“…Tests designed to collect data necessary to develop mathematical models for changes in TP content and COD as a function of tested variables were conducted using a five‐level four‐variable CCRD. A graphic representation of the simplest rotatable design for two tested variables is shown in Figure 2 [39, 42]. However, for four tested variables, α = 2 [42].…”
