Investigation procedure of biofilter

Biofilters
The problem

A customer of ours, who is active in the paint/coating industry, has a biofilter that doesn’t perform in an optimal way. In order to guarantee an optimal functioning of a biofilter, there are several parameters that must be taken into account, being pH, temperature, humidity. If these parameters are not within certain values, the biofilter will lose a large part of its efficiency. We then investigated why the biofilter was not functioning properly, based on a few samples. Based on a few samples and using analyses, we mapped the "health" of the biofilter. Finally, the observations are also immediately linked to measured emissions, so that we can continue to guarantee a good follow-up and see the effect of the expended efforts.

Our solution

Investigation procedure:

  1. The customer's biofilter covers an area of about 80 square meters. It was therefore important that we took the samples at different locations in the biofilter.
  2. The biobed had a depth of approximately one and a half meters. That is why we also took samples at different depths at every sampling point, to check the condition of the bed.
  3. These samples were then examined in a lab on various levels, being PH, electrical conductivity and the activity of the micro-organisms.
  4. Based on the lab results, we then offered solutions to maximally improve the functioning of the biofilter, solutions that we delivered in the form of a research report.
