Prediction of Trihalomethane (THM) Formation By Using Ultraviolet Absorbance

자외부흡광도(紫外部吸光度)를 이용한 Trihalomethane(THM) 생성량(生成量) 예측(豫測)

In-pipe formation of THM in water distribution systems was simulated by using the continuously and easily measurable parameters such as water temperature, residual chlorine and soluble organic compounds. The concentration of miscellaneous organics which could be the precuror of THM, was measured and represented as the absorbance of ultraviolet at wave length 260 nm. As the results, the developed equation in this study showed a more reliability on the change of THM than the normally regressed equation. In addition, the simulation was successfully fitted in the actual water treatment and distribution systems. Of the THM components, dibromochloromethane was the main cause dropping the overall reliability in the simulation.
