How to unload the membrane elements of the factory's buried sewage treatment equipment? Author: Today, the rapid industrial development, so that the factory continued development and growth, expansion of the factory is bound to increase the amount of sewage discharge. Many factories have invested a lot of money and have not found a suitable sewage treatment plan. How to solve the factory sewage has become the heart disease of this industry. There are many sewage treatment processes in the factory. Natural ecological treatment, biological treatment, and chemical treatment are all applied. Various processes have their advantages and limitations. They should be selected according to the characteristics of the influent water quality, treatment and discharge requirements, and comprehensive consideration of economic and management factors. The best factory sewage treatment equipment and technology, and pay attention to the combined use of different factory sewage treatment processes. For example, the main structure can be treated with anaerobic and aerobic treatment, supplemented by natural ecological treatment, which can not only ensure the quality of effluent water, but also save energy and reduce operating costs. An important component in the factory buried sewage treatment equipment is the membrane element. The membrane element determines the water treatment effect. However, the membrane element needs to be cleaned after a period of use, and needs to be replaced when it reaches the service life, which needs to be unloaded. Membrane elements, how to unload the membrane elements of the factory's buried sewage treatment equipment? 1. Push out the membrane elements one by one from the water inlet end of the pressure vessel. The element and the membrane element should be leveled to prevent damage to the central tube connector from being damaged by gravity. The membrane element can be properly rotated to separate the membrane element from the tube connector. 2. Only hit the concentrated water side plate end of the membrane shell, turn on or jog the high-pressure feed water pump, and push out each membrane element one by one under the action of the feed water pressure. In the system, the diameter of the membrane shell is small, the length of the membrane shell is short, and the unloading resistance is small. The former method can be used, while the latter method is more used instead. 3. Open the front and rear panels of the membrane shell: use a long rod to push out each membrane element one by one from the water supply side to the concentrated water side. If the membrane element is pushed out from the concentrated water side to the feed water side in the opposite direction, the resistance is generally greater than the resistance in the positive direction. The above content is the editor's introduction on how to unload the membrane elements of the factory's buried sewage treatment equipment. I hope it will be helpful to everyone. If the membrane elements are not replaced after their useful life, it will affect the quality of the effluent, so remember to replace the membrane elements regularly .
