The invention relates to a process of producing chlorine dioxide comprising the steps of reducing chlorate ions in an acid reaction medium maintained in a reaction zone of a chlorine dioxide generator, which reaction medium contains alkali metal ions and sulfate ions, so to form chlorine dioxide and a solid salt of acidic alkali metal sulfate. The process further comprises the steps of separating said solid acidic alkali metal sulfate from the reaction medium, contact- ing said solid acldic alkali metal sulfate with an aqueous medium in a mixing tank to effect at least partial conversion to neutral solid alkali metal sulfate, separating the at least partially neutralized solid alkali metal sulfate from the aqueous medium on a rotary drum filter operating with vacuum inside and with part of the drum submerged in a slurry of the at least partially neutralized solid alkali metal sulfate and the aqueous medium, and forming an acid filtrate.
THIS IS THE ABSTRACT This is the first line of the first paragraph of the abstract. This is the second sentence of the first paragraph of the abstract. And so on, and so on. This is the third line of the abstract text. This is generic text for the remainder of the abstract document. & this is a special character. | this is another special character. \ this is another special character. [] this is the square bracket special characters separated by 3 spaces. This is the less than < special character followed by the > greater than special character. The temperature is 37.9°: usage of the degree symbol. <= less than or equal is not as much as >= greater than or equal. 99¢ is almost a dollar ($) but it is NOT $1.00¢. 3 x 2 = 18 ÷ 3 This is not rocket science. This is the ± plus or minus symbol/special character. This is the ® registered trademark symbol which is a protected mark consisting of words and/or symbols which identifies the source of goods, services and/or quality and which is registered with the govemment. So there! This is the © copyright symbol which provides the protection of works of authorship, such as writings, music and works of art which are tangible. So there! I'm not sure what this µ special character is; it's apparently called a micro sign. Here we have the § SECTION special character. There are 3 of these symbols displayed: Ø Ø Ø ~ and this little thingy is called the NOT SIGN. Well, isn't that SPECIAL. Now everybody knows the exclamation mark! Some use the double exclamation marks!! How `bout that?!? And lastly we have the ^ circumflex accent, probably never used in the English language. Here it is on an E ê, and here it is on an A â, and on an Iî, and on an Oô, and on a Uû. And lastly we have the ^ circumflex accent, probably never used in the English language. Here it is on an E ê, and here it is on an A â, and on an I î, and on an O ô, and on a U û. And lastly we have the ^ circumflex accent, probably never used in the English language.
