Operating costs in sludge storage and handling are driven by discharge reliability, minimal maintenance effort, and reduced operator involvement. Conventional sludge silos can struggle with sludge bridging, limited access for inspection, and material build‑up around the silo walls—often resulting in downtime, manual intervention, and increased operating costs.
SPIRAC sliding-frame sludge silos are designed to overcome these challenges and deliver measurable OPEX savings. The sliding frame allows the silo to be fully emptied, providing clear and safe access to the silo. This enables silo inspections, cleaning, and maintenance to be carried out quickly and safely if necessary. All hydraulic components for the sliding frame are mounted externally, making routine servicing straightforward and easily accessible. Importantly, the sliding frame itself is maintenance‑free and designed for the full service life of the silo.
Key OPEX benefits include:
- Maintenance‑free sliding frame with lifetime warranty
- External hydraulics for safe and simple maintenance
- Reliable sludge discharge with reduced bridging and blockages
- Reduced manual intervention and labour requirements
- Improved long‑term cost predictability
For wastewater treatment plants looking to improve sludge handling reliability while keeping operating costs under control, SPIRAC sliding frame sludge silos provide a practical, proven, and low‑maintenance solution.

A sliding frame outloading system is an advanced extraction mechanism designed to discharge non-free flowing materials from a flat bottom silo or receival bunker. These materials tend to form a bridge, obstructing the discharge at the silo floor. To overcome this challenge, the hydraulically driven sliding frame comes into action.

Great work from one of our service teams in the UK. The old screen compactor was removed and replaced by a new SPIROWASH® (compactor). It took the service team two days to complete the task and have the site up and running.
