PROJECT HIGHLIGHTS

Commissioned March, 2006 Industrial WW, Greenfield Permit(s); Not Required 35/3.3/NA   (TN/TP/Turbidity) Pharmaceutical ⇒ Industrial Reuse, Boilers, Cooling Towers, RO Pre‐Treatment MMF Capacity: 0.6 MGD $20.0/gal 1 FTE (Full‐Time Employees) 
The AMGEN MBR system was designed to run at > 18,000 mg/l MLSS and feed RO membranes as part of a zero discharge process.

DESCRIPTION

This Enviroquip MBR System was designed to meet stringent Puerto Rican discharge standards and is an integral part of a "0" discharge process.   Targeting an SDI < 2, MBR permeate is fed to an RO system before being reused onsite.  The plant was designed to run at >18,000 mg/l MLSS in order to accommodate high loading in a small footprint.   Enviroquip TransMax (medium bubble) diffusers supply supplemental oxygen both in the pre‐ aeration and digestion/sludge holding process zones.
