Reducing Dependence on Imported Dairy Membranes: A Practical Route for Russian Dairy Processors

For many years, European and U.S. equipment and membrane suppliers have maintained strong market influence in dairy membrane processing.

Ultrafiltration, microfiltration, nanofiltration and reverse osmosis technologies are widely used in milk concentration, whey processing, protein fractionation, lactose reduction and other dairy applications.

However, replacing an imported membrane system is not simply a matter of finding another membrane element with similar specifications.

The real question is:

Can the alternative solution achieve the required separation objective while maintaining acceptable cleaning performance, product recovery, operational stability, service life and overall operating cost?

This consideration is particularly important for Russian and CIS dairy processors seeking more flexible equipment solutions and diversified membrane supply chains.

Start with the Product, Not the Membrane

An ice cream production application provides a good example of this principle.

The customer does not necessarily need to completely separate every component in milk.

The actual objective may be:

to effectively separate casein and whey fractions, and then reuse these separated components in product formulation to improve the quality and characteristics of the final ice cream product.

This reflects an important engineering principle in dairy membrane processing:

Dairy companies do not need “more membrane technology.”

They need the right separation process designed around the target product.

Depending on the product objective, membrane processes may involve:

Bacteria and spore removal

Casein/whey fractionation

Whey protein concentration

Lactose and salt reduction

Milk or yogurt concentration

Process water recovery and reuse

Combination of ceramic MF/UF with polymeric UF/NF/RO technologies

Jiuwu Hi-Tech’s dairy membrane technology portfolio provides solutions for different separation requirements, including ceramic microfiltration for bacteria removal and casein/whey fractionation, as well as ultrafiltration, nanofiltration and reverse osmosis technologies for downstream concentration and purification.

Why Dairy Processors Are Looking Beyond Conventional Imported Spiral-Wound Membranes

Spiral-wound polymeric membranes remain widely used in the dairy industry for good reasons.

They offer high membrane packing density, relatively low initial investment and good energy efficiency in suitable applications.

However, in some dairy applications involving high protein and fat content, long-term membrane fouling control and operational stability can become important challenges.

Proteins and fats may accumulate on the membrane surface, within membrane pores and in feed channels, making flux recovery increasingly difficult.

Over long-term operation, repeated chemical cleaning, temperature limitations and material ageing may affect membrane replacement frequency and overall system availability.

For dairy processors, these factors create hidden lifecycle costs.

The membrane with the lowest initial purchase price does not necessarily provide the lowest total cost of ownership.

What Value Can Ceramic Membranes Bring?

Ceramic membranes take a different approach.

In demanding dairy applications, their key advantage comes from the durability of ceramic materials.

Compared with conventional polymeric membranes, ceramic membranes generally offer better chemical stability and temperature resistance. Under appropriate membrane material selection, module configuration and system design, they can tolerate more intensive cleaning conditions and stricter hygiene requirements.

This advantage becomes particularly valuable when long-term operational stability, cleaning recovery and equipment availability are more important than minimizing initial membrane cost.

Jiuwu Hi-Tech’s dairy membrane experience demonstrates that, under suitable membrane materials, module configurations and system designs, ceramic membranes can withstand acid/alkali cleaning, elevated-temperature operation and corresponding sterilization conditions.

The value of ceramic membranes is not simply that they are “stronger membranes.”

More importantly, they can provide:

Better cleaning recovery → More stable operation → Fewer membrane replacements → Less production interruption

Membrane Replacement Cost Is More Than the Membrane Price

When comparing imported polymeric membrane systems with ceramic membrane alternatives, purchase price is only one factor in lifecycle evaluation.

A comprehensive comparison should include:

Membrane replacement cost

How many membrane elements need to be replaced each year? What is the replacement cycle?

CIP cleaning cost

How much acid, alkali, cleaning agent and rinse water are consumed?

Production downtime

How much production time is lost due to cleaning, maintenance or membrane replacement?

Product loss

Are valuable proteins lost through waste streams, or are there losses caused by insufficient separation performance?

Labour and maintenance requirements

How much operational intervention and spare-part support does the system require?

Service and supply-chain risk

How quickly can replacement membranes, seals and technical support be obtained?

For Russian and CIS dairy processors, supply-chain reliability has become an increasingly important consideration.

Even if a membrane is technically suitable, uncertain spare-part availability or unpredictable delivery times may reduce its actual production value.

Do Not Simply Replace Imported Membranes One-for-One

This is where many import-substitution projects encounter challenges.

Some plants simply remove existing imported membrane elements and look for products with identical specifications.

However, membrane separation is a complete process system, not just a replacement component.

The final separation performance depends on multiple factors, including:

Feed composition

Protein concentration

Fat content

Temperature

Viscosity

Target product

Concentration factor

CIP cleaning procedures

Downstream process requirements

For example, a plant producing whey protein ingredients may require a completely different membrane process compared with an ice cream producer performing casein/whey fractionation.

Even dairy plants producing similar products may require different system designs due to differences in raw materials and production objectives.

Therefore, a successful membrane replacement project should follow this approach:

Existing Process → Product Objective → Feed Analysis → Pilot Testing → Membrane Selection → CIP Verification → Industrial Design

This approach reduces the risk of simply replacing imported membranes while reproducing the limitations of the original process.

From Import Substitution to Better Dairy Processing Solutions

For Russian dairy processors, import substitution does not mean accepting lower technical performance.

Instead, it can provide an opportunity to optimize production processes and reduce lifecycle costs.

If an existing production line suffers from frequent membrane replacement, difficult cleaning, unstable flux or limited technical support, the key question should not be:

“Can the new membrane element fit into the existing membrane housing?”

The more valuable question is:

“Can this separation step be redesigned to reduce lifecycle costs while maintaining the required product quality?”

This shift changes the discussion from simple component replacement to overall process-value optimization.

For applications including casein/whey fractionation, bacteria removal, whey protein concentration and dairy ingredient purification, Jiuwu Hi-Tech can combine ceramic and polymeric membrane technologies according to the customer’s actual product objectives and provide customized membrane separation solutions.

For dairy projects in Russia and the CIS region, Jiuwu Hi-Tech can evaluate existing membrane systems based on feed composition, current equipment configuration, membrane operating performance, CIP procedures, production capacity and target products, and determine whether direct replacement or process optimization can provide better lifecycle economics.
