A Study on Bio-Fouling Characteristics of Contemporary Trickle and Modular Splash Fills

摘要

The development and marketing of contemporary modular trickle and splash fills has yielded a perception that any “wire frame model” type fill offers similar resistance to fouling as classic splash bar fills. However, labora-tory testing and real world experiences have shown that these fills exhibit similar responses to bio-fouling problems as film fills with respect to product design and flute geometry. A systematic laboratory method of evaluating weight gain due to bio-fouling and sediment accumulation illustrates the effects that these different design elements have on the actual fouling resistance of this type of fill.
