Klargester BioDisc Chain Repair – Lanark, South Lanarkshire
Our Klargester BioDisc chain repair service in Lanark, South Lanarkshire ensures your sewage treatment plant runs smoothly, avoiding costly breakdowns and compliance issues. This recent job involved catching a stretched drive chain before it caused a full system failure, saving the customer from potential rotor seizure and motor burnout.
What We Did During the Service
We carried out a full inspection and preventative maintenance to restore the unit’s performance:
- Drive Chain Tensioned: Adjusted slack and verified sprocket engagement to prevent skipping or derailment.
- Alignment Checked: Ensured correct chain run across drive and rotor sprockets to minimise vibration and wear.
- Condition Assessment: Checked for corrosion, stiff links, and elongation – still within service limits.
- Gearbox & Pulley Evaluation: Confirmed bearings were sound and running smoothly.
- Motor Draw Test: Tested under load to ensure no excess strain.
- Rotation Alarm Test: Simulated fault to confirm correct alarm trigger.
- Full System Test: Verified aeration, rotation, and final effluent discharge performance.

By resolving the issue early, we avoided costly downtime and extended the lifespan of critical components. Preventative servicing is always cheaper than emergency repairs.
Common Klargester BioDisc Chain Problems
Across South Lanarkshire, many BioDisc systems we attend show signs of chain wear. Common problems include:
- Drive chain stretching under continuous load
- Misalignment leading to derailment
- Motor overheating from excess resistance
- Rotor stalling due to failed rotation sensors
Neglecting these faults can cause sewage backups, environmental breaches, and failed compliance inspections. More on proper maintenance can be found on the Klargester manufacturer’s website.
