82-01: Biofouling Control in Recycled Cooling Water With Bromo ChloroRecycled cooling water can contain very high levels of organics, creating a potentially significant Biofouling problem on heat transfer surface. A system in which all treated process waters were added to the cooling water system, and the cooling water was recycled through a sidestream softener was studied. A variety of Biofouling monitoring systems were evaluated; as were control chemicals.
