New equipment boosts efficiency at Southern England wastewater plant

A wastewater treatment plant (WWTP) in southern England is seeing strong results from the installation of a new cutting basket macerator—the Borger OrbitGrinder—now proving its worth in tackling tough grease trap effluent.

Specifically engineered to handle fats, oils, and greases (FOG), the OrbitGrinder features pivoted cutting blades that adjust automatically for even performance. Its innovative star-shaped knife holder and circular cutting basket deliver efficient shredding and homogenization, optimizing the material for downstream processing.

Once macerated by the OrbitGrinder, the energy-rich liquid is transferred to the site’s anaerobic digestion (AD) and biogas plant, where it contributes to renewable energy generation.

Designed for easy integration, the OrbitGrinder fits seamlessly into existing systems—even within the tight spatial constraints of the WWTP. Thanks to its flexible installation options, no modifications to the existing pipework were needed.

Unlike conventional macerators with round perforated disks—which often suffer from uneven wear on cutting edges—the OrbitGrinder offers greater durability and a longer service life. Its unique design, including a specially shaped baffle plate, also ensures even distribution of the pump’s suction force for consistent throughput.

As with all Borger equipment, maintenance is streamlined through its Maintenance-In-Place system. A gas-strut-assisted quick-release cover allows for straightforward servicing—eliminating the need for time-consuming disassembly.

With its reliability, cutting efficiency, and service-friendly design, the OrbitGrinder is fast becoming a standout performer in wastewater treatment technology.
