Product Application

Cargo tank and Cargo hold cleaning
AQUATUFF LIQUID  can be used for tank cleaning after animal, vegetable and fish oil, petroleum waxes, and for cargo hold cleaning after soot, coal, pet coke and other bulk materials using the following methods -

•    Direct injection method with tank washing machines: Dosage rate 10-15 lts. per 1000 liters wash water (1-5%).
•    Recirculation method: Use dosage rate of 20-50 liters per 1000 liter wash water.
•    Spot Cleaning: Hand spray neat or prepare a 10-20 % solution. Leave for approx. 30 minutes before rinsing with water. Keep surface wet.

Pre-Wash
Before cleaning tanks with AQUATUFF  is recommended to pre-wash cargo tanks with hot water 50-60 0C.
For Drying oils and semi- drying oils a prewash of the tanks with cold water should be applied.

The efficient operating temperature varies and is depending upon the type of cargo residues which are to be cleaned. In cases like Palm oil residues the optimal solution temperature is between 55-65 0C at the tank cleaning machine nozzle. Higher temperature tends to bake on the residues rather than removing them.
Hydrogenated oils contain stearic acid with melting point of approx. 70 0C. to clean such cargo residues successfully, a temperature between 72-77 0C at the tank cleaning machine nozzle must be used.
