BEHAVIOR OF ADSORPTION HEAT UNDER DEODORIZATION USING ELECTROLYTICALLY TREATED SLUDGE

Adsorption of Selenite on Heat Treated Sea Nodule Residue

The present study was carried out to investigate the adsorption characteristics of sea nodule residue (SNR) heated at 400°C towards aqueous selenite. Physico-chemical characterization revealed that the leached residue was a complex mixture of oxides of mainly manganese and iron along with MnCO3. Adsorption studies were carried out at varying the pH, selenite ion concentration, SNR dosage and in...

Fatigue Behavior of Heat Treated 30MSV 6 Vanadium Micro alloyed Steel

‌‌‌Fatigue behavior of a vanadium microalloy steel has been studied in this research. Here, microstructure constituents were considered which essentially are dependent on the heat treatment conditions. The results of high cycle fatigue tests revealed that heat treatment procedure and cooling rates have significant effects on fatigue properties. Optimal heat treatment cycle of the microalloyed s...

Adsorption of Cd(II) by Dried Activated Sludge

Heat inactivation of poliovirus in wastewater sludge.

The effect of raw and anaerobically digested sludge on heat inactivation of poliovirus was investigated. Raw sludge was found to be very protective of poliovirus plaque-forming ability at all temperatures studied, but digested sludge had variable effects that were highly dependent upon the experimental conditions. In low concentrations and at relatively low inactivation temperatures, digested s...

Adsorption of heavy metals by EPS of activated sludge.

Extracellular polymeric substances (EPSs) were extracted by high-speed centrifugation at 20,000 G for 30 min from an activated sludge treating municipal wastewater. Each gram of sludge, as measured in volatile suspended solids (VSS), contained 7.3 mg of EPS, including 6.5 mg of protein (EPSp) and 0.8 mg of carbohydrate (EPSc). The EPSp had a mean MW of 2.0 x 105; about 18% of EPSp had MW over 5...
