Sludge is usually caused by the presence of water in the oil, and can accumulate with use. Ways to minimise sludge production and accumulation includes performing frequent oil changes, performing mechanized engine flushing, or de-sludging, using modern synthetic oils and always following the manufacturer's engine maintenance routine, particularly if the vehicle is oftern used for short urban runs.
Hard Scale(Scale) - Forms in steam boiler -Has the appearance of a white and brown concentration -smooth texture Soft Scale(Sludge) -Forms in the hot water heaters -Appears as a thick ,brown or black sludge
Chemically sludge is obtained when precipitating soluble or insoluble chemicals present in the water or any kind of effluent coming out of chemical industries. Generally iron was used as an precipitate pollutants present in waste water. the final product after precipitation is called chemical sludge which is filled in a land into heap or used in road construction. Biological sludge is formed when microorganisms are used to degrade toxic chemicals present in waste water. The excess biomass formed is termed as biological sludge which contains adsorbed toxic chemicals in their cells, toxic metabolites formed during degradation of wastes, dead biomass etc.
Paper sludge is the leftover chemical sludge that is expelled when making paper. This sludge reduces as paper is recycled.
3 types: Sewage sludge Septic tank sludge Industrial sludge ------- The term "sludge" is used in different disciplines to mean different things. For example, there is sewage sludge industrial sludge metal sludge gallbladder sludge engine sludge the muddy gunk on the bottom of a stream or river slushy ice on the ocean an agglutination or aggregation of blood cells

There is no substance in your car that should look like orange sludge. The sludge has to be a foreign material. Try locating the source of the sludge and then work from there.
There are so many different types of sludge that can be created. Sludge types can include but are not limited to chemical.
Sludge - Transformers - was created in 1985.
Sludge - film - was created in 2005.
The snow had turned to sludge.
Removing the water content (dewatering) of the sludge will dry the sludge, making it lighter and easier to move and reuse. (Reuse depends on whether the sludge is toxic and has to be stored safely or, as in human sludge from a sewerage farm, used as fertilizer by farmers, etc ).
sludge dumping is dumping "stuff" from toilets into the ocean
