PROJECT HIGHLIGHTS

Commissioned September, 2010 Domestic WW, New C onstruction Permit(s); Reuse NA/NA/0.2    (TN/TP/Turbidity) Housing Development ⇒ Pond, Irrigation MMF Capacity: 0.23 MGD $36.09/gal 2 FTE (Full‐Time Employees)  
Has a small footprint, cost less to maintain, produces water that can be reused without restriction.”

DESCRIPTION

Nestled in a valley between the Pukalani Country Club’s golf course and a surrounding residential community, you will find the Pukalani MBR Water Reuse Facility.    It is a state‐of‐the‐art membrane bioreactor system (MBR) producing R‐1 water that is reused to irrigate an award‐winning golf course.   Tom Johnson, Plant Manager, oversees the entire facility.    The plant was designed to far exceed Hawaii’s R‐1 water reuse limits.  Although there are no nitrogen limits on the island, the MBR is designed to meet a total nitrogen effluent of less than 10 mg/L.    Aside from the great quality effluent, Tom has seen other benefits from his new MBR.    It has improved the efficiency of his belt filter press (producing 17%‐18% cake), dropped his polymer use and hauling cost by 50%
