In 2004-2005 LIFETECH`s laboratory worked out an advanced oxidation process (AOP) for removal of dioxins and furans (PCDD/F), chlorophenols and other contaminants from the BCD process wastewater. Consequently, our technology was installed and from April 2006 successfully used in the `Spolana-Dioxins` Project at SPOLANA a.s. in Neratovice, Czech Republic, as a part of Special Wastewater Treatment Plant. Our supply consisted of an ozone generator with the output of 5 kg O3/h at 10% w/w ozone concentration, two reaction tanks with mixing systems, a vent ozone destructor, and a control system. The world largest project for removal of PCDD/F was managed by BCD CZ a.s., a subsidiary of Thermal and Chemical Soil Remediation Ltd.

Chlorine dioxide is a well-known disinfectant for drinking water with many advantages over chlorination. Today there are estimated to be over 900 public water systems using chlorine dioxide for water disinfection world-wide. Also in Australia it is approved for a wide range of uses. However, the acceptance of chlorine dioxide in Australia as a disinfecting agent for drinking water has been hampered by the crude methods available for generating chlorine dioxide – methods that require relatively complex equipment and/or produce impure chlorine dioxide with many undesirable impurities.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality. Control of water pollution was once concerned mainly with treating wastewater before it was discharged from a manufacturing facility into the nation`s waterways. Today, in many cases, there are restrictions on wastewater that is discharged to city sewer systems or to other publicly owned treatment facilities. Many jurisdictions even restrict or regulate the runoff of stormwater — affecting not only industrial and commercial land, but also residential properties as well.
