The City of Lexington wastewater treatment plant was facing ongoing downstream pump blockages and maintenance headaches caused by aging climber screens and rag bypass. With an average flow of 3 mgd and peak flow of 14 mgd, reliability and efficiency were critical.
To solve these challenges, the city partnered with HUBER Technology to upgrade their screening and screenings handling system. The installation of the HUBER RakeMax in 2021 greatly improved performance, so when the opportunity arose to continue improvements, the city moved forward with an additional RakeMax and the newer RakeMax CF "Center Flow" design.
The addition of the HUBER WAP4L Wash and Press and conveyor system enabled thorough washing and compaction of screenings, resulting in cleaner operations, reduced odors, lower disposal costs, and significantly decreased downstream clogging.
The outcome: A more reliable and efficient headworks process, improved plant operations, and reduced maintenance demands.
- Reduced downstream pumping issues
- Cleaner and more efficient screenings handling
- Lower operating and disposal costs
