Dairy industry brines

Brines from dairy processing are often highly variable and complex, with fluctuating quality, high organic loads, elevated salinity, and widely varying pH. These brines typically originate from Reverse Osmosis (RO), Electrodialysis (ED) and direct from production processes, and are challenging for conventional concentration systems to handle. Dyvar® concentrates and crystallizes these demanding, often mixed brines.

Why dairy plant operators choose Dyvar®

Discover the unique advantages that make Dyvar® the smart choice for sustainable brine concentration:

Reliable performance in complex streams

Stable performance with fluctuating salt matrices, organics, and extreme pH (high/low).

Maximum water recovery, minimum waste

Achieves high water recovery while reducing brine volumes, lowering disposal costs, and ensuring compliance with tightening discharge regulation.

Fractional crystallization for value recovery

Enables selective salt and nutrient recovery by combining concentration and crystallization in one compact technology.

Compact, plug & play, cost-efficient

Combines concentration + crystallization in one containerized, quick-start system reducing CAPEX/OPEX versus multi-unit setups and supporting compliance with tightening discharge regulations.

Case study

Transforming dairy brine into valuable resources

Lactoprot Deutschland GmbH is a specialized milk processor producing sour caseinates from pasteurized milk and whey. The company is committed to high resource efficiency and environmental responsibility, utilizing nearly all components of milk and whey to minimize waste streams. One of the few remaining waste streams is a reverse osmosis (RO) brine, rich in milk salts, chlorine and organic substances.

Due to tightening environmental regulations driven by growing concerns over drought and salinity, Lactoprot was no longer permitted to discharge its saline wastewater into the local municipal treatment plant. As a result, the company was forced to transport the brine by truck to larger municipal facilities in northern Germany, incurring high disposal costs and facing acceptance challenges. To address this issue, Lactoprot partnered with Salttech to implement a sustainable and compliant solution for managing its saline waste stream.
