A.S.K. Piearcey (ASKPL) have assisted Cover manufacturing specialists JSF Hidraulica (JSF) of Madrid in developing their odour control portfolio in Spain.
After some preliminary design work by ASKPL, JSF have built and tested a pilot system (below) consisting of a bio-filter and a Carbon polisher.
JSF have tried a number of different media in the vessels to find an optimum for sewage odour control.

JSF are leaders in the aluminium structures, solid tank covers (below) and floating tank covers market place. Odour control as a natural progression from their various tank covering projects and they had received a number of enquiries to provide odour abatement with their covers. They decided that a pilot trial was an effective and economic means of developing track record and confidence in the approach suggested by ourselves.

After extensive pilot trials involving various media they have developed a system (with design assistance from ASKPL), which can be used to handle the majority of the sewage odour control applications that they come across. The bio-filter was entirely constructed from aluminium and lined with a chemical resistant liner.

Measurements of air flow, H2S inlet and outlet as well as temperature and irrigation were made and data-logged where practical.
The pilot trial, in Fuengirola (south coast of Spain) was so successful that the plant manager is seeking to replace the existing scrubbers with the bio-filter approach.
JSF have since secured 2 large orders involving bio-filters and carbon adsorbers with design assistance from ASKPL.
