Hardness of water is due to the presence of calcium and magnesium salts.
Genrally, soaps consist of Na salts of higher falty acods like sterai. oleic, obrc etc. which are highly soluble in water amd thus exert their cleansing action . If Ca and Mg salts are present , these react with soluble Na soap to form insoluble salts of Ca and Mg.
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
The workers had to wade through thick sludge to clear the clogged drain.
Metal sludge is typically composed of various metal particles and debris that may or may not be ferrous. Ferrous metals contain iron, while non-ferrous metals do not. Some metal sludge may contain ferrous metals, depending on the source and composition of the sludge.
On average, 1 gallon of sewage sludge can contain roughly 0.2-0.4 pounds of carbon. The carbon content can vary depending on the source and treatment processes of the sewage sludge.
Sludge density affects the settling characteristics, dewatering efficiency, and treatment processes in wastewater treatment plants. Higher sludge density can improve settling and dewatering, leading to more efficient treatment and reduced processing costs. Conversely, lower sludge density may require additional treatment steps or longer processing times.

distance is the separation between two points and scale is the type of unit you adpt to measure anything.

There are many ideal boilers for critics. Some ideal boilers for critics include the Buderus boilers, the ORLAN boilers, and lastly the Crown Boiler company boilers.
In bearings.
Any character that is not favored by selection is disadvantageous e.g. loss of pollen tube in land environment .
Disadvantageous
dimineralised water is also preferable to tap water for use in model steam engine boilers and model engines of other types. Mineral build-up resulting from the use of tap water in model boilers can severely reduce the efficiency of the boilers if run for long periods. This build-up is called boiler scale.
All boilers are not coil type think of the pork chop steam boilers AKA cast iron sectional

Paper sludge is the leftover chemical sludge that is expelled when making paper. This sludge reduces as paper is recycled.
