How to read an ORP curve on a working lagoon
Oxidation-reduction potential (ORP) tracks the chemistry behind a lagoon odor: a negative curve means sulfide, a rising one means the smell is receding.

Where aeration's electricity actually goes
Aeration is the largest power draw at most plants, and much of it buys oxygen that never dissolves. Transfer efficiency is the physics behind the bill.

Nanobubble science
How small is a nanobubble, and why the size is the point
Under 200 nanometers, a bubble stops behaving like a bubble: no rising, no bursting. The physics of why size changes what oxygen can reach.

The algaecide ledger: an exercise with your own invoices
No prices from us, just a worksheet: total your own treatment invoices by year and watch the direction. The trend is the argument.
