this is so bcoz even if cabonate conditioning forms soft scale , but it is a SCALE phosphate conditioning forms soft sludge , which can be removed by blow down operation . so its better than carbonate condiitoning
The compound with formula Na3PO4 is named "sodium phosphate", "trisodium phosphate", "sodium ortho-phosphate", or "trisodium ortho-phosphate".
potassium phosphite
Phosphate is made of phosphorous and oxygen. The formula for the phosphate ion is PO43-.
Sodium phosphate is a generic term for the salts of sodium hydroxide and phosphoric acid (soluble in water). They are:sodium dihydrogen phosphate, commonly termed monosodium phosphate, (NaH2PO4), is also known as "sodium phosphate, monobasic".disodium hydrogen phosphate, commonly termed disodium phosphate, (Na2HPO4) is also known as "sodium phosphate, dibasic".Trisodium phosphate, commonly shortened to just sodium phosphate, (Na3PO4), is also known as "sodium phosphate, tribasic".sodium aluminium phosphate, (Na8Al2(OH)2(PO4)4).

This process is used in internal conditioning of boiler water, on the one hand and conditioning of cooling and process water, on the other orthophosphate such as trisodium phosphate and complex phosphates scuh as sodium hexametaphosphate are both used in steam boilers to precipitate whatever small amounts of calcium ion reach the boiler water through the pretreatment system or by leakage through the condensor. sodium hexametaphosphate is advantageous where the boiler water naturally tents to become too alkaline because it reduces this excess alkalinity by reverting to an acid orthophosphate in the boiler. Sodium hexametaphosphate is also widely used for minimizing the corrosion and pickup of iron by water in circulating cooling systems, in plant water distribution systems, and in municipal systems.

By considering the valency of sulfate over phosphate, sulfate can be distinguished from phosphate. Sulfate has a valency of 2 where phosphate has 3.
Phosphate groups
The compound name of PO4 is phosphate.
The DNA backbone consists of alternating sugar (deoxyribose) and phosphate groups. The sugar-phosphate backbone is formed by the covalent bonds between the sugar of one nucleotide and the phosphate group of the next nucleotide. This forms a repeating pattern of sugar-phosphate-sugar-phosphate along the DNA strand.
