摘要

Water treatment process with phosphates difficult to dissolve containing crystallized silicic acid, avoiding with its use the oxidation of the metal surfaces with which it comes into contact, characterized because for this purpose it will be added phosphates difficultly soluble containing about five tenths to ten a hundred percent of crystallized sicilic acid after being cooled slowly so that on a debit-soher radiograph you can see the corresponding lines of silicon dioxide.
