Application of ultrafiltration membrane technology in environmental protection projects and sewage treatment

Application of ultrafiltration membrane technology in drinking water treatment

With the continuous advancement of the urbanization process, the urban population has become more and more concentrated, urban space resources and domestic water supply are gradually becoming one of the main reasons for restricting urban development. With the continuous increase of the urban population, the daily water consumption of the city continues to increase, and the daily waste water volume of the city also shows a continuous growth trend. Therefore, how to improve the utilization rate of urban water resources and reduce the pollution degree of waste and drainage has become the primary problem to be solved urgently. In addition, freshwater resources are extremely scarce and people's demand for water purity is getting higher and higher. It is necessary to require that the content of harmful substances in water resources, that is, impurities, be lower, which puts forward higher requirements for sewage purification and treatment technology. Ultrafiltration membrane technology has typical physicochemical and separation characteristics, high temperature resistance and chemical resistance, and stable pH. Therefore, it has unique application advantages in urban drinking water treatment, which can effectively remove organic substances, suspended particles and harmful substances in drinking water, and further ensure the safety of urban drinking water.

Application of ultrafiltration membrane technology in seawater desalination

The world's freshwater resources are very scarce, but the water resources cover about 71% of the earth's total area, that is, the world's unusable seawater resources are very rich. Therefore, desalination is an important measure to solve the shortage of human freshwater resources. The process of seawater desalination is a complex and long-term process. It is a long-term exploration subject to purify seawater resources that cannot be directly used into freshwater resources that can be directly consumed. With the rapid development of science and technology, seawater desalination technology has gradually matured and improved. For example, the use of electro-osmosis technology can achieve one-time desalination of seawater, but the energy consumption of seawater desalination is extremely large. Ultrafiltration membrane technology has strong separation characteristics, which can effectively control the reverse osmosis problem in the process of seawater desalination, thereby improving the efficiency of seawater desalination and reducing the energy consumption of seawater desalination. Therefore, ultrafiltration membrane technology has broad application prospects in future seawater desalination treatment.

Application of Ultrafiltration Membrane Technology in Domestic Sewage

With the continuous deepening of the urbanization process, the daily discharge of domestic sewage in cities has increased sharply. How to reuse urban domestic sewage is an urgent problem to be solved. As we all know, urban sewage is not only a huge amount of discharge, but also rich in fatty substances, organic matter and a large number of pathogenic microorganisms in the water body, which brings a serious threat to the surrounding ecological environment and the health of residents. If a large amount of domestic sewage is directly discharged into the ecological environment, it will seriously pollute the ecological environment around the city, so it must be discharged after sewage treatment. Ultrafiltration membrane technology has strong physicochemical and separation characteristics, and can effectively separate organic substances and bacteria in water. The ultrafiltration membrane technology is used to filter the total phosphorus, total nitrogen, chloride ions, chemical oxygen demand, total dissolved ions, etc. in the urban domestic water, so that they all meet the basic standards of urban water.
