Adsorption filtration method is a typical oily wastewater treatment method for low strength wastewater size of less than 1 Ol} m of oil droplets, which removes better (Takahashi et a 1 magnetite media use, 1979). Surface properties of water filtration media help us to understand the mechanism of oily wastewater. wettability of the surface properties of the filter media is a very important role in magnetite media in general, if the oil on the filter material good wetting, the filter effects; otherwise poor filtration This paper by measuring several common wetting contact angle of water filter to study the amphiphilic nature of the differences, in order to select the appropriate treatment of oil. filter wastewater to provide a theoretical reference. water filter particle size is much larger than the average diameter of the solid powder, can be successfully used in water treatment W ashbum equation wettability study results mainly depends on the filter surface weight reproducibility. Figure 2 is 0. 45 ~ 0 90mm magnetite media wetted with deionized straight section 5 repeated experiments of water. calculated the average slope of the line 5 and the error range of 0 362 1Q 027 preliminary that experimental reproducibility better quality magnetite media, described in the experiment, the media particle size range, the W ashbum equation used in the test method of wettability of water filter feasible, accurate results reliable results for each of the following average of five replicate experiments. Figure 5 is three kinds 0 45 ~ 0 90 SFM Atlas mm filter particles. The figure shows the walnut shell surface is rough, but the arrangement are more rules, each of the sex is better, its surface developed porosity, large specific surface area and pore volume. magnetite rough surface, irregular, and the surface distribution of the grains and the wafer anisotropic obvious magnetite media, in addition, the surface there are certain porosity ceramic sand surface is smooth, but irregular, but also the distribution of grain, also showed anisotropic characteristics; Further surface area and pore volume is less than the walnut shell and magnetite clearly map and SFM. wetting process basically. In general, the wettability of liquid, the Bad and the filter surface roughness of the wetting process. Since most magnetite surface roughness, walnut shells, followed by relatively ceramic sand smooth, so the liquid can wet, the wettability of magnetite and ceramic sand preferably slightly worse. That is magnetite, ceramic sand surface contains a variety of metal oxides, are high-energy surface, the surface tension large water-wetting surface tension smaller cyclohexane can also be very good wetting amphiphilic than small; the walnut shell surface organic functional group is mainly for low-energy surface, its larger surface tension The water wet poor, while the smaller surface tension of cyclohexane good wetting, so amphiphilic ratio. magnetite filter manufacturers, Xianyang magnetite media, the German source water from Henan German source Water Limited.
