Use of percarboxylic acids for scale prevention in treatment systems

A method for reducing scale formation from a target comprising:

• contacting a target with at least about 2 ppm C1-C22 peroxycarboxylic acid composition, wherein the peroxycarboxylic acid does not include sulfoperoxycarboxylic acids, wherein the target is contacted at a pH below about 10.5, and wherein the contacting step is for a sufficient amount of time to reduce scale formation;
• and
• reducing said scale formation.

The method of claim 1010 wherein the water source or the peroxycarboxylic acid composition further comprises a friction reducer, a corrosion inhibitor or a viscosity enhancer.

A method for dissolving and removing scale from a target comprising:

• contacting a target with at least about 2 ppm C1-C22 peroxycarboxylic acid composition, wherein the peroxycarboxylic acid does not include sulfoperoxycarboxylic acids, wherein the target is contacted at a pH below about 10.5, and wherein the contacting step is for a sufficient amount of time to dissolve and remove scale from a target;
• and
• removing said scale, wherein said scale is an iron sulfide, an inorganic calcium component, or an inorganic sulfate.
