Directions for use
The specially selected polymers in NALFLEET™ MultiVap prevent scale formation by salts in the brine and will efficiently prevent build up of deposit on heat transfer surfaces. The solids are held in suspension and removed with the brine outlet.
NALFLEET™ MultiVap will maintain optimum operating efficiency of the plant and hence maximize water production at minimum energy consumption. The intervals between cleaning are significantly increased.
Use Unitor Descalex for acid cleaning to remove old scale prior to treatment with NALFLEET™ MultiVap.
Seawater evaporators have variable tendency to produce foam during operation. Foam formation may vary with operating conditions, i.e. seawater temperature. NALFLEET™ MultiVap is formulated with antifoam to prevent foaming problems and eliminate carry-over. If foaming should still occur, NALFLEET™ Evaporator Defoamer can be added in a premix with water and NALFLEET™ Multivap for additional foam prevention.
Dosing method
NALFLEET™ Multivap should always be dosed on continuous basis. This can be done with a dosing pump or by gravity based dosing unit controlling dosage with a flow meter. NALFLEET™ MultiVap may be diluted in water for easier controlling dosing and flow rate.
Dosage and control
Required dosage may vary slightly depending on type of evaporator in use; however 10-15ml of NALFLEET™ MultiVap per ton of distillate produced is recommended as initial dosage. The dosage recommendation is based on the rated production capacity of the evaporator.
Example: In a 500 ton/day evaporator.
Treatment used = 500 x 15ml = 7,5 l of NALFLEET™ MultiVap per day.
