A bio-filter uses the same bio-mix as a bio-bed but it doesn’t require turf, and it uses a series of bulk containers rather than a pit. A bio-filter is usually smaller than a bio-bed and would generally be built above ground.

A bio-filter comprises of a number of bulk containers that form the equivalent to a liner in a bio-bed system. This set-up encourages a drainage system. A bio-filter can be more suited to smaller operations or where limited liquid production is calculated. Waste exemptions allow both bio-beds and bio-filters to treat up to 15000 litres of spray waste per annum. The pump in a bio filter is controlled by a timer that works in 2 to 3 minute periods 3 to 4 times per hour.
