Where membrane concentration changes the economics
Discharge compliance, brine mining, lithium, and produced water. Four different industries arrive with the same expensive step, and the same concentration platform sits underneath all four.
Minimum & zero liquid discharge
- Membranes to 280,000 mg/L, so the crystallizer sizes against what is left
- 60–75% lower energy and capital than a thermal train
Brine mining & resource recovery
- Magnesium, potassium, bromine, lithium and salts concentrated to economic strength
- 99%+ overall water recovery alongside the product stream
Lithium & critical minerals
- 3–6 months versus 18–24 months solar evaporation
- 200 g/L lithium salt to crystallization, compatible with any DLE process
Produced water
- 3–7 barrels of water arrive with every barrel of oil
- Disposal is priced by volume, so every barrel removed is a barrel unpaid
Concentrating past 90,000 mg/L has always meant boiling water, and the capital cost of an evaporator is what makes most of these projects marginal.
Doing the same work on membranes moves the capital cost, the energy bill and the compliance position at once—which is why four unrelated-looking problems have the same answer.
The advantage of one platform
The practical consequences of technologies designed against each other from the start.
- One concentration curve
- SAMRO™ hands MBC™ a feed it was designed to receive, so there is no interface stage built only to reconcile two vendors' assumptions.
- Shared utilities
- One pretreatment train, one chemical inventory, one power and instrument-air supply across the stages.
- One accountable designer
- Osmosys designs the integrated train and stays responsible for its performance basis—there is one operating picture and one party answerable for it.
- Phased capital
- The stages are modular. Primary concentration can be built first and the brine stage added when the discharge limit or the product case requires it.
- Headroom on the feed
- The same equipment tolerates a wider feed envelope than it is specified against, which is what absorbs a change in the upstream process later.
By industry
A semiconductor fab, a copper mine and a gas field produce very different water. What they share is a stream too concentrated for conventional membranes and too dilute for a crystallizer.
Semiconductors
Ultrapure water production leaves a high-TDS reject under ZLD mandates, in facilities where footprint is fixed.
SAMRO™ · MBC™
Oil & Gas
Produced water at disposal-well volumes, often carrying lithium and minerals worth more than the disposal costs.
SAMRO™ · MBC™ · selective extraction
Mining
Tailings water and acid drainage holding recoverable copper, zinc, and nickel alongside the remediation duty.
SAMRO™ · MBC™
Pharmaceuticals
High-value solvents leaving API manufacturing as regulated hazardous waste, recoverable at reuse specification.
MBC™
Salt & Caustic Soda
Electrolysis needs high-purity brine at crystallization strength, a duty usually bought with thermal energy.
SAMRO™ · MBC™
Desalination
Specific energy sets the power bill for the life of the plant, and the brine still has to go somewhere.
