microbial growth in PVC pipes

Polyvinyl Chloride (PVC) pipes offer a range of advantages, such as corrosion resistance, cost-effectiveness, lightweight nature, durability, smooth surface, chemical resilience, and insulation properties. These qualities make them a popular choice in various industries such as transport, healthcare and construction. However, PVC pipes are vulnerable to bacterial and mould growth, which can compromise their integrity over time causing odour, staining, and material degradation [1].

To prevent this, manufacturers add BioCote® antimicrobial additives during production to strengthen PVC pipes with built-in permanent defence against microbial colonisation and material degradation.

Most common causes of microbial growth in PVC pipes

Identifying the presence of mould, yeast, and bacteria within PVC pipes can prove to be a challenging task. Several factors can influence microbial growth in PVC pipes:

  • Low water flow and pressure: Breaks or leaks in the pipes can lead to decreased water pressure, which creates conditions conducive to water stagnation in plumbing systems, providing an optimal environment for microbes to thrive.
  • Temperature Fluctuations: Temperature fluctuations affect the balance and diversity of microorganisms in the PVC pipes, which could lead to bacteria and mould growth.
  • Inadequate maintenance: Neglected or poorly maintained plumbing systems are more likely to develop stagnant water issues. Lack of maintenance practices creates favourable conditions for bacteria and mould to thrive and multiply.
  • Organic Build Up: The organic matter accumulation within pipes, comprising substances like hair and food waste, serves as a nutrient reservoir and an optimal environment for microbial proliferation.
  • Inappropriate Disinfection Practices: Improper use of type and concentrations of disinfectants and chemical additives can lead to microbial growth in the pipes.

How does microbial growth affect PVP Pipes?

It is important to ensure that microbial growth within pipes is properly managed, as failure to do so could potentially result in a variety of issues:

  • Unpleasant taste and odour: The presence of bacteria and mould in the piping system can lead to bad odour and taste.
  • Microbial-influenced corrosion: Microbial growth in the piping system triggers corrosion and oxidation damage to PVC pipes leading to stress cracks, leaks, and brittleness.
  • Reduced material life: Over time, microbes start to degrade the materials they colonise, ultimately compromising the integrity of the plumbing system and reducing the lifespan of the PVC pipes.
  • Costly reparations: Significant economic losses due to the need for repairs and replacements.

BioCote® Innovative Solution

Addressing the challenge of microbial growth in PVC pipes requires a thoughtful and effective solution. BioCote® offers an innovative approach with antimicrobial additives that integrate seamlessly into PVC pipe manufacturing. These additives protect against bacterial, yeast, and mould proliferation, creating a cleaner and more hygienic plumbing system.

Unlike surface treatments that may wash off or degrade over time, BioCote® additives become integral to the PVC material, ensuring continuous defence against microbial growth throughout the pipe’s lifespan. This approach not only enhances the pipes’ resistance to odour formation, staining, and material degradation but also extends their lifespan, reduces maintenance costs, minimises risks of microbial-induced corrosion, and enhances the overall performance of PVC piping systems [4].

By taking a proactive approach to microbial control, BioCote® sets a new standard for quality, reliability, and longevity in plumbing infrastructure, providing an effective solution for the challenges associated with microbial growth in PVC pipes.
