    Factors affecting filter press performance

    Time: 2023-08-08 Source: Author: hlsolidscontrol
    Filter press is a kind of equipment used for solid-liquid separation, which is widely used in sewage treatment, mining, chemical industry and other fields. Its treatment performance depends on several factors, including the viscosity of the slurry, the filtration cycle time and the moisture content of the filter cake after the filter press is completed.

    The viscosity of the mud refers to the mutual attraction between the molecules inside the liquid. The higher the viscosity, the stronger the mutual attraction between the molecules, making the liquid more viscous. In the filter press process, the viscosity of the mud is an important parameter, which affects the filtration speed and efficiency. According to the information provided, when the mud viscosity is small, the filtration is relatively easy, and a filtration cycle time is 60 minutes; while when the mud viscosity is high, the filtration is difficult, and a filtration cycle time is 90 minutes. This shows that the viscosity of the mud directly affects the processing speed and effect of the filter press.

    Filtration cycle time is the time elapsed from the start of one filter press cycle to the start of the next cycle. According to the information provided, the filtration cycle times at different slurry viscosities were 60 minutes and 90 minutes respectively. This means that in the case of higher viscosity, the filter press takes longer to complete a complete filtration cycle, thereby ensuring the effect of solid-liquid separation.

    The moisture content of the filter cake refers to the percentage of moisture contained in the solid filter cake after the press filtration is completed. The moisture content of the filter cake is about 30%. Actual filter cake moisture content may vary due to specific slurry properties, operating conditions, and filter press design. The water content of the filter cake is an important index to measure the effect of the filter press. A lower water content means that the solid matter is better separated, thereby improving the treatment efficiency.
