متن کاملCarbon dioxide in pulp/paper mill stocks: fix or fizz?
The use of carbon dioxide for neutralising pulp mill black liquor residuals and controlling paper machine stock pH has increased dramatically over the past decade. It is replacing, or supplementing, alum and sulfuric acid as the chemical of choice because it does not add any metal or sulfate ions to the water system; an important consideration with the trend to closed loop water systems in pape...
متن کاملMicrobial degradation of organic carbon and nitrogen on diatom aggregates
The major pathways of transformation of particulate organic matter by heterotrophic bacteria are respiration and production of new biomass. Until today only a limited number of studies have measured simultaneously respiration and production by aggregate-associated bacteria. To study their role in the carbon cycle of aquatic systems we have formed model particles from diatoms (Skeletonema costat...
متن کاملFluctuations in the Organic Carbon to Chlorophyll a Ratios for Estuarine Benthic Diatom Populations
C/Chl-a ratios were determined for benthic diatom populations at 6 stations in the Ems estuary. For mixed field populations previous data are not available. Measurements were canied out over a period of nearly 3 years. The data were statistically analysed. Statistically significant differences in rat10 values were indicated within and between years. No indications were found for a statistically...
