Learn from the advanced practices of the *Brothers section; there are prizes for correct answers – every response earns a reward, allowing us to grow and mature through these Q&A sessions. Short answer: What is the impact of a low vacuum level on the system? (1) The temperature of the water after flash evaporation is high, which raises the temperature of the water entering the sedimentation tank; this in turn affects the efficiency of flocculant precipitation and leads to a deterioration in water quality. (2) Acidic gases in water cannot be completely removed, affecting the water quality of the system. (3) The amount of flash vapor decreases, resulting in less heat being carried away and an increased thermal load on the system. (4) An increase in the amount of black water entering the sedimentation tank leads to a deterioration in the water quality of the system.
