- W2994867029 abstract "BOD value is a test parameter in a laboratory that depends on time and temperature. The reaction rate of BOD value for time is defined as the deoxygenation coefficient (k) which depends on the concentration of organic matter in the sample and the relation described in the Streeter-Phelps equation, kT = k20 θ(T-20). In the equation, the value of the temperature coefficient must be determined so that the required incubation time can be calculated for the incubation temperature that is different from the standard method. Various literatures mention the value of the temperature coefficient in the range of numbers 1.03 - 1.09. If there are certain wastewater with low organic concentration matter the temperature coefficient is unknown, the number 1.047 will be used at the testing temperature in the laboratory, 27 - 29 °C. This study aims to analyze whether the coefficient value can be applied to specific wastewater such as faecal sludge waste in various concentration, low to high. The thing to do is to compare the determination of the standard method BOD value by determining BOD at another temperature in the incubation time span estimated using the temperature coefficient value of 1.047. It will be known whether the determination of BOD value can be done by incubation at laboratory temperature and shorter time will have a higher deoxynegation coefficient value when compared to the standard method at temperature 20 °C." @default.
