Creped Filter Papers with large filtering area

Short Description:

Creped filter papers are made of wooden pulp; mostly used for the rapid filtration of relatively coarse precipitates; because of their creped structure they provide a larger filtration area than smooth filter papers. Grades with a wet burst resistance > 30 kPa are referred to as wet-strengthened and are therefore suitable for pressure or vacuum filtration.
For example: matching with frying oil filter. It is used for frying oil filtering of KFC and McDonald’s.

Great Wall supplies you with a broad range of filter papers for myriad filtration tasks and supports you in solving all your filtration challenges.

    Creped Filter Papers Applications:

    Great Wall filter paper includes grades suitable for general coarse filtration, fine filtration, and retention of specified particle sizes during the clarification of various liquids. We also offer grades that are used as a septum to hold filter aids in a plate and frame filter presses or other filtration configurations, to remove low levels of particulate, and many other applications.
    Such as: production of alcoholic, soft drink, and fruit juice beverages, food processing of syrups, cooking oils, and shortenings, metal finishing and other chemical processes, refinement and separation of petroleum oils and waxes.
    Please refer to the application guide for additional information.

    Creped Filter Papers Features

    •Uniformly creped surface with cellulose fiber pre-coat for a larger, more effective surface area.
    •Increased surface area with a higher flow rate than standard filters.
    •High flow rates can be maintained while effectively filtering, so filtration of high viscosity or high particle concentration fluids can be performed.

    How Do Filter Papers Work?

    Filter papers are actually depth filters. Various parameters influence their effectiveness: Mechanical particulate retention, absorption, pH, surface properties, thickness and strength of the filter paper as well as the shape, density and quantity of particles to be retained. The precipitates deposited on the filter form a “cake layer”, which – depending on its density – increasingly affects the progress of a filtration run and decisively affects the retention capability. For this reason, it is essential to select the right filter paper to ensure effective filtration. This choice also depends on the filtration method to be used, among other factors. In addition, the amount and properties of the medium to be filtered, the size of the particulate solids to be removed and the required degree of clarification are all decisive in making the right choice.

    Great Wall pays particular attention to continuous in-process quality control; additionally, regular checks and exact analyses of raw material and of each individual finished product assure constant high quality and product uniformity.
