NUTRIENT MANAGEMENT SOLUTIONS
You know the problem. You remove phosphorus to meet your effluent limits and protect local waterways from nutrient pollution, but now you’ve got a new problem: struvite. You could use chemicals, but they’re expensive and increase sludge production.
THERE IS A BETTER WAY:
OSTARA’S PEARL® AND WASSTRIP® PROCESS
Ostara’s technology suite helps communities around the world manage valuable phosphorus resources while meeting increasingly strict phosphorus limits. Our nutrient recovery system helps save on chemical costs, reduce sludge loads, and create a new revenue stream through the sale of high value recovered fertilizer. Plus, it reduces your carbon footprint – that’s not just good operational practice, that’s good stewardship.
THE PHOSPHORUS CYCLE TODAY
THE OSTARA SOLUTION
By reducing effluent phosphorus levels, Pearl helps to consistently meet nutrient regulations while improving the performance of the entire treatment plant.
WASSTRIP complements the Pearl process by releasing phosphorus upstream before it reaches the anaerobic digester, sending it directly to the Pearl reactor for optimal recovery. By diverting phosphorus from the sludge stream, WASSTRIP all but eradicates digester struvite and maximizes phosphorus available for recovery within the Pearl reactor.
