This question was posed by an ALN reader. We asked Sebastien Dalmagne at ABC Actini to offer information on effluent decontamination.

Budget considerations have become a burning issue both in the public and the private sector. The pharmaceutical industry is no exception to this rule. An increasing number of projects are now aimed at being a retrofit in an existing facility rather than a whole new building construction. With containment laboratories, this raises some questions that need to be answered.

Here we will briefly review what defines a biosafety level (BSL) and study in more detail the comparative requirements of facilities. We’ll take a closer look at effluent decontamination systems (EDS) aimed at decontaminating the water coming out of a laboratory or vaccine production facility and possibly still infected with live germs and thus creating a possible threat for public health.

A biosafety level is the level of the biocontainment precautions required to isolate dangerous biological agents in an enclosed facility. BSL goes from 1 to 4, with 1 being laboratories that handle flu for diagnostics or research, for example, and 4 being laboratories that research highly pathogenic subjects. All agencies use the same system to categorize areas where biological germs are manipulated, based on the following:

  • The organism’s potential danger (could cause disease in healthy humans)
  • The amount of protection existing or not existing (cure or vaccine)
  • The quantity and type of use When retrofitting a BSL3 or BSL4 facility, the question of effluent decontamination is raised.

Thermal Treatment
Thermal decontamination is achieved with a combination time/temperature treatment. This combination is called the lethality rate and can be calculated as follows:

F0 = Time* 10 ^ ((treatment temperature – 121) / 10)

F0 is an exponential function, so by increasing the treatment temperature by a few degrees, the treatment time is significantly reduced. This may be where a continuous system retrofit can be a wise and cost effective investment.

Maximizing Resources
When retrofitting such systems, customers are looking to optimize the following resources:

  • Room
  • Capital investment
  • Steam
  • Water
  • Detergent (CIP)
  • Electricity

Finding the right equipment for a university or a facility is critical and can save big money. Users should evaluate their consumption needs to determine whether they should go with a batch or continuous system.

Last but not least, thermal sustainable EDS systems can be an easy way to win LEED Credits.

When retrofitting a biocontainment facility many parameters have to be considered. As for effluent decontamination systems, here are the essential elements to remember:

  1. Thermal decontamination is reliable and safe.
  2. Choosing the right equipment can save big money.
  3. New EDS are sustainable and affordable.
