Bridge prevention is key to successful sewage sludge handling applications

Solids content of sludge cake in sewage sludge handling operations is a persistent problem. Traditional bridge-breaking technology fails to adequately address bridging in the resulting difficult-to-convey sludge applications. More recently, improved technology, such as NETZSCH Pumps & Systems’ aBP-Module®, has proven to be highly effective in ensuring bridge prevention.
