Saxlund Technology Turns Sewage Sludge to Energy
BioEnergy and bulk materials handling company Saxlund International, part of the Opcon energy and environmental group, has secured contracts from Barhale Trant Utilities to design and supply sludge cake truck loading silos for Southern Water waste water treatment works in the UK.
The projects, at Budds Farm in Havant and Millbrook near Southampton, include the construction of raised storage silos, each with a capacity of 240m3 and specially designed to allow de-watered sludge to be directly loaded into trucks below for transportation off site, as part of Southern Water’s thermal hydrolysis and anaerobic digestion program.
The flat-bottomed silos will incorporate Saxlund’s sliding frame technology to ensure consistent discharge of material as well as screw conveyors and integrated control systems. Installation for both sites is due to commence in April with commissioning completed during June.
Saxlund completed a series of water industry projects for Anglian Water in 2014 and is currently building a 454m3 sludge cake process feed silo for KMI Plus on behalf of United Utilities, to supply an on-site Thermal Hydrolysis system at Leigh Wastewater Treatment Works.
New technologies using passive aeration and process control dramatically improve wastewater treatment, according to a Lux Research report published last month.
