Study of sealing mechanisms in aerated stabilization basins for bleached kraft wastewater sludges

Chen, Michael Ching-li. January 1984 (has links)
The purpose of this study is to investigate the possibility of using the Bleached Kraft wastewater sludges as a sealant to a permeable soil structure which could contain these liquids. The sludges used are either self-contained in wastewater, produced from treatment processes, or from the addition of chemical coagulant to the wastewater. / The mechanisms of the sludge sealing phenomena which were investigated individually are divided into physical, physico-chemical, biophysical and bio-physico-chemical types of seals. Coarse sand #24 was found suitable for this sealing study as a particle size cut. Among the types of sealings studied, the bio-physical type of seals is the most effective. The physico-chemical type of seals is effective in the initial stage of sealing. The coefficient of the permeability is reduced from an average of 6.4 x 10('-2) cm/sec to 1.0 x 10('-6) cm/sec in a period of 24 hours, with a risk of leakage of less than 1% of the total effluent. / A long-term stability of using sludges as a liner to the wastewater pond has become a substantial issue. Alum was originally chosen as an effective coagulant for forming a layer of sludge for physico-chemical types of sealing. However, after the stability analyses, one finds that alum sludge is not a stable material under commonly-found hydrostatic pressures and high pH ranges. The results of the research shows that one of the alumino-silicate sludges is much more stable than that of alum sludge. The relatively stable alumino-silicate sludge was obtained from one of the coprecipitations of sodium-silicate and sodium aluminate in a BKME solution. / The economic impact of using alumino-silicate sludge is significant. The cost comparison study shows a cost ratio in the range of up to 1:10 as compared to conventional lining material. The results can be used for the implementation of field work in sludge sealing practice. In addition, this investigation could form an excellent foundation for further studies on other effluents with different parameters.
