How to build a biofilter like the one that treats odors generated during the Valoris™ sludge processing?

Step 1: Build the structure of the biofilter

Take a container of 12.5 m² and fix tubes in the ceiling to serve as a water spraying system.

The water spraying system will homogeneously disperse the water on the compost bed.

Step 2: In the container, build the filter:  a wood structure with a fence over it

 The white tube is used to spread stale air under the wood structure

Step 3:  Prepare the media

Take wood chips and organic compost and spread them in 3 layers over the fence of the wood structure

For the existing biofilter in Edmonton, we used material from Clover bar site:
