Sanitization & Biofilm Removal

Astro Pak’s Disinfection, Sanitization & Biofilm removal chemistries and processes are proven to remove both biofilm accumulations and bioburden that is migrating within the system and equipment.

Astro Pak has a wealth of experience and success in resolving the sanitization and disinfection needs of bio-burdened critical systems. Rouge removal and UltraPass® passivation are important services that work in tandem with sanitization to address bioburden growth. Our sanitization chemistries remove oxidation of bioburden cells and eliminate contamination to the level of disinfection or sterilization. Disinfection during pre-commissioning of new systems or after shutdowns can prevent future contamination issues. Astro Pak’s consultants and scientists are experts in providing guidance and data interpretation that ensures long term control for persistent issues.

Astro Pak’s fleet of vehicles, mobile skids, equipment and chemicals allow us come onsite to meet your disinfection and sanitization needs. We also can process tubing, fittings, and other components in our shops located nationwide. Immediate response for emergency outages and critical utilities are routinely provided.
