1. The combined process characteristics of pvdf ultrafiltration membrane and short process.
a. The process integrates water purification projects such as inclined plate sedimentation tank, sedimentation, pvdf ultrafiltration membrane, concentrated water recovery, and sludge concentration.
b. It can flexibly use the working nozzle of the original process flow of the water plant to save energy consumption.
c. The idle siphon filter can be used as emergency treatment equipment for future water pollution.
d. The combined process of ro uf membrane and short process is applied to the renovation and transformation of water plants, without the need to build sludge thickening equipment, saving floor space and saving total capital construction costs.
2. Development process of pvdf ultrafiltration membrane and short process combination.
The pvdf ultrafiltration membrane
technology provides a new idea for the renewal and transformation of water plants, and its application prospects are broad. However, he also emphasized that in-depth research is needed during the entire process of the technology's re-operation. In the short-flow technology, before entering the ro uf membrane, only Geshan is used to isolate the floating matter in the water, which can save the self-cleaning filter device and achieve the purpose of environmental protection and energy saving. At the same time, the potential damage to the application of the ultrafiltration membrane by aquatic organisms is also increased. How to solve the problem of potential membrane environmental pollution is one of the future research directions of authoritative experts.
In the current application of pvdf ultrafiltration membrane and short-flow combined process, it is necessary to further study the treatment of dissolved organic chemical pollutants.
The customer clearly proposed the application standard of uf membrane use and short-flow combination technology. Experts suggest that uf membrane use and short-flow combination technology are technical measures clearly proposed by the current water plant to improve the microbiological safety factor of the effluent water body. It is suitable for Renovation of most water plants.
It is a very good technical work experience, but all technologies are not omnipotent. When the combined technology of ultrafiltration membrane and short process is applied in other water plants, the solubility of organic chemical pollutants in the water must be considered, and the corresponding pretreatment work must be improved.
