Method and composition for the treatment of blackwater collection systems

A composition concentrate for use in removing and preventing buildup of blackwater deposit in a blackwater collection or treatment system, the composition concentrate comprising:

• in the range of about 10 to about 75 wt. % of acidic solubilizing agent;
• in the range of about 1 to about 40 wt. % of nonionic wetting agent;
• corrosion inhibitor in an amount sufficient to prevent corrosion of the blackwater collection or treatment system by more than about 250 mils per year according to ASTM Test Method #30;
• and
• a solvent/carrier medium.

A method for removing and preventing buildup of blackwater deposit in a blackwater collection or treatment system, the method comprising:

• contacting at least a portion of the blackwater collection system with a blackwater deposit treatment composition, the treatment composition comprising:
• in the range of about 2 to about 15 wt. % of acidic solubilizing agent;
• in the range of about 0.2 to about 8 wt. % of nonionic wetting agent;
• corrosion inhibitor in an amount sufficient to prevent corrosion of the blackwater collection or treatment system by more than about 250 mils per year according to ASTM Test Method #30;
• and
• a solvent/carrier medium;
• and
• removing at least a portion of the treatment composition from the portion of the blackwater collection system.
