Biological odour cleaning

This Bigadan concept is a two step system which deodorizes the air from receiving and mixing tanks as well as the receiving hall by removing hydrogen sulphide through a pre and main filter.

This pre filter is a fibre-glass tank and the main filter is a concrete tank containing a special material which has excellent filter properties and through a biological cleaning process reduces hydrogen sulphide and other sulphur components – and thereby any unpleasant odours - in the air considerably.
