Beer Filtration

Breweries utilize a great deal of filtration to remove bacteria and microbes prior to bottling, but also to capture DE released from filter sheets, allow clean air into holding tanks, provide clean wash water to clean bottles, and to protect the membrane filters. Graver can provide a wide selection of filters to meet the application needs as well as suit a desired price point for the customer. In particular, Graver products can achieve:

Particulate removal from incoming water streams
Provide cyst reduction from incoming water
Clarify /trap DE from filter sheets
Prevent microorganisms from entering storage tanks
Removal of particulate and microbes from bottle rinse water
Microbial stabilization prior to bottling
Deionization of incoming water streams
