Hanit®, The new raised flooring system for Biofilters by Hahn Plastic Ltd.

hanit flooring4   The floor of a biofilter has to meet some stringent requirements. It should provide an excellent drainage  with a stream of air with a very high humidity. In addition, the floor has to be loaded with a heavy biofilter medium and it should not be allowed to warp, bend or collapse.  The UK company Hahn Plastic Ltd. has developed Hanit®, a new set of plastic grills and legs made of recycled material that is able to stand a biofilter media in extremely harsh conditions.

   The traditional option when designing a biofilter floor is using a pre-cast concrete grill. This is often a very convenient way of flooring a a biofilter. The pre-cast concrete structures are resistant, durable under normal conditions and can be easily dismantled, when required.

However transport and handling charges are often a handicap for pre-cast concrete grills. In addition, this flooring has some problems when the air flow has a very high H2S concentration. Concrete gets corroded in these cases and a replacement of the floor has to be made, sometimes after a few years.

  The UK company Hahn Plastics ltd, which is part of the Hahn Group, Europe's leader in the development and manufacture of outdoor, technical 100% recycled plastic products, has developed the biofilter raised flooring system Hanit® . Using state of the art technology and moulding tools, along with technical expertise, they have developed an innovative, long-lasting and cost effective floor that is resistant to chemicals, acids and micro-organisms.

   Hanit® has a large airflow surface and it is adaptable to every filter shape. In addition, the flooring is accessible by vehicles up to 3T gross weight (depending on installation).
