Paper pulp compressed into pads is used in pressure filters for beverage clarification. After becoming dirty, as evidenced by decrease in the rate of flow, the paper may be repuiped, water-washed and reformed into pads. Although this involves considerable work, excellent clarity and high flowrates are obtained. The impurities do not form a cake as such, but penetrate into the pad and can only be removed by repulping and washing the pad.

Particles play a key role in many processes. In chemical engineering, catalytic reactors utilize catalysts, which are particles on the surface of which reactions occm. Major processing industries (plastic materials, ceramics, cement, paper, inks, etc.) operate based on their corresponding particulate materials. The same applies for the food processing industries also (powders, grains, beverage clarification, etc.). Lastly, in environmental studies, we may mention water treatment, gas scmbbing, incineration, and soil treatment processes, or indeed the problems of sedimentation in rivers, ports, and on beaches, all of which involve directly particnlate media. 

Papain is a cysteine protease isolated from the latex of the immature fruit and leaves of the plant Carica papaya. It consists of a single 23.4 kDa, 212 amino acid polypeptide, and the purified enzyme exhibits broad proteolytic activity. Although it can be used as a debriding agent, it is also used for a variety of other industrial processes, including meat tenderizing and for the clarification of beverages. 

Food and beverage processing represents an expanding area for process-scale microfiltration. Already in place are clarification systems for wine and beer, sugar, and gelatin, replacing existing practices such as diatomaceous earth filtration. Less attractive economically are miscellaneous waste treatment applications, for which microfiltration is often a sophisticated but expensive alternative.

The more acidic the beverage, the better is the clarification effect with a given level of fining agent. The result is also temperature-dependent. For successful fining, the temperature of the juice should not normally be less than 12°C. 

Inorganic membranes have also been used in the clarification of other fermented alcoholic beverages such as beer and vinegar in recent years. Two important applications of membrane filtration for beer production are the removal of bacterias and beer recovery from the so-called tank bottoms. They are treated in the following.

Membrane-based separation processes are recognized as environmentally friendly alternatives to conventional separation techniques such as distillation or extraction. The field of large-scale applications covers the range of drinking water processing, potable water production, waste-water treatment, application in the food and pharmaceutical industries, recovery of aroma and active substances as well as sterile filtration of pharmaceuticals and clarification of beverages. 

In the past ten to fifteen years or so, the applications sphere of cross-flow filtration has been extended to include microfiltration (MF) which primarily deals with the filtration of colloidal or particulate suspensions with size ranging from 0.02 to about 10 microns. Microfiltration applications are rapidly developing and range from sterile water production to clarification of beverages and fermentation products and concentration of cell mass, yeast, E-coli and other media in biotechnology related applications.
