Treatment of Wastewater in Anaerobic Fixed Bed Bioreactors
Industrial organic waste water is usually treated directly in an internal or public sewage treatment plant which is highly cost-intensive.The anaerobic digestion of those waste waters is sometimes difficult to control.The University HAWK is working in a project about this topic,where a fixed bed reactor is investigated for flexible operation and gas-production.For this reason a semi-industrial pilot plant was developed and the capability will be tested on several sites.The gas production ought to run according to companies demands and is integrated in the operation and processes.This flexible plant is specifically designed to deal with small amounts of waste water with low organic compounds and even sometimes discontinuous loading rates.The process is tested in a beverage factory.The reactor was implemented to the existing infrastructure.The assessment of the measurements shows,that this fixed bed reactor can handle the organic substances of the waste water very well and reduce them significantly.Even fluctuating loads and a low organic concentration do not harm the process.The effect of power generation is an additional benefit for this system.This innovative approach with low energy input and additional profit from power sales turns the waste water treatment on site into a real alternative to the conventional treatment.
