Reducing the costs associated with sludge transportation is an ongoing challenge for water utilities and a key target to reduce both operational costs and carbon footprint. Wastewater sludges typically have a low sludge content and the goal is to increase this content as much as possible within tight cost constraints to minimise the wasteful transportation of water rather than sludge.
Bio-cageTM is the perfect solution. Designed, manufactured and installed by our in-house team, bio-cageTM is easily retrofitted into existing sludge holding tanks. Requiring no power or chemicals and with minimal maintenance requirements, bio-cageTM really does offer a cost effective and viable solution that will deliver significant operational savings for water utilities.
Installed and performance verified on over 50 wastewater sites across the Southern Water region, bio-cageTM generates an average 33% increase in dry solids with an associated reduction in transport costs. The average payback of the technology is between 12 and 24 months and it is effective on a range of sludge makes.
