What is calgon conditioning why it is used?

What is calgon conditioning why it is used?

– Addition of calgon to boiler water to prevent sludge & limescale formation is called calgon conditioning. – This prevents damage to heating element, pipes & drums of washing machine. – At higher temperature, calgon converts calcium salts into soluble complexes so they are easily removed.

What is calgon conditioning in Engineering Chemistry?

Engineering Chemistry Questions and Answers – Calgon Conditioning. Explanation: Calgon converts the scale forming impurity like CaSO4 into soluble complex compound which are harmless to boiler.

What is used for calgon conditioning?

Calgon conditioning: Calgon = sodium hexa meta phosphate The process involves the addition of calgon to boiler water.

How does colloidal conditioning work?

In chemistry, a colloidal conditioning is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. To qualify as a colloid, the mixture must be one that does not settle or would take a very long time to settle appreciably.

What is calgon conditioning How is it better than phosphate conditioning?

In calgon Conditioning, the added calgon forms soluble complex compound with CaSo4, thereby it prevents the scale and sludge formation in water. this soluble complex does not cause any problem in boilers. 2Na₃PO4 + 3 CaSO4 —> Ca₃(PO4)₂↓ + 3 Na2 SO4. Hence calgon conditioning is better than phosphate conditioning.

Is calgon conditioning applicable to low or high pressure boilers or both?

c) Calgon conditioning: Calgon is the trade name of sodium hexa meta phosphate- Na2 [ Na4 (PO3)6]. With calcium ions it forms a soluble complex and prevents scale and sludge formation. It is used for high and low pressure boilers.

What is calgon conditioning Slideshare?

Internal Treatment: 4) Calgon Conditioning :  It involves the addition of calgon or sodium hexametaphosphate to boiler water.  This substance reacts with calcium ions and forms highly soluble complex and thus prevents the precipitation of scale forming salt.

What are scales and sludges?

If the precipitation takes place in the form of loose and slimy precipitate, it is called sludge. On the other hand, if the precipitated matter forms a hard, adhering crust/coating on the inner walls of the boiler, it is called scale.

What is calgon conditioning example?

Calgon conditioning: It is the process of addition of calgon or sodium hexametaphosphate to boiler feed water. The calcium ions (responsible for scale / sludge formation) are complexed by calgon to form a soluble complex and hence prevented from their scale forming action.

Why is calgon treatment better than phosphate conditioning?

In calgon Conditioning, the added calgon forms soluble complex compound with CaSo4, thereby it prevents the scale and sludge formation in water. 2Na₃PO4 + 3 CaSO4 —> Ca₃(PO4)₂↓ + 3 Na2 SO4. Hence calgon conditioning is better than phosphate conditioning.

What is internal conditioning?

Internal Treatment (Internal Conditioning) of Boiler Water. Internal treatment involves the addition of chemicals directly to the water in the boilers for removing scale forming substances which were not completely removed in the external treatment. The chemicals added for this purpose are called Boiler compounds.

Which conditioning is better than phosphate conditioning?

this soluble complex does not cause any problem in boilers. on the other hand, in phosphate conditioning, Sodium phosphate is added to the boiler water so that precipitate of calcium phosphate is formed. Hence calgon conditioning is better than phosphate conditioning.

How does Calgon conditioning work in boiler water?

Calgon conditioning involves the addition of Calgon or sodium hexametaphosphate to boiler water. this substance interacts with calcium ions forming a highly soluble complex and thus prevents the precipitation of scale-forming salt – Sodium metaphosphate is called calgon.

How is calogen used in a medical setting?

Calogen is suitable for patients requiring electrolyte restrictions, can be used to replace milk in protein restricted diets and can be used as an energy enhancer in tube feeds and oral nutritional supplements. Calogen is a Food for Special Medical Purposes for use under medical supervision.

What can calogen be used for on a protein restricted diet?

Calogen is suitable for patients requiring electrolyte restrictions, can be used to replace milk in protein restricted diets and can be used as an energy enhancer in tube feeds and oral nutritional supplements. For enteral use only.

Is it OK to freeze calogen after use?

Calogen is not suitable for freezing. Always replace lid after use. This is intended to show suitability of products for religious or dietary reasons. Some products may be suitable for kosher or halal diets but only products with Kosher approval or Halal certification have been identified here.
