Filtration Solutions for Dairy Production

Alfa Chemistry provides filtration equipment, services, and process safety to cheese, market milk, and dairy ingredient manufacturers all over the world. From general clarity to high-end protein separation, our filtration systems can handle a wide range of filtration needs. With our comprehensive choice of filtration technologies, you can keep the flavor and nutritional content of dairy products.

Reliable Cheese Brine Purification

Brine is used to marinading a variety of cheeses. The fat, curd particles, and microbes in the cheese, as well as the accumulation of protein and other components, create a nutrient-rich habitat for the anti-salt microorganisms during the repeated soaking process. Reused brine can harbor dangerous microorganisms including gas- or pigment-producing bacteria, yeasts, and molds, or salt-tolerant diseases that can taint cheese and degrade its quality. To maintain constant daily production, good control of the brine and brine activities is required.


Please contact us to learn more about the fat, curd particles, and bacteria that are soaked in cheese on a regular basis and how our solution might help.

Milk Fractionation

Dairy product innovation is being driven by the need for specialty products with unique sensory attributes, nutritional characteristics, or added functions. From microfiltration to the manufacture of bespoke fractions, Alfa Chemistry cross-flow membrane technology delivers exact separation.

A ceramic membrane consists of a porous support layer and a filter layer and is used for ultrafiltration and microfiltration. Membrane materials (alumina, zirconia, and titania) are resistant to a wide range of pH, chemicals, temperature, and pressure. The multi-channel membrane's remarkable compactness, paired with its high permeability, allows for fast throughput processing of enormous volumes. A longitudinal permeation gradient exists in the membrane, allowing uniform and calibrated penetration along the flow channel. In a steady microfiltration scheme, this results in a large increase in the overall utilization of the membrane surface.


QC Microbial Detection

The enhanced microbial retention II filter element is a hydrophilic membrane filter that reliably retains bacteria in the final filtration of bottled water. The II JSD filter was created and tested to improve, safely, and consistently eliminate germs from bottled water. Serial layers of 0.2 and 0.1 micron polyvinylidene fluoride (PVDF) membrane make up the cartridge. This filter's integrity can be checked. Filter performance may be guaranteed in minutes using in-situ and non-destructive integrity testing.

Whey Defatting

The Alfa Chemistry GP membrane is designed to transport soluble macromolecules through the microfiltration membrane as efficiently as possible. The natural pressure drop causes an asymmetric transmembrane pressure (TMP) from the inlet to the outlet of the flow channel under typical microfiltration settings. The Alfa Chemistry GP membrane includes a longitudinal permeability gradient incorporated into the support structure to compensate for this TMP drop without the need to change the filter layer. This design ensures that the entire membrane has a robust microfiltration system.
