WELTEC BIOPOWER to Showcase Solutions for the Energetic Utilisation of Organic Waste and Wastewater

At the IFAT, the world‘s leading trade fair for environmental technologies in Munich, Germany, the German company WELTEC BIOPOWER will exhibit its technologies for the energetic use of organic waste and wastewater to a broad industrial and municipal audience. From 14 to 18 May, the globally active biogas plant manufacturer will be present at stand 219 in hall A4. Visitors are invited to approach the company for all questions concerning its tried-and-tested process technology for the establishment and expansion of anaerobic energy plants.

The sewage treatment plant in Burgebrach, Bavaria, demonstrates how a municipal enterprise can effectively reduce its energy
and disposal costs with the help of a biogas plant. For the existing sewage treatment plant, which serves a population of 13,000,
WELTEC has added a sludge digestion unit including energetic utilisation of sewage gas in the combined heat and power (CHP)
plant. The facilities went live in spring 2016. Since then, the sludge has been stabilised with an anaerobic process in the customdesigned
stainless-steel tower following the wastewater treatment in a two-stage trickling filter unit.
Thanks to the installation of the digestion unit, the unpleasant odour emissions around the sewage treatment plant have been
eliminated. Moreover, the digestion reduces the amount of sludge and enables the energetic utilisation of the digestion gas. The
operators also wanted to be able to use all the power and heat generated by the CHP plant for the on-site processes. „Thanks to
our self-supply, we are able to save the electricity costs of about 100,000 kWh/year“, says Arne Nath, Head of Wastewater Treatment
at SüdWasser GmbH, the operator that has supported the town Burgebrach since 2005.
This special plant benefits greatly from the proven technologies of WELTEC BIOPOWER: Firstly, the modular structure of the
stainless-steel plants enables a customer-specific layout. Secondly, such projects draw on the experience that WELTEC has gained
in the establishment of more than 300 biogas plants.
Every single plant has a different substrate structure. Regardless of whether sludge, abattoir waste, production leftovers, or
supermarket waste is concerned, WELTEC guarantees optimum energetic utilisation of the substrates in all cases. This is possible
with the help of smart processes and the comprehensive services and supervision by biologists and engineers.
