Scale/Schmoo in Water Injection Line

[bpownall]

I have previously posted about a intern project I am working on to determine the best recipie to clean our main water injection lines which have been restricted over the years. A chemical analysis on the stuff shows that it is:

Hydrocarbons: 10%
Soluble salts: 1.40%
Calcium carbonates: .84%
Iron compounds 65.08%
Acid insolubles: 22.91%

Iron compounds were iron sulfide and iron oxide. I am getting a second test done to confirm the findings.

What are some options to clean this line? I would appreciate a variety of chemical options/procedures that I can test by flushing.

Thank you for your help, I do not have much experience yet and am a first year engineer.
