Advantages:
The use of membrane separation technology only provides the necessary operating pressure for supplying raw water, and only requires running for a long time to flush the filter membrane, with no other processes. At present, there are numerous processes involved in coagulation, precipitation, and filtration water treatment, and the dosage rate cannot be set yet. In such a situation, it is easy to automate the membrane device and achieve unmanned management, while it is not easy to automate conventional processing.
Adopting a filtration membrane water plant, the membrane device occupies a small area, making it easy to reduce the plant area occupied by conventional treatment with the same water production by half. Activated carbon treatment devices can be installed in the remaining areas. Due to the unmanned nature of the filtration membrane water plant, the buildings and supporting facilities where employees reside can be reduced.
The current service life and price of the filter membrane are still unknown, and the total cost is difficult to calculate. However, from the perspective of lower electricity and medication costs for membrane treatment, it has significant advantages over the higher maintenance and management costs of conventional treatment.
Application:
In addition to being used for water treatment, filter membranes can also be used for ultrapure water manufacturing and seawater desalination, generally using reverse osmosis membranes (Nano membranes). In addition, ultrafiltration membranes and microfiltration membranes are generally used for fecal and urinary treatment, urban waterway treatment, various wastewater treatment, etc. In industry, ultrafiltration membranes and microfiltration membranes are commonly used in dairy product manufacturing, semiconductor manufacturing, food manufacturing, paper manufacturing, and pharmaceutical manufacturing.
Filter membranes are used in various industries such as food and beverage, medical and pharmaceutical, municipal water treatment, industrial high-purity water, boiler water replenishment, seawater desalination, electronic industry ultrapure water, wastewater treatment and reuse, material concentration and purification, etc.
Widely used household ultrafiltration water purifiers and ultrafiltration membranes. It can remove large molecules, colloids, proteins, particles, etc. from the solution, and has the characteristics of low operating pressure, high water production, and easy operation.
Application of ultrafiltration in wastewater treatment
It has been applied in the treatment of spray painting wastewater, metal processing wastewater, and food industry wastewater in the automotive manufacturing industry, as well as the recovery of useful substances. Ultrafiltration has good removal characteristics for various colloids in water, so it can be considered to be expanded to the pretreatment of condensate polishing and ion exchange desalination systems.
Application of ultrafiltration membrane in the preparation of raw water for liquor production
Ultrafiltration membrane components are applied in micro beer production workshops. By testing the treatment performance of the membrane device, it is shown that using ultrafiltration membrane for deep purification of raw water for brewing can effectively reduce the concentration of various pollutants in the water, eliminate secondary pollution caused by pipeline networks, and meet the requirements of high-quality raw water for brewing processes
