【Summary】Microbial life activities and substance metabolism are closely related to pH value. Most microorganisms are adapted to a pH range of 4.5 to 9, while the optimal pH range is 6.5 to 7.5. When the pH is lower than 6.5, fungi begin to compete with bacteria, and when the pH is up to 4.5, fungi will be completely dominant in the biochemical tank, which seriously affects the sedimentation result of sludge. When the pH exceeds 9, the metabolic rate of microorganisms will be hindered. Different microorganisms have different pH range requirements. In aerobic biological treatment, pH can vary between 6.5 and 8.5; In anaerobic biological treatment, the pH of microorganisms is relatively strict, and the pH should be between 6.7 and 7.4.

The amount of disinfectant required varies according to the water source and water quality. Generally, 0.5mg to 4.5mg of effective chlorine is required per liter of water. Under normal circumstances, the amount of disinfectant used in surface water is larger than that in underground water...
