Description

BIOFILM CLEANING

Biofilms are complex communities of microorganisms capable of colonizing and adhering to almost any type of surface, forming biofilms. In reality, these are three-dimensional structures where the microorganisms are enveloped by a matrix made up of extracellular polymeric substances (EPS) and water. This makes it easier for cells inside to protect themselves from environmental stress and interact with each other, enabling their proliferation.
The threat of these microbiological structures is twofold. On the one hand, because they cause the deterioration of products or surfaces in which they are developed. On the other hand, when biofilms are formed by microorganisms of a pathogenic nature, they are a cause of great concern in the food, pharmaceutical, cosmetic or clinical industries, since they represent a source of contamination of the products and a risk to public health.
The main problems caused by the presence of biofilms are:
• Contamination of the product, loss of quality and its useful life.
• Infections or diseases when pathogenic microorganisms are present.
• Sealing of pipes and pipes, reducing the flow rate and increasing energy costs.
• Obturation and deterioration of membranes, producing the reduction of permeability.
• Reduction of energy transfer and energy efficiency.
• Corrosion of metal surfaces, when sulfate-reducing or acid-producing bacteria grow on the biofilm.
At Aujor we are specialists in performing biofilm cleaning-disinfection. We can carry out the treatment in our facilities or we move to carry out the work on site at the client’s home.
