Model SF40 - Desalination Antiscalant
From Desalination
SF40 is a specially formulated antiscalant product, containing speciality ingredients can effectively increase the solubilities of dissolved salts. Any crystals that form are dispersed so that adherent sales cannot form on heat transfer surfaces in the evaporator. SF40 is a multi-component blend, providing superior protection against calcium carbonate, calcium sulphate, magnesium hydroxide and other inorganic scales.
Characteristic
- Inhibit inorganic deposit formation in multi-stage flash evaporator or multi-effect distillation units.
- Allow reduction or elimination of acid feeding.
- Reduce acid cleaning cycles.
- Increase thermal efficiency.
- Be cost-effective in use.
Typical Applications
The SF40 may be used in multistage flash evaporators or multi-effect distillation units de-pending on product choice. The product is particularly effective in temperatures above 95°C which is normally problematic for magnesium hydroxide scale and also for calcium sulphate scale above
Treatment and Feeding Requirements
For most systems the dosage will be 5-10ppm.
In MSF systems, SF40 should be fed to the feedwater upstream of the heat recovery section and in the feedwater line downstream of the con-denser unit in MED systems.
Environmental Information
SF40 is environmentally safe.
Packaging Information
