How to judge whether the water quality is secondary water supply

How to judge whether the water quality is secondary water supply? In recent years, most high-rise residential areas have adopted secondary water supply, and the secondary water supply also has drinking water safety problems to a certain extent. The water source usually provided by the main network is called the primary water supply, while the water source flowing from the centralized water tank through the water supply system is called the secondary water supply. The primary water supply is strictly disinfected in accordance with the requirements, and the secondary water supply is pressurized through the pipeline. After storage, there may be a large number of microorganisms in the water. At this time, it will have a certain impact on water safety, so it is necessary to install it in most environments. The secondary water supply water quality online monitoring system is used to ensure the water quality, so do you know how to judge whether the water quality is secondary water supply? How to judge whether the water quality is secondary water supply There are two main ways to judge whether the water quality is secondary water supply. One is to open the pipeline valve inside the corridor, as long as the floor is not too high, it can basically be judged as a municipal direct water supply source. Then check upwards layer by layer. If there is a sudden loss of a pipe in a certain layer, then pressurized water is used on this layer, which is what we call secondary water supply. Another method is to judge based on experience. Most of the municipal water supply will not exceed the height of the six-story building, that is, the building height below the six-story building can basically be judged as a primary water supply, and the upper floors, due to water If the pressure is not enough, then the secondary water supply is usually used, but this method is not particularly accurate, because a part of the tap water may be equipped with a pressure reducing valve to control the pressure of the water source, and this situation is quite special, for example, in a certain location In the case of low municipal water supply pressure and low water demand, pressurized water can be supplied through tap water tanks. The above are the two methods for judging whether the water quality is secondary water supply. If the secondary water supply without disinfection is used for a long time, it will definitely have some impact on our lives. Therefore, in most secondary water supply industries, it is generally necessary to adopt Secondary water supply online monitoring system to analyze water quality in real time.
