Since 2006 H2Office has advised the WWTP Geldersheim (50.000 EP) in almost all operational fields. Step by step the effluent quality, energy consumption and energy production should be optimized.
Our projects unify experience, expert knowledge and good teamwork. All of them can serve as a reference.

WWTP Geldersheim (Bavaria, Germany) - Optimization of operation, energy consumption and energy productionThe problemOur solution
Due to temporarily shortages in oxygen supply, the secondary treatment was examined. The necessary adaptation of the aeration system, including the automatic control, was planned and supervised by H2Office. Since then the NH4-N effluent concentrations have been stable and the energy consumption for aeration is very low and on benchmark level.
For the commissioning of the new precipitant dispensing unit for chemical phosphorus removal, a special concept for operation and automatic control was developed.
In 2007 a rough analysis of the energy consumption was conducted together with an economic analysis about co-fermentation with waste greases and food and kitchen waste.
Starting from 2009 until 2011 a full scale test for co-fermentation with the mentioned substrates was performed, resulting in an increase of gas and electricity production of the WWTP Geldersheim by 20 %. At the same time a detailed energy analyses of energy consumption was conducted, based on the previous rough analysis. The implementation of the recommended measures has started 2012 and is on-going.
During the installation of a new process control system the data processing system was adapted to the needs of the operator, according to the specifications of H2Office. The goal was to use the huge pile of measured data more efficiently. This is not only for the control of effluent quality, but also for economical aspects like energy efficiency.
At the beginning of 2011 H2Office performed a cost-benefit analysis concerning the installation of a new CHP. In the same year the planning process started. In spring 2012 the new CHP unit went into operation.
