Step n°1 : Disperse hydrocarbon molecules
The first step is to drain the water tank. Then fill it with water and add the concentrated hydrocarbon dispersant D.05/11 (ref. 071L) The quantity advised is 5 litres. for a tank of 100 litres of water. Let act the product for about 1 to 2 hours. D.05/11 will micronize the diesel-oil. Drain thoroughly the tank and rinse twice with fresh water.
Step n°2 : Decontaminate the water tank
Fill again water and add BACTI-TANK (ref. 021L) at a rate of 200 ml for 100 litres of water. Drain again while circulating water with all the taps open.
Step n°3 : Return to service the water tank
Fill for the last time the tank by adding BACTI-TANK by respecting normal proportion (either 1 dose of 25 ml for 100 litres od water).
