Biofilm Biofiltration Media

Biofilm Biofilter bark media

Existing Biofilters

Over the years we've helped many New Zealand councils and contractors minimise odour complains through the auditing of current bark media and providing a specialised solution.

Often the biofilters get neglected due to the barriers and unknowns for testing the media.

Our technical media team make this process easy by collaborating with council staff, contractors and all other parties that are involved.

New Works and Projects Involving Biofilters

Out technical team actively keep informed during the consultation and design process to make sure the right media goes into the biofilter bed.

Often the design documents stipulate a large bark nugget because it's the most widely available although this isn't always the best product for long term performance leaving toxic odour going into the atmosphere.

Biofilm is an all-natural and resourceful bark based recipe solution specialised to your biofilter needs.

Biofilm was developed to provide a product which was consistent with specifications at time of design whilst still being widely available throughout New Zealand.
