TECHNOLOGY

PEARL®

The core of Ostara’s solution is the Pearl. A fully customizable and modular treatment solution, Pearl fits into your main or side-stream operations removing phosphorus from your treatment system by adding magnesium in a controlled pH setting. This allows nutrients to crystallize into highly pure fertilizer granules, which are harvested, dried and bagged – ready for distribution and sale as Crystal Green®. 

WASSTRIP®

WASSTRIP (Waste Activated Sludge Stripping to Remove Internal Phosphorus) is a value-add to Pearl providing critical benefits to facilities that use anaerobic digestion. Releasing phosphorus upstream before it reaches the digester, WASSTRIP turbo-charges nutrient removal and recovery. Plus, the process protects digesters and equipment from struvite, improves dewaterability, and reduces biosolids.
