Warden Biomedia is excited to announce the release of our newest filter media – Biopebble.
It’s our latest generation, sustainable filter media optimised for efficient biological wastewater treatment for land-based aquaculture facilities and recirculating aquaculture systems (RAS).
Designed for sustainability
The new spherical design improves media mobility, which reduces the aeration energy requirements allowing for more efficient wastewater treatment.
The media is made from 100% recycled material (with virgin options available also) and is fully recyclable at end of life.
Research & development at Cranfield University
The new media design and geometry is based on a 3-year research partnership with Cranfield University. Cranfield have a global reputation for its research in the science, engineering and management of water, and has driven innovation in the water sector for over 40 years.
The research was part of a Knowledge Transfer Partnership (KTP) programme, partially funded by Innovate UK. The partnership between Cranfield University and Warden allowed for the development of a novel media.
Here we demonstrated that a spherical media shape was far superior to standard industrial tubular-shaped biocarriers (TSBs), which need high levels of energy input to aerate the system. The new spherical media reduced the energy input required in the effluent treatment system, since the media require less energy to be agitated in solution.
