High-Efficiency Fast Filtration (DA863)

The DA863 filter media, a creative filter material, is designed based on the theoretical physical principle: Non-linear science branch structure theory. The most predominant characteristics is its dissymmetrical and branch structure.

The DA863 has the advantages of high precision and high intercepting capacity of fibre medium and high backwashing cleanliness and low water consumption of granular filter media. The porosity distribution of the filter bed formed by the DA863 filter media is close to an ideal filter media.

Quality of filtrate is mainly determined by the type of filter media. The following main four criteria are used to evaluate quality of a filtration technology: 1) porosity; 2) filtration velocity; 3) precision; 4) pollutant intercepting capacity. An ideal filtering technology should integrate these four points.

Dissymmetrical fractal structure is a mystical structure, which commonly exists in nature. The DA863 adaptive filter media is ometic fibrous filter media? With dissymmetrical fractal structure. This filter media has high intercepting capability and good backwashing performance. The homogeneity of porosity on the cross-sectional surface and the proper porosity gradient on the longitudinal section surface ensure high-speed and high-precision filtration at the same time, leading to an ideal adaptive filter bed structure with low density in the upper part and high density in the lower part.

The filter media with branch structure has the following advantages:
A) High Porosity; B) Fast filtration speed; C) High filtration precision & Low resistance; D) High pollutant-intercepting capacity
