The Scale and Antiscale Laws of the Main Ions in the Recycling Cooling System Used Reclaimed Water

Abstract:

In recycling cooling system used reclaimed water, the main ions of the reclaimed water must form chemical scales with the increase of temperature and concentrate ratio , In order to control the formation of scale, we must control the fouling ion in the reclaimed water.In this paper the influence laws of Ca²⁺, Mg²⁺, HCO₃^- , SO₄^2-, PO₄^3-, NH₄⁺ , NO₂^- , NO₃^- in reclaimed water on the scale inhibition are researched . The experimental results show that Ca²⁺, HCO₃^- , PO₄^3- in reclaimed water have negative impact on scale and antiscale ;Mg²⁺ and NH₄⁺ have positive effect on scale and antiscale;and SO₄^2-, NO₂^- , NO₃^- hardly affected on scale and antiscale.
