 Calcareous Deposits
The Electroline descaling process produces deposits of calcium
carbonate CaCO3 and magnesium hydroxide Mg(OH)2.
Both of these by-products of cathodic
protection are non-pollutant films which are fully soluble in
saltwater. The compound CaCO3 is found in nature as
calcite and aragonite, in plant ashes, bones and shells. Mg(OH)2
is a slightly alkaline compound used commercially as a laxative and gastric
antacid. The percentage of deposits absorbed into solution is
negligible (approximately one part per million). We can state with
certainty that a chemist will find virtually no trace of these
inorganic compounds in discharged ballast water.
In time, even the
deposit growth found on the bulkheads will fully dissolve. Keep in
mind that Electroline is basically an accelerated form of corrosion
protection, and corrosion prevention is the equal and opposite
reaction to corrosion, which is a common
everyday occurrence on land and sea. There is nothing unnatural
associated with this process or its by-products.
