Abstract
This disclosure provides techniques for detecting/inhibiting corrosion of in distribution/recirculation service lines and for using tin dioxide as a surfactant to coat at-risk piping surfaces. For example, disclosed techniques can be used to correlate corrosive conditions with fluid type, source and other environmental parameters, and to treat piping so as to insulate corroding areas. A stannous dosing system, and optionally, associated downstream filtration, can be used to efficiently deliver tin throughout piping surfaces at interest, and thereby facility local tin dioxide surfactant buildup to target thicknesses, at difficult to reach locations. In one embodiment, disclosed systems can be used to build a correlation database that can be used in the automated control of systems taught herein.
