Recover Nutrients While Saving on Operations and Chemicals

Recovered Nutrients Distributed as Crystal Green Pearl Fertilizer


Nutrient pollution can harm waterways, creating algae blooms that upset the natural environment. Ostara helps maintain nutrient levels to sustain a healthy water supply.

Using our sustainable solutions to remove nutrients, you can also reduce energy use, chemical demand, and waste sludge volumes for additional environmental benefits.

When you invest in our nutrient recovery solution, capital costs are recouped in 5-10 years through savings in chemicals, sludge disposal, and maintenance while also creating revenue from Crystal Green Pearl® fertilizer sales





Traditional ways of managing phosphorus to meet effluent limits and protect local waterways creates a new problem: struvite. Instead of solving this problem with expensive chemicals, Ostara has a better way.
