Key innovations
The innovation lies in using cheap diatomite to dynamically form films, effectively reducing traditional membrane pollution and water production costs, and combining biological carriers to enhance pollutant removal.
Potential economic benefits
This technology uses cheap diatomite, which significantly reduces membrane pollution treatment costs and overall water production costs. By strengthening pollutant removal, water treatment efficiency is improved and operation and maintenance costs are reduced.
Potential climate benefits
Diatomite dynamic membrane technology can reduce the energy consumption of traditional water treatment processes by improving water treatment efficiency. Reducing the use of chemicals reduces carbon emissions from the production and transportation of related chemicals. Biological diatomite enhances pollutant removal and avoids the need for subsequent advanced treatment with high energy consumption.

Solution details

Membrane technology has the characteristics of good interception effect, but it has problems of membrane pollution and high water production costs. Using the microfiltration characteristics of powdered diatomite and its low price, diatomite dynamic membrane technology was developed. Diatomite forms a dynamic membrane on the support system, which has the accuracy of microfiltration and ensures the turbidity of effluent water. Use diatomite as a carrier for microorganisms to form biological diatomite to enhance the removal of pollutants in water. As a result, a biological diatomite dynamic membrane device, a cross-flow tubular diatomite dynamic membrane device, a biological diatomite dynamic membrane-ultrafiltration reactor and tubular components were developed.
