Post fermentation removal of sediment and yeast is typically done using high solids removal technology such as lenticulars, filter press or even microfiltration crossflow. Any remaining sediment and yeast can effectively be removed in the filtration step prior to the bottling process. In types of beer, haze often caused by protein complexes can develop and these can be addressed using a charged media such as glass.

Water filters containing ion exchange resins and/or activated carbon can remove PFAS chemicals.

Many MetSorb(R) adsorbents will remove heavy metals from water and wastewater. Please view our product pages for more information.

PFAS can be removed with adsorbents and ion exchange resins like MetSorb(R) PFX.

Many MetSorb(R) adsorbents will remove lead and other heavy metals from water. Please view our product pages for more information.

Always check labeling for certification of contaminant removal from filter products.

Several essential applications for filters. Tank vent or fermentation feed air filters, the choice of which depends upon the specific method being used in the fermentation process, ensure that particles and microbes do not enter the process through air sources. These filters should utilize a hydrophobic membrane such as PTFE and have claims for sterility. A second area is to ensure that all fluids in the process are microbial-free, so filtration using a 0.2 micron hydrophilic membrane filter that is rated as sterilizing grade is commonly used. This would apply to water, nutrient broths or any liquid additive essential to the process.

Most filters are synthetic materials and thus are not designed to be cleaned and reused. Filters are generally intended to be used until plugged, which can be defined by loss of flow or a terminal pressure drop increase.

In order to maximize the life of reverse osmosis membranes, it is highly recommended to use a filter in front of the membrane with the goals of reducing the risk of fouling the membrane. Membrane fouling is the main cause of permeate flux decline and loss of product quality in reverse osmosis systems. Silt Density Index or SDI (ASTM standard test method D 4189-82), is the empirical test developed for measuring the potential rate of fouling of RO membranes

Aeration helps remove dissolved gasses and� oxidizes dissolved metals, including iron and hydrogen sulfide, as well as break-down organic molecules and volatile organic chemicals (VOCs)
