- Model PHO - Calcium Phosphate Antiscalant

From

0

Genesys PHO has been developed specifically to prevent calcium phosphate and calcium carbonate scaling in Reverse Osmosis and Nano- Filtration systems. Genesys PHO permits system operation at higher pH and recovery than other antiscalants; thus reducing the amount of feed water, reject water disposal and acid for pH control needed, resulting in significant capital and operational cost savings.

Hydroxyapatite crystal form
  • Suitable for Reverse Osmosis (RO) and Nano-Filtration (NF) membranes
  • Replaces acid addition
  • Compatible with all types of polyamide membranes
  • Allows high recovery rates
  • Simple Test Method
  • Inhibits common scales
    • Calcium carbonate/sulphate
    • Barium/Strontium sulphate
    • Calcium phosphate
    • Silica

  • Genesys PHO should be dosed continuously to the feed water upstream of the cartridge filter.
  • The dose rate of Genesys PHO is dependent on the calcium and phosphate content of the concentrate stream, as well as pH, temperature and ionic strength. Genesys staff will be pleased to provide advice on the most suitable dose rate for a particular water analysis and set of operating conditions. Genesys PHO can be diluted and is fully miscible with water in all proportions.

Genesys PHO is a non-hazardous, synergistic blend of phosphonates and carboxylic acids, compatible with carbon steel and other commonly used materials of construction. A material safety data sheet is available on request.
