What is PES hollow fiber filter:

PES hollow fiber filter is a polyethersulfone membrane filter composed of multiple groups of parallel hollow fiber membranes and generally be divided into ultrafiltration (1-1000kD) and microfiltration (0.1-1.0um). The hollow fiber filters we do is made of modified PES and widely used in beer clarification filtration and Purification & Concentration of biopharm filtration.

What is beer clarification filtration:

After beer has been fermented and aged, it is bulk filtered for clarification and stabilization. Beer clarification is a crucial but difficult stage of the brewing process. It is used to reduce particles in the finished product which may be caused by low temperature reactions. Clarification filtration is crucial to ensure the main quality features for beer as product occurrence, taste stability, brilliance, haze and shelf life.

What is diatomaceous earth (DE)? Why DE-free filtration is required？

Diatomaceous Earth (DE) is a natural mineral powder formed by tiny diatom fossils. It has long been widely used in beer filtration to remove suspended particles, yeast and other impurities to make beer clearer and more transparent.

Disadvantages of DE filtration：

• Waste disposal: DE will generate a large amount of waste after use. The disposal cost of these wastes is high and there is a potential risk of environmental pollution.
• Health risks: Diatomaceous earth produces dust during drying and handling. If not handled properly, it is harmful to human health after inhalation and may cause respiratory problems.
• Troublesome cleaning: Diatomaceous earth filters need to be frequently replaced and cleaned, which increases labor costs and operational complexity.
• Environmental Trend；

Due to the above disadvantages, many breweries are turning to DE-free filtration technology to achieve a more environmentally friendly production method. Diatomaceous earth-free filtration using hollow fiber membrane technology can achieve similar filtration accuracy as DE, but without the waste problem of DE. Membrane filtration can remove yeast and microorganisms through cross-flow technology, and significantly reduce waste and energy consumption, andi is now becoming the choice of more and more beer manufacturers.
