Fact Sheet
Dairy HWS
Dairy Industry
Hot Water Sanitization
Meeting Stringent Requirements
Without question, the dairy industry is faced with
increasingly stringent sanitary regulations. To help
meet these requirements, GE Water & Process
Technologies introduces the Dairy HWS family. Ideal
for applications with biologically active feeds, Dairy
HWS elements are designed for hot water sanitiza-
tion (pasteurization) by periodic exposure to tem-
peratures up to 90°C (194°F). An innovative break-
through, you can now sanitize the permeate side of
a membrane element without risking membrane
damage. Additional benefits of Dairy HWS elements
include sanitization without the use of ineffective or
harmful chemicals, as well as protection against
detrimental bacterial growth on the membrane sur-
face – thus limiting replacement costs.
Dairy HWS elements utilize polysulfone parts and
unique element construction to meet the require-
ments for hot water sanitization. Comprised of high
quality materials that meet 3A standards and con-
form to guidelines set by the Code of Federal Regu-
lations, Dairy HWS elements feature a patented
Durasan* Cage protective sleeve that enhances
element integrity by securing the spiral. In addition,
the sleeve improves sanitizing effectiveness by
maintaining a controlled by-pass between the ele-
ment and pressure vessel wall without the use of
traditional brine seals.
Membrane Technology
A Valuable Solution
The use of spiral membrane technology in dairy ap-
plications allows plants to recover valuables, create
saleable products, recycle water and reduce plant
effluent. By utilizing Dairy HWS elements, spiral
membrane systems can strategically concentrate:
 Sweet Whey
 Lactose
 Whole Milk
 Skim Milk
