Hazlehurst WWTP—Or-Tec Micro Bar Screen
CASE STUDY
Install Date July 2017
Equipment 2.0 mm
Blue Whale
Micro Bar Screen
Avg Flow 2 MGD
Plant Specs
Prior to July 2017, the Hazlehurst WWTP relied on a manual bar rack screen (1.25 inch) for its screening ahead of its packaged
treatment plant. This required them to manually keep the screens clean, and did not provide adequate protection for their
wastewater plant. A large amount of accumulated debris was recently deposited in the aeration basins and presented the City of
Hazlehurst a sizable cleaning bill and debris removal fee, to restore their aeration basins to working order. They asked Cornerstone
H2O to help them with an alternative to their bar screen, and in July 2017 the Or-Tec Blue Whale Micro Bar Screen (2.0 mm) was
installed. The positive results were immediate. In the first two weeks of operation, according to Lead Operator Opie Hall, the
Micro Bar Screen removed an astounding 3,600 lbs of material that would have otherwise been deposited in the aeration basin.
Their operating costs have been reduced downstream as their equipment, such as aerators, have improved their performance as
they are no longer fouled with debris. Now that they are removing such a large amount of screenings, they are currently
evaluating compactors and washers. For roughly 15% of the cost of cleaning and restoring their aeration basin they now have a
superior screening system. The Blue Whale Micro Bar Screen has been an overwhelming success at the Hazlehurst WWTP.
