Actinomycetes and fungi in surface waters and in potable water.
In Finnish lakes and rivers used as water supplies, mesophilic fungi and actinomycetes were common, whereas thermophilic fungi and actinomycetes were present only in low concentrations. Fungi and actinomycetes were more abundant in eutrophic and mesotrophic lakes than in oligotrophic lakes. River water contained more thermophilic actinomycetes and fungi and mesophilic actinomycetes than did lak...
متن کاملHigh frequency sonoluminescence in sulphuric acid and phosphoric acid
Multibubblesonoluminescence (MBSL) emission spectra at different forcing frequencies ( 20, 580, 850 KHz and 1.1 MHz) in Sulphuric acid and Phosphoric acid, under different noble gases atmosphere ( Ar, Xe and He) have been investigated. Using lower frequency we observed the presence of new emissions lines which may indicate the formation of ionized species with very high energy level inside the ...
متن کاملThe Recovery of Uraniumfrom Phosphoric Acid
Commercialization of three processes (OPPA, DBPA-TOPO and OPAP) has shown that the DEPA-TOPO process offers the best technology available today for the recovery of uranium from wet-process phosphoric acid. Uranium recovery plants using this process have been successfully operated in the United States, Belgium, Canada and Taiwan. Operating experience from these plants has led to a significant re...
متن کاملContinuous Melt Suspension Crystallization of Phosphoric Acid
A continuous melt suspension crystallization process has been presented for the purification of the phosphoric acid in this study, which is performed in the cascade of a mixed suspension mixed product removal (MSMPR) crystallizer and a gravity wash column for the subsequent solid-liquid separation. Dynamic behavior in the crystallizer and role of reflux ratio on the purification efficiency of c...
