Biological treatment of wastewater from an integrated oil refinery, containing hazardous contaminants, was studied in an on site pilot plant. The wastewate... N Galil,M Rebhun,Y Brayer - 《Water Science & Technology》 被引量: 28发表: 1988年 Removal of Benzene from Oil Refinery Wastewater Treat...
The main problem of the biological treatment of coal gasification wastewater is that it is not effective in removing the refractory organics and NH3, and has low running stability. Aerobic(O)-anoxic(A)-aerobic(O)biological process is put forward for the wastewater second treatment. The experiment...
Emissions of NO from soil are seen as a direct indicator of microbiological activity in the soil, which in turn can suggest the presence, absence, and/or concentration of different contaminants in soil. For example, laboratory measurements of NO emissions from uncontaminated soil and soil that has...

cepa meristematic root cells in the assessment of the genotoxicity of wastewater samples from sewage and industrial effluents, being that the latter was influenced by discharges of textile and paper mill. El-Shahaby et al. [51] applied the CA and MN test in A. cepa to evaluate the ...
These methods are useful tools for assessing the impact of chemicals on biological wastewater treatment processes. They are also well suited for evaluating the treatability potential of individual wastes. However, varying results are often reported when using municipal or industrial activated sludge ...
PFAS testing demands a high level of analytical sensitivity to ensure accuracy. For example, the EPA’s initial health advisory for PFAS (70 PPT) was more than 100 timeslowerthan the Maximum Contaminant Levels for more common water contaminants like arsenic (10000 PPT) and nitrate (1000000 PPT...
Leaching testsare frequently used to assess the potential risk of a waste to release organic andinorganic contaminantsinto the environment. Several leaching protocols have been developed with each differing in terms ofleaching solutionused, liquid-to-solid ratio, contact time, number of extractions and...
Contaminant and fluid are continually fed into the circulating flow to maintain a constant flow of contaminants into the test filter, making up for the particles lost through being trapped in the filter, and for the fluid removed from the system with samples, to ensure a consistent challenge to...
