Determining Biochemical Oxygen Demand in Organic Waste Water (.pdf)
Strongly loaded organic industrial waste water, i.e. from sugar- or paper-factories, need to be pre-treated before determining the BOD value. Because of the very high content of organic material in the sample, there is a disparity between the nutrients ratio (C:N:P). The lack of nitrogen (N
Organoclays Trap Incalcitrant Metals and Organic Compounds in Sediments Simultaneously (.pdf)
