Feed water

Dairy Product Total Solids Limits The maximum total solids (T.S.) for sweet whey, acid whey, skim milk, and whole milk vary depending on the feed spacer (31, 46, 65, 80 mils).

• Sweet Whey Max. T.S.: 15-30
• Acid Whey Max. T.S.: 15-28
• Skim Milk Max. T.S.: 14-28
• Whole Milk Max. T.S.: 15-35

See the official PDF for exact tabulated values per feed spacer size.

Mechanical / hydraulic

Element Dimensions Elements are available in various model numbers with different diameters (B), lengths (A), and permeate water tube (P.W.T.) IDs. For example:

• 1812F: Diameter 1.8 in, Length 12 in, P.W.T. ID 0.63 in
• 2540F: Diameter 2.5 in, Length 40 in, P.W.T. ID 0.63 in
• 8038: Diameter 8.0 in, Length 38 in, P.W.T. ID 1.14 in See the official PDF for exact tabulated values for all models.

Element Weights Element weights vary by model and range from 0.5 kg (1.0 lb) for smaller elements (e.g., 1812F) to 22.7 kg (50 lb) for larger elements (e.g., 10338). See the official PDF for exact tabulated values for all models.

Recommended Element Cross Flow Rate Recommended cross flow rates vary significantly based on element diameter and feed spacer size (24, 31, 46, 65, 80 mils). For example, for a 1.8" element, flow rates range from 1 m³/hr (4 gpm) to 2 m³/hr (7 gpm). For a 10" element, flow rates range from 42 m³/hr (184 gpm) to 68 m³/hr (299 gpm). See the official PDF for exact tabulated values for all models and feed spacer sizes.

Membrane Area (sq. ft.) Membrane area varies by model number and feed spacer size (24, 31, 46, 65, 80 mils). Values are not available (N/A) for all combinations. For example:

• 1812F: 3.6 sq. ft. (31 mils feed spacer)
• 2540F: 22-34 sq. ft.
• 8038: 189-414 sq. ft.
• 10338: 326-620 sq. ft. See the official PDF for exact tabulated values for all models and feed spacer sizes.
