& Biofilm removal

On-Site Sanitization & Biofilm Removal Services

Astro Pak has a wealth of experience and success supporting our customers with their bioburden challenges. Our biocleaning and sanitization chemistries and processes are custom tailored to address your specific system, equipment and species of bacteria detected.

Biofilms can form in a matter of minutes and do not take much time to spread and mature. Well established colonies develop chemical resistance and become increasingly difficult to eradicate. In these instances, Astro Pak implements a multi stage strategy to “strip” away layers of the biofilm. Moreover, our filtration capabilities are at micron levels and we employ variable output pumps to optimize flow rates for contact time and turbulence to disengage and break up biofilms.

Biofilm LifeCycle

Since bacteria is more apt to attach to a roughened or rouged / rusted surface we often prescribe derouge, electropolishing and passivation solutions to work in tandem with sanitization to mitigate bioburden recurrence. Astro Pak’s Engineering and Technical Services Group includes biochemists, engineers, metallurgists, and surface finish experts to provide guidance in the monitoring and analysis of microbial trend data to ensure long term management for persistent issues. Our integrated approach includes design consultation where we can help you engineer a piping system that facilitates maintenance processes, proper flow rates and minimize water stagnation, a leading cause of bacterial initiation and regrowth.

Microbial Trend Analysis


Reintroduction of bacteria due to a defect in the process or equipment.

Regrowth biocleaning

Regrowth of bacteria due to ineffective treatment.


Frequently Asked Questions

No single chemical is effective in completely reducing or eliminating mature biofilms. Remediation treatments require specialty chemical blends tailored to the wetted materials and bacterial species which have been identified.

A formation of biofilm on the surface of stainless steel can result in differential aeration cells and oxygen depletion under a biofilm which can promote pitting corrosion on stainless steel surfaces.

As the bacteria profile in the biofilm becomes more diversified, the biofilm inhabitants can become more resistant to chemicals.

RO membranes, DI resins, storage tanks, filters and piping systems all provide surfaces that are suitable for bacterial growth and attachment.

Testing of water samples will only return results for the free floating bacteria. Instead, ongoing monitoring of plate-based cultures is critical to detecting the presence of a biofilm while also providing data regarding the timeframe for build-up to occur.
