We are thus led to the conclusion that dilution multiple of F1=1/(CODX0.

According to the relation of BOD 5 and TOC in refinery effluent,the dilution multiple of BOD 5 can be estimated and then used for measurement in the computation model.

Preparation of inoculation liquid and certain dilution multiple were pivotal step for determination biochemical oxygen demand, the paper gave viable method for preparation of inoculation liquid,summarized calculation method of dilution multiple.

Simulated samples of urinal wastewater prepared at the laboratory are treated with different dilution ratios by a commercially available reverse osmosis module.

And these factors such as sunshine,diluent,dilution,depressor,reagent quality and titration termination could not ignored during the determination of BOD5.

[Objective] The present study aimed to confirm the best reaction time and wine dilution of the ABTS·+ method.

According to the indispensable conditions of measuring BOD 5,the method theorically deducted can draw the approximate range of water sample dilution times The measurements of several kind of industrial wastewater proves that it is a convenient and feasible metho

Which of the light standard of judging ages and the determination of maximal extension rate and the influence on moisture content in study plot were studied.

This paper introduced several methods for chromaticity measurement of wastewater from the pulp and paper industry,in which platinum-cobalt methods and dilution multiple methods were included.
