  10. Maintaining Greater Value In Bar Screen Performance 2/20/2019

    Before wastewater can be treated to minimize biochemical oxygen demand (BOD), nutrients, and pathogens, it is important to eliminate as much debris as practical, as early on in the treatment plant as possible, to avoid clogging pumps or compromising downstream performance. Careful consideration of design and operating factors can minimize total lifecycle costs and maintenance effort while protecting screening efficiency.
