| Summary: | (1) to investigate characteristics of organic polymer 28 cmol kg-1. Quantitative mineralogical analyses showed 8% mica. However, XRD patterns of the sludge indicated that aggregate stability, Atterberg limits, hydraulic been an unsolved problem. The objectives of this study were Boonville sandy loam soil increased the aggregate stability characteristics, nitrogen content and mineralization Charles clay soils. Organic polymer coagulants added during clay or Lake Charles clay soil showed that nitrogen coagulant added during water clarification, which also was compressible. Addition of 0 to 10% sludge into Boonville conductivity, dispersion, crust strength, adsorption confirmed by aggregate stability of the sludge. Cation contamination problem. decreased from 53.1 to 14.4 kg / cm. Metal adsorbing ability determined in this study. Mineralogical composition of due to their resistance to rewetting. The aggregate estimated to be 40% kaolinite, 32% smectite, 20% quartz and exchange capacity of the bulk sludge samples ranged from 8 to exchange sites with organic polymers. SEM and TEM results expansion of the smectite was inhibited by organic polymer from 111 to 138%; and liquid limit from 208 to 320%, which indicated that the sludge was mostly fine aggregates of clay infiltration, dispersion and crusting. The low nitrogen Land application of water treatment plant (WTP) sludge has limit of the sludges ranged from 16 to 66%; plastic limit little fertility and would not produce a groundwater mineralization rate of the sludge showed that the sludge had mineralization rate was not affected by the sludge addition. Mineralogical composition, cation exchange capacity (CEC), Moreover, addition of from 0 to 10% sludge into Boonville nitrogen and exchangeable ammonium nitrogen (NH4+) contents nitrogen, incubation experiment of sludge-amended Beaumont of local Beaumont clay soil. Addition of 0 to 10% sludge to of the Boonville sandy loam soil was reduced by addition of of the sludge were four times and twenty times as high, of the soil from 4 to 13%. Atterberg limit showed that wet organic polymer sludge was similar to local Beaumont clay particles. Dried sludge aggregates were not prone to swell, physical properties significantly, e.g. soil aggregation, plastic states, and shrunk greatly during drying. Shrinkage potential of the sludge or sludge-amended soil were rainfall, and the penetration resistance of the crust respectively, as those of local Beaumont clay and Lake S, and reduced the dispersion of the soil significantly. sandy loam soil greatly reduced the crusting produced by sandy loam soil increased the infiltration rate of the soil scanning and transmission electron microscopy (SEM and TEM), sludge had wide ranges of moisture contents in semi-solid and sludge, and (2) to determine the effects of the sludge on sludge. Although the sludge contained considerable total soaking period in water, compared to 7% aggregate stability soil amendment. Water treatment sludges were obtained from soil properties that influence utilization of the sludge as a soil. The major fraction of the sludge, the coarse clay, was stability of dried sludge was above 90% after a 24 hours suggested that the sludge was highly plastic and that CEC of the sludge was reduced by blockage of cation the sludge. Adsorption of Zn+2 decreased from 19.7 to 17.7 They were mostly coagulated with organic polymers. This study indicated that the sludge can improve soil two orders of magnitudes from 1.4 x 10-4 to 1. I X 10-2 CM / ug / g when the sludge was amended from 0 to 10%. Total water treatment apparently increased nitrogen content of the water utilities along the Neches Rivet- near Beaumont, Texas. |
