THE OSTARA SOLUTION

THE PEARL PROCESS

  • The Pearl process recovers up to 85% of phosphorus and 15% of nitrogen from Stickney’s treatment streams before they accumulate as struvite in the pipes.
  • Ostara’s proprietary technology is based on controlled chemical precipitation in a fluidized bed reactor.
  • Nutrient-rich feed streams are mixed with magnesium chloride and sodium hydroxide and then fed into the Pearl reactor where minute particles or struvite “seeds” begin to form.
  • Like a pearl, nutrients (phosphorus with nitrogen and magnesium) grow in diameter until they reach the desired size- suitable for sale in fertilizer blends for agriculture, turf and horticulture markets.
