Sewage Odour Control Pilot Trials in Spain

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.

DSCI0024

JSF are leaders in the aluminium structures, solid tank covers (below) and floating
tank covers market place. Odour control was 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.

DSCI0272

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.

Industrial VOC Abatement

ASK Piearcey designed a range of split bed rect-annular carbon adsorbers for the adsorption of methyl chloride on a coating process.

The equipment was manufactured to our designs by EIS Ltd

ASK Piearcey were asked to investigate the possible release of VOCs from a printing process. Smoke testing and flow measurement from ASK Piearcey demonstrated clearly that there were no fugitive emissions from the process. By investigating the prime VOC sources in the process ASKP Ltd were able to advise the client regarding minor extract philosophy changes to improve stack emissions, which were found to be compliant

VOC Abatement

VOC Abatement

ASK Piearcey were asked to provide designs for movable carbon adsorbers to assist in the removal of VOCS from combined vent and breather sources, some of which ere already treated via a scrubber. Modifications to the scrubber operation involving re-use of another waste water stream improved the scrubber performance and hence allowed for an improvement in design carbon bed life. The units are due to replace existing static adsorbers and will provide for easier carbon change and reduction in on site, associated hazards.

The project was under taken with Transvac Ltd who built the original scrubber.

Industrial Odour Control

ASK Piearcey  designed the adsorbers for the removal of odour generated by the baking of pet food treats.

The adsorbers were then fabricated by the customer with ASK Piearcey Ltd assisting with the sourcing of the carbon. ASK Piearcey  also assisted the customer with the choice of pre-filter to remove the oil aerosol present in the off-gas.

ASK Piearcey were asked to investigate the odorous releases from a high temperature autoclave sterilisation process. Tests were conducted for hydrogen sulphide and ammonia and then a full scale abatement system was designed to handle the fume and other extracts.
