Our customer continued to fail cleaning validation due to excessive bioburden readings and visual failures. We investigated and determined the root cause: poor piping design, low cleaning velocities, and dead-legs in the system.
Several options were presented for review; ultimately, the agreed-upon method was designed and implemented. Post commissioning, cleaning validation passed the first time successfully.
We were contracted to perform a facility audit, followed by a conceptual and detailed design of a project to resolve the issues and commissioning of the installed project.
