Research on Scale Inhibition of Green Scale Inhibitors Used in the Industrial Recycling Cooling System with Reclaimed Wastewater

Abstract:

The reclaimed water of domestic sewage reused in recycling cooling system has been widely spread and applied. Chemical scale inhibitors are the most economic and effective measures to prevent condensers and circulating pipes from scaling currently. Green scale inhibitor are highly regarded for their non-toxicity, phosphate-free, reproducibility and biodegradability. The paper selects two kinds of new green scale inhibitors used in the recycling cooling water of Beijing Thermoelectric Plant. By the measuring the scale inhibition rate, scaling amount, turbidity and SEM, it shows that Polyepoxysuccinic acid (PESA) is worth spreading and applying in the industrial recycling cooling system with reclaimed wastewater, for its high scale inhibition rate, good dispersion, low consumption, high economy and practicability.
