Wastewater disinfection with a combination of biocides. |
摘要 |
<p>Wastewater is effectively disinfected while reducing both chlorine consumption and more particularly the levels of residual chlorine discharged from the wastewater treatment plant. The wastewater is first contacted with a sufficient amount of chlorine to satisfy the chlorine demand and to obtain as low a residual level of chlorine as possible. After the chlorine demand has been satisfied, the wastewater is disinfected with an effective amount of 2,2-dibromo-3-nitrilopropionmaide. <IMAGE></p> |
