PROJECT HIGHLIGHTS

Commissioned March, 2011 Commercial WW, Greenfield Permit(s); Discharge 10/NA/10   (TN/TP/Turbidity) Shopping Mall, Commercial Buildings ⇒ Leach Field MMF Capacity: 0.01 MGD 0.5 FTE (Full‐Time Employees)

DESCRIPTION

Big Box stores wastewater characteristics are high loading with wastewater generated from general retail, general supermarket with bakery, deli and meat departments, automotive, food service, garden center, vision and janitorial. The treatment selection would be a simple if the wastewater stayed consistent. However, in a commercial environment such as this, real world application experience tells us that the unpredictable timing of constituents of the feed sources, coupled flow variations, creates an ever changing influent source. Meeting real world application criteria requires systems to be flexible enough to handle or easily recover from the outlier influent constituents, makes MBR the best available technology choice for this application.
