Two separate experiments confirmed that biomass accumulation was higher in the presence of orthophosphate at high water temperatures (20 C), whereas no significant differences were identified in biofilm ATP concentrations at lower water temperatures (<20 C). If used as a paper glue, there is a tendency for the sodium silicate joint to break gradually after a few years, at which point the paper surfaces are no longer holding together. Founded in 1807, John Wiley & Sons, Inc. has been a valued source of information and understanding for more than 200 years, helping people around the world meet their needs and fulfill their aspirations. An elevated sodium silicate dose (48 mg L1 of SiO2), however, dispersed the biofilm, resulting in elevated effluent ATP concentrations. provided that the correct acknowledgement is given and it is not used for commercial purposes. Current studies tend to search for environmentally friendly modification methods. Namely: Trivalent, Bivalent and Monovalent. In a pilot-scale study with annular reactors (ARs) fed by cast iron pipe loops, biofilm ATP concentrations were substantially lower on polycarbonate coupons in the sodium silicate-treated AR than on those in the orthophosphate-treated AR when the water temperature exceeded 20 C.
