Water and Wastewater Membranes need to be protected against fibrous debris that not only create excessive membrane cleaning cycles and labor intensity, but too often abrade & damage the membrane surfaces, as well as clog the aeration manifolds that scour the membranes. Pre-Screening has become extremely important in protecting both membrane warrantees and membrane efficiency. This paper emphasizes the importance of fine screening with data showing how short, fine cotton-wool fibers, hair & filamentous algae will pass through 3mm and 2mm aperture screens and “recombine” downstream into stringy, rag type debris that increases maintenance and membrane cleaning cycles. Pre-Screening + Membrane Filtration is a “Process!”
