The Influences of Main Ingredients of the Reclaimed Water on Calcium Carbonate Scale in Recycling Cooling System
The main risk of reclaimed water reused in industry is to control fouling.The main ingredients in reclaimed water form the chemical scale which is one of the main components of the fouling in the recycling cooling system.The main chemical scale of reclaimed water is carbonate scale (calcite).In this paper,by using the actual reclaimed water which reused as make-up water in Beijing Thermal Power Plant to simulate the 4 times concentrate ratio recycling water to study the influence of main ingredients of reclaimed water such as pH,soluble silica,the most content of anions and cations on carbonate scale.The experimental results show that pH,soluble silica,calcium ion and alkalinity have greater influence on scale inhibition,but magnesium ion,chloride ion and sulfate ion have smaller influence on scale inhibition.
