From DE to Depth Filters: Maximize Flavor & Clarity

From DE to Depth Filters: Filtration 101

Achieving exceptional clarification performance in beer filtration using traditional precoat filters and trap filtration requires a well-integrated approach that incorporates the right filtration aids and equipment. ATPGroup offers a comprehensive solution that leverages top-of-the-line products from both its own portfolio and its partnerships with Imerys and Eaton, optimizing every step of the filtration process.

1. Precoat Filtration with Diatomaceous Earth (DE) or Perlite:

Diatomaceous Earth (DE) creates a porous precoat that captures fine particulates while maintaining high flow rates. The Imerys Celite® DE is engineered with low Beer Soluble Iron (BSI) content to enhance both flavor and colloidal stability while achieving brilliant clarity.

With high solids-holding capacity, perlite offers an alternative to DE in precoat or body feed applications. The Imerys Harborlite® Perlite provides various permeability options for tailored clarification and throughput needs.

2. Cellulose-based Precoats:

Cellulose-based precoats stabilize cake formation, minimize pressure shocks, and allow for easy cake removal during cleaning, which is especially useful when working with older or damaged filter screens. It enhances the performance of the precoat filter by providing an additional layer of protection and stability. ATPGroup offers two grades of Fiber Floc precoat: Fiber Floc 10 for primary filtration and Fiber Floc 30 for polish filtration.

3. Depth Filtration:

Eaton BECO® Standard Depth Filter Sheets are made of cellulose, DE and resin. They offer excellent clarification over a wide range of nominal retention rates.

Eaton BECOPAD® Depth Filter Sheets are made of alpha cellulose. They are DE-free. Their high purity and high wet strength results in superior performance.

Eaton BECODISC® R & R+ Lenticular Stacked Filters come in forward-flow R and back-flushable R+ models and offer a compact footprint for high-volume filtration.

4. Final Trap Filtration:

BECO MEMBRAN® PS Beer Membrane Filter Cartridges are absolute-rated for high-performance particulate removal. They ensure that the product is free of unwanted particles, offering a superior safeguard in the final filtration step.

BECO PROTECT® FS Cartridges: Nominal-rated depth filtration cartridges that act as pre-filters to the membrane cartridges, maximizing throughput and enhancing the life of the final membrane filters.

By combining these advanced filtration aids and media, you can significantly improve clarity, flavor stability, and the overall quality of your beer. Whether using DE, perlite, or advanced depth and membrane filters, ATPGroup’s integrated solutions ensure that your filtration process is optimized from start to finish, delivering bright, stable, and high-quality beer.
