 Trace
nutrient and microbial loading in the source water for membrane systems
represents the potential biofilm. Insufficient or inappropriate
feedwater pretreatment can result in rapid loss of membrane system
performance due to the establishment and growth of biofilms on the
membrane surfaces. AquaMem has extensive
expertise in the analysis of system feed streams for chemical and
microbiological parameters that can lead to memrbane biofouing and
performance decline. Our feed stream analyses include (but are not
limited to) total heterotrophic counts as well as direct epifluorescent
microscopy detection and quantification of bacteria and other microbes
that cause membrane biofouling and system performance losses.
Additional analyses include TOC analysis and sensitive biofilm
formation potential (BFP) bioassays for feedwater trace nutrient
loading that can support the rapid in
situ proliferation of biofilms in membrane systems. A full
spectrum of inorganic nutrients are also determined including various
nitrogen species, phosphate, sulfate, iron, manganese, and more. All
data are fully interpreted and reported to clients in hard copy and
electronic formats. Please contact
us to discuss whether a feed stream analysis is appropriate for
your facility. |
