PLANT-BASED WASTEWATER TREATMENT

The CLEARAS plant-based approach recovers valuable nutrients from municipal and industrial wastewater to deliver water quality that meets or exceeds current and future regulations.

 

Our system displaces expensive chemical systems that produce a harmful chemical sludge byproduct.

WHY NUTRIENT RECOVERY

Water quality and availability is a global challenge.  Wastewater treatment operators have two options for removing excess nutrients before they discharge into a public waterway:

 

Chemical Addition

The chemical addition solution binds chemicals to the nutrients, making them large enough to screen out.  The resulting chemical sludges are disposed of in our landfills indefinitely.
