Tank Cleaning steps for Rust stain removal

TANK CLEANING METHOD Application

Spraying Direction:-
Using an empty/clean 210-litre drum, fill with 190 litres of fresh water and add 20 litres of Metal Clean Bright   This makes a 10% solution, which can be sprayed onto areas in coated tanks where rust stains are showing and over actual rusted areas.  Once spraying is completed, wait 20-30 minutes and fresh water rinses with lots of water if possible use Butterworth machines for a more efficient result.  This method can be used in stainless tanks to “freshen up” the look of the stainless materials.  Make sure to rinse the tank very well, as residual detergent within the Metal Clean Bright will show up in a Wall Wash.
Injection – Not suitable.

Re-circulation:–
When hand spraying is inadequate (too much area to cover), prepare a 2% - 5% solution in the tank using fresh water, heat solution to 50 degree C, then circulate the solution through Butterworth machines for 3 x 45 minutes drops minimum.  When using fixed machine recirculate for a minimum of 3 cycles.  Rinse out the tank using hot seawater 85o C for 2 hours making sure that there is no form remaining in the water at the pump stack drain cock.  After the hot wash, the tank must be rinsed with fresh water and dried.

* If the mixture is allowed to overheat, it will soften epoxy/phenolic coating.
* Use a strainer at the pump stack when circulating any solution.
