Definitions
- Polyphosphates are not as efficient as chromates and they are unstable in a cooling water environment, decomposing by hydrolysis to ortho and pyrophosphates, often causing sludge and deposits.
- Orthophosphates are not as efficient as chromates and if they are not controlled properly they can also form sludge and deposits.
- organophosphonates provide some corrosion protection, they are not nearly as efficient as chromates.
- Organic phosphonocarboxylic acids or phosphinocarboxylic acids have been disclosed as useful to prevent calcium and other scale deposits and to prevent corrosion of iron in circulating water systems. Such compounds are disclosed in U.S. patents 3,933,427, 4,042,324 and 4,159,946.

- the pH of the water was adjusted to pH 8.0 by addition of caustic (50%) and was automatically maintained at 8.0 by a controller which feeds HCl (1% aq. solution) to the tank in response to an increase in pH.

- Manganese as MnCl2 ⁇ 4H2O was added to one of these tanks to a concentration of 7.5 ppm Mn.
- the pH of each tank was controlled at 8.0, using dilute HCl.
- Carbon steel electrodes (1018) which were cleaned with 1:1 HCl and sanded with 320 grade sandpaper to remove all surface oxides were attached to the electrode corrosion probes and immersed in the tanks.
- the instantaneous corrosion rates were monitored using a potentiostatic corrosion rate instrument.
- the experiments were conducted for a period of five days, at which time, the concentration of salts in the baths were approximately four times those of the feed water. At the end of this time, the final average corrosion rates were found to be 1.0 mpy (0.025 mm/y) (mils per year) in the tank with manganese and 2.5 mpy (0.061 mm/y) in
