What is the difference between slime and dirt?
Sludge refers to dirt that has settled; it covers a wide range of substances and is an umbrella term for all the impurities in a system!
Clay is relatively soft, while scale becomes quite hard.
Clay is generally composed of organic matter and microorganisms, and it has an odor； Scaling is generally the precipitation of inorganic substances, such as calcium and magnesium salts, and it is odorless.

Slime is a sticky substance formed by microbial communities and their secretions. The components of dirt include scale, sludge, corrosion products, silt, suspended solids, etc. Slime is part of dirt; it is a soft deposit formed by microorganisms. The surface of the clay has a sticky mucous substance, giving it a slippery feel to the touch. In fact, the sediment in the system will not be pure microbial sludge, but will contain other types of dirt. Sludge refers to the sticky, soft mud that accumulates on the walls of heat exchangers, cooling towers, tanks, pool bottoms, and pipes. Its composition is mainly microbial sludge, and it also contains some scale, corrosion products, silt, suspended solids, etc.
