PROJECT HIGHLIGHTS

Commissioned December, 2008 Commercial WW, MBR Retrofit Permit(s); Reuse 10/0.2 /5    (TN/TP/Turbidity) Commercial Building ⇒ Toilet Flushing, Animal Ponds, Floor Washing, Irrigation MMF Capacity: 0.0016 MGD 0.25 FTE (Full‐time Employees)  
The Ovivo system cut energy cost by 44% (vs. previous system). Earth Rangers is extremely satisfied with the plant’s operation.

DESCRIPTION

Earth Rangers is a charitable organization for children was founded in 1999. Their headquarters has been designed with the goal of achieving net zero energy.   With this goal, an energy audit was completed that indicated a large portion of their energy resulted from operation of their previous Hollow Fibre waste water treatment plant.   Additionally, they found this Hollow Fibre plant to be unreliable.    In 2008 we were approached to reduce the energy costs of the plant.  We installed state‐of‐the‐art Flat Plate membrane modules, and in turn reduced the air requirements (and energy) of the plant.
