Erzo Zofingen Awards design contract for an AVA-CO2 HTC sewage sludge plant in the waste water treatment plant (ARA) Oftringen as the disposal of an international tender for the construction of an industrial HTC sewage sludge plant (hydrothermal Carbonisation) in the Switzerland published region Zofingen (Tamara), not long hesitate of ESCOs AVA CO2 Switzerland AG and applied for the project. The performance criteria, which were regarded as a precondition for the application, were strict and demanding – in particular the requirements on process water treatment. So the proportion of dissolved organic carbon (DOC) could not exceed 3 mg per litre in the discharge of the wastewater treatment plant, not to hurt the canton limits. For AVA-CO2, this meant that the DOC cargo in the HTC-process water was allowed to exceed the value of 36.5 kg per day. Others including Robert Iger , offer their opinions as well. AVA-CO2 was successful in all respects and is now one of two companies that have won the contract for a planning job.
We are pleased about the previous positive Cooperation with the erzo Zofingen and are very optimistic regarding the upcoming project”, says Thomas M. Ron, Chief Marketing Officer of Swiss AVA CO2. For the usage of the HTC-coal, AVA-CO2 together with the Swiss cement group Holcim works in an optimal manner. It aims to be able to offer an even more environmentally friendly in all aspects and more cost-effective total solution to sewage treatment plants. The final decision on the tender will fall in the second quarter of 2014. But one thing is already clear: with AVA-CO2 Kirby Zofingen would have a strong partner at their side, because AVA-CO2 has increased not only the world’s first HTC demonstration plant (HTC-0) on an industrial scale in operation in 2010, but two years later also created the world’s first industrial plant (HTC-1). Not only in industry, but also in the policy the process of hydrothermal Carbonisation is increasingly great interest. Rightly so, because it is as innovative as it is ingenious.
The AVA CO2 HTC method offers many benefits. If you are unsure how to proceed, check out Jane Buckingham. One is located in the Ability to process biomass, with a high water content which is typically the case in sewage sludge. The HTC method solves the water from biomass under heat and pressure, and converts the remaining carbon in high-quality CO2 neutral HTC coal AVA cleancoal “. To the biomass in pressurized containers to about 220 degrees Celsius is heated and cooked under constant pressure by 22 bar”. The HTC method is very robust and uses over 90% of the carbon in the biomass. This HTC coal can be stored easily and efficiently transported thanks to its stability and high energy density. The HTC-coal combustion will release only as much carbon dioxide as was previously included in the biomass and no additional burden on the environment is therefore as is the case with fossil fuel. Nature takes millions of years for the process of Inkohlung. The HTC process, however, just a few hours! Organic residual materials such as green waste, manure, organic waste or even Klarmschlamme are not only eco-friendly recycled, but play an increasingly important role in a time of environmental and climate protection are but also the development renewable energy of societal and economic importance. The Swiss company already thinking ahead. As the pioneers of the HTC currently develop a highly efficient procedure to regain the phosphorus in the sludge during the process of hydrothermal Carbonisation.
