MemBrine Concentrator™ ceiling: 280,000 mg/L TDS

Membrane infrastructure to replace evaporation. Concentrate brine, recover water and minerals, and reach zero liquid discharge—on standard reverse-osmosis equipment.

Evaporation is the most expensive way to take water out of a stream.

Anyone specifying an evaporator should price the membrane train first.

Wherever brine has to shrink—a discharge permit, a disposal bill, a mineral worth recovering—the incumbent answer is thermal: alloy vessels boiling water at 25 to 60 kWh/m³ of water removed.

Osmosys moves that duty onto membranes. The MemBrine Concentrator™ carries brine to 280,000 mg/L on standard reverse-osmosis equipment, so the thermal step at the end—where a project still needs one—is sized for a fraction of the flow.

The operating envelope

Every stage is a standard reverse-osmosis skid running in its own concentration lane. Together they carry a stream from dilute feed to crystallizer-ready brine - the range that used to belong to evaporation.

Applications

A discharge permit, a disposal bill, a mineral worth recovering—each one turns on the cost of removing water.

A different stream?

Most projects arrive as a flow rate, a lab report, and a constraint. That is enough for a first read.

Standard equipment.

The platform runs on standard spiral-wound membranes and standard pressure vessels. No exotic alloys, no bespoke elements, no single-supplier spares list—the equipment a plant already knows how to buy and maintain.

One train, feed to crystallizer.

SEBRO™ and SAMRO™ carry the dilute and mid ranges at high recovery and hand MBC™ a concentrated stream. Where a project still needs a thermal finish, it is sized for a fraction of the original flow.
Explore the platform

From water analysis to operating plant.

Customers bring a stream and an objective, and one team stays accountable from the first sample to steady-state operation.

  1. 01

    Analyze the stream

    Flow, full ionic composition, variability, and the required outlet define the problem before any equipment does.

  2. 02

    Prove the window

    Bench and pilot work on the actual water establishes recovery, energy, pretreatment, and achievable concentration.

  3. 03

    Design the train

    Osmosys integrates its membrane stages with pretreatment, controls, and downstream equipment into one accountable design.

  4. 04

    Deliver and operate

    Equipment supply, commissioning, performance testing, and operation—as far into the plant's life as the project needs.
