How to Choose Filter Media and Filter Aids for Wave-Making Equipment in Water Parks

How does one go about selecting filter media selection and filter aids for wave-making equipment in water parks? Today, Guangzhou Lanchao provides detailed answers to this common query. We all understand that filtration is a crucial step in purification, and the choice of filter media directly impacts the clarity of the filtered fat and the ease of cake unloading. Therefore, it’s essential to pay special attention when choosing filter media selection and filter aids. Let’s delve into the details below.

In reality, most filter media used in the oil industry are woven materials. Commonly utilised are 20 yarn 5-8 strands of canvas, twill, and ordinary white muslin, along with other cotton fabrics. Chemical fibre products such as 130#, 240#, 260#, 261# polyester filter cloth and 828# nylon filter cloth are also frequently used. Those with more warp and weft strands are employed for crude oil filtration, while those with fewer strands are used for essential oil filtration. For high-demand filtration, a layer of white muslin or flannel is often placed over the coarse filter cloth. Additionally, stainless steel wire woven filter screens are commonly used, with 30-40 holes/cm screens for crude oil filtration and 140-180 holes/cm screens for decolorising oil filtration.

For suspensions containing more colloidal particles, adding filter aids can effectively increase the filtration rate. This is particularly significant for some water park equipment where technological limitations prevent the use of increased temperature filtration in the suspension system. The application of filter aids becomes crucial. If you wish to use leaching oil to produce edible phospholipids, diatomaceous earth must be added as a filter aid. In dewaxing and fractionation, which must be filtered at lower temperatures, the role of the filter aid is even more pronounced.
