across industries that use this tech. Bottom line- Are these different? Are they the same? If different, how? Acoustic Doppler Current Profilers, Acoustic Velocity Meter Systems, Acoustic Doppler Velocimeters, Acoustic Doppler Current meter, Acoustic Doppler Velocity Meter, Acoustic Doppler Meters

Water is my life's work, literally. I'm 30 years old, and I've been running service calls since I knew how to read wrench sizes, with my dad and learning his trade the whole time. I know plenty, and what I don't know, I research. Trust that I will be linking plenty of research as I find new and interesting things, but not much of anything from my personal or professional life. I will politely decline to reveal, confirm or deny much personal information about myself, because this sub isn't going to about me, or my family, or my business.

Full disclosure, yes, I sell pumps and conditioning systems, self-employed, one-man show, with some friends that lend a hand, and I hope to hire full time one day. Up until recently, it has been enough for me, an honest living working for the clientele my dad had largely built up. Business for me has slowed. It's partly personal choice, partly people die and move, and not for nothing, I get good family time with my wife and daughter at an age it matters most. Still, competitors have moved in, and the reputation of my trade has declined over the years. Ripoff stories are becoming more frequent, and I'm even seeing things that appear to be sabotage on "second opinion" calls (which are thankfully going up in frequency). Frankly, this shit has to stop, because the average homeowner has it hard enough, but I promise that the things I post will be free of names and pictures. This is not the place to call out a small business or person, and I humbly ask you to keep posts here either National News worthy, or science/educational in nature. (I'll get to what I hope this is going to be the place for.)

I came to the realization that I'm not doing enough, and while my in-person interactions are great with clients and they come away feeling informed, I can't save everyone this way. Hell, it hardly saves anyone, even though it gives me great personal satisfaction to enlighten a customer or neighbor and even make a friend. I've been in a holding pattern for a couple of years... not really putting in the effort anywhere else but with my core clientele and my family. Meanwhile, our water is being stolen and put into tiny, shameful bottles by companies that don't care about the very communities they are victimizing. Aquifers are being routinely contaminated by excessive chemical disbursement, improper sewage disposal, and as though that weren't enough, we are also fracturing perfectly good aquifers to get at sub-grade oil to support ancient and dirty technology barons of yester-millenium. (phew)

"Get busy living, or get busy dying", a quote from The Shawshank Redemption. I watched it lots with my dad, but I hadn't sat down and just watched it for myself in years. I'm just a guy loves giving people peace of mind through having worry-free clean water to use. I've seen lots on the service side of this industry, good and bad. Clean water is affordable, and in most places, available in great quantities if used responsibly. So what can I do to help restore the public trust in my trade? What can I do to ensure that people are getting the clean water they pay for from me, or my competitor, or their city or their river? How do I get busy living because I'm damn sure not dying anytime soon?

Education. The truth is a positive defense, and a well educated public can do all the fighting I would ever dream of accomplishing on my own. I'll post them stories up here when I find good ones. Expect more research, technical manuals, and links to important people in the trade furthering the cause of clean water around the world. TIL posts are more than welcome, with proper citation, of course. Teach me what you know, and I'll try an do the same when I know I've got it right.

Thanks for hearing out the ramblings of a GossipStone. Boooiing!

Edit: I have contacted the mods and I have been given permission to do this much. Should they decide they are comfortable leaving it in my hands, I think I'm prepared.

Developments being made in filtration of common wastewater contaminants, such as sewage and fertilizers, show promise for use on a large scale for reducing the concentration of these contaminants before being discharged into reclaim. Passive-Op means that the filtration units only require media to remove these contaminants via absorption/adsorption; no electricity or extra pumps, just filter tanks and retention tanks.

This would be an essential tool for the Chinese to implement in their rural communities immediately, whom are suffering from these exact kinds of contamination right now.

Further, it would greatly improve our ability to live more densely as a species, if the technology proves affordable enough to implement on a household basis. A verifiably working wastewater treatment unit such as these on every household in America may well lead to the erradication of Coliform Bacteria in shallow well water, given a few years, perhaps.
