Why is the microbial hazard of circulating water more serious than that of straight water
The temperature, pH and nutrient composition of the circulating water are all conducive to the propagation of microorganisms, and sufficient sunlight on the cooling tower is an ideal place for algae to grow. The direct flow system has no air
The evaporating process of cooling involves only microorganisms brought in with the current, and the direct flow system provides less favorable conditions for microbial reproduction than circulating water (suitable temperature, pH and nutrients)
Most importantly, the sewage discharged from the circulating water is returned to the system for circulation, causing a vicious cycle, and the microorganisms that multiply in the DC water are immediately removed. So circulating water
The microbial damage is much more serious than that of straight water, and the higher the concentration ratio, the more serious. Such as some circulating water systems, the total number of bacteria in the supplementary water is only 100~1000, but in the circulating water
The total number of bacteria can be as high as 100, 000 or more, which creates a microbial hazard in the system.
