Belgard EV
Engineering summary from PDF text extraction for Belgard EV. Verify every value with the OEM datasheet.
Summary
Product identification
- Product Name: Belgard® EV
- Product Type: High performance liquid antiscalant for alkaline scaling control.
- Active Composition: Aqueous solution of a synthetic polymer based on hydrolysed maleic anhydride.
Application
Belgard EV is designed for the control of alkaline scaling (calcium carbonate and magnesium hydroxide) in all types of seawater distillation plants, with particular suitability for multi-stage flash (MSF) plants.
Physical Properties
- Appearance: Clear amber liquid
- Odor: Slight
- Solids content: 47-53% w/w
- Specific gravity: 1.16 to 1.19 at 20/20 °C
- pH: 2 maximum
- Boiling range: 100-102 °C (212-215 °F) at 760 mm Hg
- Freezing point: 0 to -12 °C
- Solubility in water: Miscible
Handling and Materials
Belgard EV is corrosive in its concentrated form due to being an aqueous solution of an organic acid. Corrosion-resistant dosing equipment, such as 316L stainless steel, PVC, or other plastic materials, must be used.
Recommended injection points include:
- Seawater make-up line after de-aeration and decarbonation equipment.
- Recycle brine stream, typically into the discharge of the recycle brine pump, after blowdown.
Usage
- Consult with a BWA Water Additives representative for optimal dosage recommendations.
Packaging
- Drum: 528 lb (240 kg)
