Clarity (C): Clarity is an indicator that reflects the suspension or turbidity in a liquid.It can be represented by measuring the extent to which light passes through the liquid.Clarity can be calculated using the following equation: C = (I₀ -I) / I₀ (1) Where C represents clarity, I₀ is the intensity of incident light, and I is the intensity of light after passing through the sample.By measuring the intensities of these two light sources, clarity can be calculated.
Treatment Groups (G): In the experiment, the same batch of fermentation liquid is divided into three groups, each subjected to different treatment methods.These groups can be represented as G, namely Traditional Filtration Group (G₁), Centrifugation Group (G₂), and Soil-Free Filtration Group (G₃).Time (t): The experiment is conducted within a certain time frame, and time can be considered as an independent variable to observe how clarity changes over time.Time can be denoted as t.
Number of Measurements (n): To ensure result accuracy, clarity for each treatment group can be measured multiple times.The number of measurements can be represented as n.
Therefore, the following equations can be used to represent the clarity of each treatment group at different time points in the experiment: C (G₁, t₁), C(G₁, t₂), ..., C(G₁, tₙ) C(G₂, t₁), C(G₂, t₂), ..., C(G₂, tₙ) C(G₃, t₁), C(G₃, t₂), ..., C(G₃, tₙ) These clarity data points, measured using a high-precision clarity testing instrument, will be used for subsequent graphical representation and data analysis to clearly demonstrate the dynamic changes in clarity among the treatment groups, thereby quantitatively comparing the differences in clarity between traditional filtration methods, centrifugation, and soil-free filtration technology.
