Microbial growth on ion exchangers

摘要: Abstract Bacteria in ion exchange resin beds find enough organic material to live on—adsorbed matter from the water passing through as well substances which may be released material. They settle on outer surface of but are not securely attached. Nevertheless, contaminated exchangers cannot sanitized by flushing, backflushing or other rinsing processes. Regeneration removes a part microbial population is sufficient for sanitation. If units can left standing regenerant during off-periods, bactericidal effect utilized. A continuous mode operation prevents bacterial growth certain extent. Recirculation off-periods acts fermentation process and prevent growth. Addition silver suppresses period time elapsing until silver-tolerant has developed. An increase tolerance takes place when exposed sub-toxic concentrations. Satisfactory disinfection carried out with peracetic acid (0.01%, 1 h). remanent produced combination conservation based needed development flora exchanger. Ion must subjected routine monitoring all cases where hygienic implications involved their usage.
