For example, for municipalities facing average to high energy and disposal costs, Siemens offers the Cannibal® Solids Reduction System that reduces the amount of biosolids produced during biological treatment.  The numerous plants that have employed the technology in combination  with recommended aerobic processes have reduced biosolids an average of 50%.  This not only saves biosolids disposal costs, but can cut down dramatically on aeration energy demand of the plant.  The technology can be retrofitted into existing plants or be designed into new ones.  The attractive payback economics achieved at U.S. average energy and disposal costs become even more attractive when disposal costs exceed $35/wet ton and/or electricity climbs above $0.07/kwh. 

Siemens offers innovative Anaerobic treatment technologies that increase biogas production and capture.  The Crown® Disintegration System increases the gas yield from the anaerobic digester by as much as 30%. At the same time, it reduces sludge for disposal by up to 20%, thus drastically lowering disposal costs.  Siemens also offers a new Sludge Belt Dryer that efficiently uses biogas and other low grade heat sources for sludge drying.

Our portfolio includes a variety of technologies to increase energy efficiency, including Aerated Anoxic processes and SMART BNR Controls that minimize use of energy in nitrification/denitrification.  Our innovative MemPulse MBR is another energy saving technology.  But we offer more than just technology. Engineers and municipalities can utilize our biological expertise to help objectively decide which biological process fits a particular plant need.  The Siemens energy calculator is one such tool that considers trends in energy costs as well as turn down scenarios of a particular project to compare best alternatives.

Finally, we can help turn projected energy and disposal cost savings into capital to finance projects on a pay-as-you-go basis. Financing through alternative delivery options is becoming an approach of choice to stretch capital improvement dollars.
