A high efficient aerobic denitrifying bacterium (G2) capable of rapid removal of NO3 and NO2 was isolated from activated sludge. The purpose of this work was to study the characteristics, pH and temperature effects of the isolated bacterium. The morphology of the isolated aerobic denitrifier G2 was a short bacillus, with average size of (0.3~0.6) mumtimes(1.4~3.0) mum. According to the 16S rDNA sequencing...
Magnesium-ammonium-phosphate precipitation method (MAP) is a newly-developed technique to remove ammonia nitrogen from wastewater. In this study, MAP method has been studied by using MgCl2-6H2O and Na2HPO4-12H2O as precipitators for treating highly concentrated ammonia nitrogen wastewater. The effect of pH value, formulas of precipitation and precipitator ratio on MAP precipitation efficiency has...
The influence of co-existing chloride, sulfate, pH, and temperature to defluoridation of groundwater using nanofiltration membrane and membrane fouling were studied. The results show that nanofiltration has retention effect to all co-existing ions. When feed fluoride concentration was less than 6 mg/L, the fluoride concentration in permeated water was less than 1.2 mg/L which could reach the drinking...
The adsorption process of heavy metal ions from aqueous solution by konjac glucomannan based resin (KGR) was investigated. The adsorption capacity is found to be dependent on the pH of the solution, the effects of adsorption time, the dosage of different adsorbents, the initial concentration of heavy metal ion and temperature. Moreover, the adsorption capacity increases with the increasing degree...
