Spun out of research from the University of California, Irvine, Neptune Diagnostics provides services for wastewater treatment plants based on a proprietary DNA diagnostic technology. This technology allows for proactive decision-making to prevent bacteria-related problems at wastewater treatment plans. The company's technology prevents foaming and bulking, which disrupts the separation of solids from water and is primarily caused by overgrowth of filamentous bacteria. Neptune provides an alternative to environmentally harmful chlorination approaches to reducing foaming and bulking.
