Zyaad,
The type of scale that builds up in Sludge lines is often Magnesium Ammonium Orthophosphate Hexahydrate commonly known as Struvite. Hydropath Technologies out of the UK have a technology to prevent this build up and eliminate existing buildup. See Hydropath.com for contacts in your specific area.
Never mind the chemicals, they are nasty acids and physical removal which can create other issues with your systems. HydroFlow is the way to go.
