Vogelsang_BioCrackThe BioCrack system, Vogelsang says, increases the efficiency of the anaerobic digestion process. Improved efficiency means more gas volume produced in a shorter time, with less residual waste. A German company, Vogelsang has a manufacturing plant in Ravenna, Ohio.

And while there is more than one way to degrade a sludge-like liquid, BioCrack, Vogelsang says, does so using only 35 watts of electricity in a highly adaptable piping format easy to integrate into existing systems. Added to a digestion system, it enhances its performance. The result is better use of organic materials that would otherwise be disposed of in a landfill or applied to farmland.

Properly conditioned, sludge is a homogenous fluid that gives bacteria full access to the biological nutrients that perpetuate fermentation. The BioCrack Sludge Lysing System acts on sludge in an anaerobic digester’s recirculation line.

Arranged in series between the pump discharge and the digester feed, each BioCrack module is a stainless steel tube that houses a high voltage electrode. As sludge enters a module it is exposed to an electric field that degrades its structure, making nutrients more accessible. Bacteria progresses through the digestion process efficiently.

The result is increase in gas output as high as 18%. In addition, conditioned sludge tends to layer less, reducing mixing. Finally, conditioned sludge is easier to dewater, with dry matter reduction also as high as 18%, for reduced disposal and transportation costs.
