Modeling the die-off of
E. coli andAscaris in wastewater-irrigated vegetables: implications for microbial health risk reduction associated with irrigation cessationThis study assessed the die-off of Escherichia coli (E. coli) and Ascaris suum on lettuce (Great Lakes 118) and cabbage (Brassica oleracea var capitata) in wastewater-irrigated fields using comparative mathematical die-off models. The study revealed that none of the survival curves of E. coli and A. suum was best fitted with the log-linear model, indicating that the classical first-order ...

Food Grade Perlite Rapid Filter Aids
Perlite provides 20-50% greater density than other filter aids, which is important to consider when comparing costs. There is only a density range of 110 to 270 kg/m3 (7 to 17 lb/ft3 ) for perlite filter cakes. The dry density of perlite filter aid varies between 100 and 200 kg/m3 (6.2 to 12.2 lb/ft3). Perlite filter aids can substantially reduce filtration costs without compromising performance ...
