How RE300 Works


Rare Earths work differently than other traditional metal salts

Depiction of phosphate removal reaction mechanism of RE vs. Fe

  • Precipitate is insoluble REPO4·H2O (Rhabdophane)
  • Forms strong crystalline ionic bonds
  • Preferentially reacts with phosphorus
  • Achieves nearly a 1:1 molar ratio of RE:PO4
  • Forms MOOH and M (OH)3 intermediates to absorb P
  • Phosphate absorbs on the surface of the floc (surface chemistry)
  • Forms M+OOH and M+(OH)3 intermediates to absorb P
  • Phosphate absorbs on the surface of the floc (surface chemistry)







 

The unique mode of RE 300 reactively results in rapid and stable precipitation of phosphorus. RE 300 generates less chemical sludge that other coagulants because less coagulant volume is needed and intermediate hydrates do not form during the reaction with phosphorus.

Extensive wastewater treatment plant trials have proven the following benefits of using RE 300:

  • Achieves < 0.07 ppm-P with no added capital equipment such as tertiary filters.
  • Reduces sludge volume due to unique phosphorus binding mechanism.
  • Improves clarifier solids coagulation.
  • Improves dewatering in filter presses and centrifuges.
  • Eliminates the need for heated storage and pipe tracing due to its -40⁰F freezing point.
  • Enables plants to meet low aluminum permits while also meeting low phosphorus permits.
  • Inhibits struvite deposition.
  • Non-hazardous product; safer to work with than iron and aluminum based products.
  • RE 300 is a rare earth salt solution developed specially for rapid and stable precipitation of phosphorus in municipal and industrial wastewater facilities.
  • The product can be applied in primary, secondary and tertiary treatment, and has successfully removed phosphorus in trickling filters, rotating bed contactors, sequencing batch reactors, clarifiers, and media filters.
  • RE 300 targeted reaction with phosphorus greatly reduces the amount of product needed to achieve the desired final phosphorus level in the plant effluent waste stream. As a result, less chemical sludge is generated in the treatment process.
  • Municipal plants using RE 300 have repeatedly passed whole effluent toxicity testing at 100% effluent concentration.
  • Product is available in bulk tanker trucks and 265-gallon totes containing 1500kg-solution.
