Membrane Solutions for Dairy Processing
Polymeric membranes and application expertise for whey, milk protein, lactose, brine, and water recovery operations.
Where membrane performance creates value
Every dairy processor works to maximize yield recovery while keeping production running safely, efficiently, and consistently. Over time, however, membrane performance naturally changes. Small shifts in retention, fouling, and cleaning efficiency develop gradually, making them difficult to distinguish from normal process variation.
Those changes rarely create an immediate operational issue. Instead, they quietly reduce yield, increase cleaning frequency, consume more energy and chemistry, and add variability to production. By the time the impact appears in operating costs or financial results, valuable recovery opportunities may have already been missed.
Six value gaps

Yield
Product recovered per pound of milk solids processed

Uptime
Hours of production protected from unplanned interruption

Operating cost
Chemistry, energy, and labor reduced per production day

Sustainability
Water, energy, and waste reduced across the membrane life

Capacity
Throughput recovered without capital expansion

Product
Specification consistency that protects premium grades
Solecta’s Dairy Map Process
Solecta manufactures the full polymeric membrane portfolio used in dairy separation, spanning microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Every element is engineered for the product chemistry, fouling profiles, and yield demands of dairy processing.

Dairy applications
Each application in the map corresponds to a specific Solecta element, engineered for that stage of the process.
| Application | Tech | What it does | Value created | Element |
|---|---|---|---|---|
| Whey protein concentration | UF | Concentrates whey protein into WPC and WPI streams | Protein captured per pound of whey processed | PE10K, PE5K, PE5K HC |
| Whey defatting | MF | Removes residual fat upstream of UF | Cleaner protein stream · Higher WPI grades · Lower UF fouling | PV0.3M |
| Milk protein separation | MF | Separates fat from skim for protein standardization | Consistent protein-to-fat ratios · Extended shelf life | PV0.3M |
| Lactose concentration | NF | Concentrates lactose from UF permeate for powder and demineralized streams | Recovered lactose value · Lower evaporator load | NF300 |
| Cheese brine clarification | MF | Removes bacteria, yeast and mold from cheese brine | Brine reuse · Extended brine life · Lower disposal cost | PV0.1M |
| RO water recovery | RO | Reclaims water from process streams for plant reuse | Water cost reduction · Lower effluent discharge volume | ROPlus |

Plant-wide adoption within one quarter
A Wisconsin cheese processor installed Solecta PV0.3M elements on one of three parallel whey MF trains and compared performance against two incumbents. The Solecta train delivered a 5.76% protein yield increase, recovering an additional 16.2 pounds of protein per hour. Based on current protein prices of $14 per pound, the membrane investment paid for itself in approximately 10 days. The processor expanded PV0.3M across all three trains, recovering approximately 292,000 additional pounds of protein annually.
- +5.76% | Protein Yield
- ~292,000 lb/yr | Additional Protein
- ~10 days | Element Payback

Frequently Asked Questions
Every element reaches a point where it costs more to operate than to replace. For most UF dairy loops, this falls between month 9 and month 12. Monitoring flux trends, protein transmission, and cleaning recovery helps identify that point based on actual performance rather than a fixed schedule.
Across documented engagements, Solecta has helped dairy processors achieve 5 to 15% increases in protein yield. One Wisconsin cheese processor saw a 5.76% increase within a single quarter after installing Solecta PV0.3M elements, recovering approximately 292,000 additional pounds of protein annually.
The purchase price of a membrane element typically represents about 10% of its total economic impact. The remaining 90% comes from yield loss, quality downgrades, energy, cleaning chemistry, reactive labor, and unplanned downtime over the element’s operating life.
Solecta manufactures polymeric membranes across the full dairy separation spectrum: whey protein concentration (UF), whey defatting (MF), milk protein separation (MF), lactose concentration (NF), cheese brine clarification (MF), and RO water recovery. All elements meet FDA CFR Title 21 and EU EC 1935/2004 compliance standards.
