Converting Sewage sludge to energy in the waste water industry

Technological innovation is completely changing how the industry deals with sewage sludge and advanced digestion schemes to improve processing efficiency and convert sludge to energy are now commonplace.

Many companies still use bucket loaders for part of the operation, but there is a growing requirement for robust bulk material handling solutions that deal with a material that continues to be challenging.

Indeed, if you already operate thermal hydrolysis and AD production facilities, and you receive material from satellite treatment works or transport processed residues offsite, you’ll already appreciate how important handling, storage and conveying systems can be to optimise site efficiency

What if you could streamline the sewage sludge to energy process?

Overhead storage silos and truck loading systems frequently form part of the solution. However, silo discharge and conveying solutions that can deliver a consistent and precisely metered flow of material to downstream processing facilities are becoming more important. Getting this right is critical to AD and thermal hydrolysis systems. And it requires properly engineered solutions that fully understand the properties of the materials you are dealing with.

The processing solutions are already available…

Continued development of an integrated solution that increases efficiency and streamlines the containment and distribution of waste water has matured over recent years.

Projects like the Southern Water waste water treatment works in Havant and  Southampton [read more here] include raised storage silos, designed to allow de-watered sludge to be directly loaded into trucks below for transportation off site, as part of the company’s thermal hydrolysis and AD programme.

The solution is to incorporate the latest sliding frame technology with screw conveyors and integrated control systems to ensure a consistent discharge of material.

A proven solution with measurable results!

For Anglian Water in Norwich and United Utilities in Wigan similar solutions are in development, incorporating sludge cake silos with sliding frame technology and discharge solutions using sludge pumps and process feed silos for downstream Thermal Hydrolysis. [Read more]

Turning adverse elements into successful material handling

The industry is evolving fast, but one thing remains constant – sewage sludge. It might be non-free-flowing and difficult to handle, but increasingly it’s seen as a valuable resource.

Demand for resilient materials handling solutions is up and choosing the right engineering partner is crucial for site efficiency and optimisation.

With 30 years’ experience and dozens of working solutions, Saxlund has refined the strategic elements required to reduce consumption and assist in converting sewage sludge to energy.

Obviously identifying the areas of improvement that can be achieved in the management of your sewage sludge, and creating a consistent, measurable discharge of material, can clearly demonstrate to all senior stakeholders a solution that reduces overheads and at the same time increases the efficiency of your process.
