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.

What is the difference between sludge and scale?
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
What is a sentence for sludge?
The workers had to wade through thick sludge to clear the clogged drain.
Is metal sludge ferrous or it is non ferrous?
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.
How much carbon is in 1 gallon of sewage 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.
What is the impact of sludge density?
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.
What is the difference between sludge and scale?

How do you remove sludge from boilers?
To remove sludge from boilers, first, ensure the system is safely shut down and cooled. Use chemical treatments or cleaning agents designed for boiler systems to help break down the sludge, followed by a thorough flushing with water to dislodge the debris. In some cases, mechanical cleaning methods, such as using a vacuum or specialized tools, may be necessary to physically remove the sludge. Regular maintenance and water quality management can help prevent sludge buildup in the future.
What is sludge and scale?
distance is the separation between two points and scale is the type of unit you adpt to measure anything.
How are sludge and scale formed in steam boiler?
Mineral deposits from use of hard water.
What has the author J Smart written?
J. Smart has written: 'Full scale studies on the thermophilic anaerobic digestion process' -- subject(s): Biological treatment, Purification, Water 'Aerobic digester sludge nitrogen/metal ratios and the sludge utilization guidelines' -- subject(s): Characterization, Recycling, Sewage sludge, Sewage sludge as fertilizer, Sewage sludge digestion
What are the effects of scale and sludge?
Scale and sludge can significantly impact the efficiency and lifespan of industrial equipment. Scale, which forms from mineral deposits, can reduce heat transfer efficiency and increase energy costs, while sludge, consisting of accumulated debris and organic matter, can lead to blockages and corrosion. Both can hinder fluid flow, cause equipment failures, and necessitate costly maintenance or downtime. Managing these issues is crucial for optimal operation and longevity of systems.
What are some critics' ideal boilers?
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.
Where frictionis disadvantageous?
In bearings.
What Is disadvantageous trait?
Any character that is not favored by selection is disadvantageous e.g. loss of pollen tube in land environment .
Why Demineralised water used in boiler?
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.
What is the antonym for the word advantageous?
Disadvantageous
Why steam boilers are coil type boilers?
All boilers are not coil type think of the pork chop steam boilers AKA cast iron sectional
