ANTISCALANT 9209 RX Seawater Distillation Plants
Antiscalant 9209 RX is specially designed to control the development of scale in seawater distillation plants. It is based on a synergistic blend of phosphonates which are found to be more effective than other polymers at controlling carbonate and sulphate scale formation in sea water distillation units .
PREVENTS IRON FOULING and SILICA ANTISCALANT properties.
- Convenient liquid formulation for automatic dosing using suitable dosing equipment.
- Prevents formation of hard scale in seawater distillation units.
- Performance surpasses other similar products.
- Cost effective concentrate.
- Effective at high temperatures.
The correct dosage rate is dependant upon several parameters, including feed temperature, pH, and chemical analysis and will be specified by your consultant after a detailed survey of your plant. To obtain the best results, Antiscalant 9209 RX should be added continuously using a suitable metering pump.
In general PRACTICE :
Antiscalant 9209 RX should be dosed continuously to the feed water upstream of the cartridge filters. Typical dosage rates are 2 – 4 mg/L.
Antiscalant 9209 RX may also be used in sea water applications where iron is present, recycle of brine is in use or there is no feed water pH reduction by acid dosing.
Typical dose rates are 0.5 – 1.0 mg/L
Antiscalant 9209 RX dose rate in the feed water should be less than 5 mg/L in potable water systems.
Antiscalant 9209 RX can be diluted and is fully miscible with water in all proportions.
Antiscalant 9209 RX is an aqueous solution of neutralised phosphonic acid. It has been approved for use in potable water applications and does not contribute to assimilable organic carbon (AOC), which can act as source of nutrient for micro-organisms.
