PpTek at SWANA conference in San Diego

The Product Development department of PpTek presented a technical paper at the SWANA conference in San Diego, California, USA on March 10th 2005.

The presentation, given by John Hayward, was a great success and prompted many questions during the following session and in the associated exhibition.

John Hayward commented “The reaction, and following comments we received, indicates that PpTek has a real solution for operators which is now ready to be delivered in production”

The patented regenerative solution was hailed as an important innovation in solving the Siloxane contamination issue in the landfill  and sewage treatment  industry.

The paper covered detailed information of the siloxane problems facing operators in the Landfill and Sewage gas industry,  current solutions and details of PpTeks filter technology.

A copy of the dissertation is available from PpTek upon request.

The first production BioGas AK successfully installed.

The first production BioGas AK (BGAK) has now successfully been installed on a Landfill site in the UK. The Waste Recycling Group (WRG) site at Rigby, near Wigan, hosts the first unit.

The unit has performed to the PpTek specification removing the Siloxanes in the Landfill gas to less than 1mg/m3, with the media successfully regenerated automatically on site. The pressure drop across the filter exceeded design parameters dropping only 0.7mb.

David Hayward, Director of Product Development, commented:- “We are delighted that the BGAK performed almost straight out of the box to our specification”. David also paid tribute to the help given to PpTek during the installation at Rigby “The staff at Rigby could not have been more helpful and supportive during the installation and commissioning period, nothing was too much trouble for them”.

Bill Cowing, Director of Sales and Marketing added “ The last 3 years of R&D and  pre production test models has proved invaluable to enable PpTek to bring this important innovative solution to market”.

The unit is now  being put through an accelerated life test at Rigby.
