Filtration

Koch Membrane Systems Inc. (KMS), a developer and manufacturer of membranes and filtration systems, recently announced it is offering its Fluid Systems TFC-SR3 spiral nanofiltration elements for dairy applications. The SR3 elements lower operating costs for a variety of dairy selective rejection applications, company officials say, including de-ashing and separation of carbohydrates and proteins.

Ideally suited for whey pre-concentration, salt whey diafiltration and lactose demineralization, the SR3 elements from KMS utilize a proprietary polyamide thin-film composite membrane. The molecular weight cut-off is such that the membrane will pass monovalent salts like sodium chloride, yet retain divalent salts, proteins and sugars. The company says retention of sugars, such as lactose, typically exceeds 99 percent.

The SR3 dairy elements are specifically designed to conform to USDA 3-A and FDA guidelines. For cleaning-in-place, the allowable pH range is 2.0 to 11.0. For continuous operation, the pH range is 3.0 to 10.0.

Fluid Systems TFC-SR3 spiral elements are available in 4- and 8-inch diameters at the standard 38- and 39-inch lengths.

Koch Membrane Systems Inc. will showcase its Fluid Systems TFC-SR family of nanofiltration spiral elements for dairy applications at the Worldwide Food Expo 2007 Oct. 24-27 in Chicago.

The Fluid Systems TFC-SR family elements lower operating costs for a wide variety of selective rejection dairy applications, company officials say, including de-ashing and separation of carbohydrates and proteins.

Ideally suited for whey pre-concentration, salt whey diafiltration and lactose demineralization, the SR elements utilize a proprietary polyamide thin-film composite membrane. These spiral-wound elements are a cost-effective solution for dairy and other food processing applications where the feed stream is of low solids density and minimal floor space is available, company officials say.
