  • Publication number: 20250074804
    Abstract: The method for treating wastewater includes a first flocculation-and-sedimentation process and a second flocculation-and-sedimentation process, wherein the first flocculation-and-sedimentation process include: passing wastewater through a first flocculation reaction tank; passing the first treated water through a third flocculation reaction tank; passing the third treated water through a fourth flocculation reaction tank; and passing the fourth treated water through a first sedimentation tank to generate fifth treated water and sludge, and the second flocculation-and-sedimentation process include: passing the fifth treated water through a fifth flocculation reaction tank to generate sixth treated water; passing the sixth treated water through a sixth flocculation reaction tank to generate sixth treated water; passing the sixth treated water through a seventh flocculation reaction tank to generate eighth treated water; and passing the eighth treated water through a second sedimentation tank to generate ninth t

  • Patent number: 7531130
    Abstract: The present invention relates to an anti-galling alloy with finely dispersed precipitates, more particularly to an anti-galling alloy comprising Ni, Cr, Sn, Bi, Mo, Fe, Si and Te, in which the matrix has a fine dendritic structure and the Bi-rich precipitates are finely dispersed between the dendritic structure, so that the anti-galling properties are significantly improved, while physicochemical properties such as corrosion resistance and hardness are not deteriorated. The anti-galling alloy of the present invention will greatly contribute to the improvement in life cycle and mechanical precision of a variety of wet machinery parts such as rotor, shaft, valve and mechanical sealing.
