First, Measure the pH of the water with a pH meter. It was found that the water has a pH value changes from 12.68 as compared to standard values which 6.86-water industry, which provides the largest range of pH, pH 9.0 and the smallest range, so that through the benchmark 5.5.The second stage. Measurement of turbidity meter Turbidity water with water is found, change the value from which the Turbidity is 562.9-17.8, compared with the industry standard of water Turbidity ranges, most everything that passed the benchmark.The third stage. Measure the Absorbance value of the water with a spectrophotometer, it was found that the water is changed, the value is-0.018 0.790 Absorbance from but does not have a standard industrial water Absorbance values appear.The four stages of labor DO with DO with water meter found that changing the value from 1.4 mg/L DO a 6.3 mg/L, which is the standard value when compared to the water industry, which produces more than it should DO, or 5-8 mg/L.
