Ten industry verticals where EvapCryst delivers engineered evaporation, concentration and crystallization systems — from high-salinity wastewater compliance to battery-grade crystal production.
Each vertical has its own feed chemistry, regulatory drivers, product targets and operating constraints. We engineer systems around the feed — not the other way around.
High-COD and mixed-salt systems engineered for compliance and recovery.
Typical streamsEngineered for purity and traceability.
Typical streamsZLD and selective mixed-salt separation.
Typical streamsStreams that defeat conventional biological or membrane treatment — engineered ZLD with honest boundary statements.
Typical streamsThermal sensitivity and sanitary-grade design driving vacuum cooling crystallization and hygienic falling-film concentration.
Route cards show primary solution lines per vertical — secondary intersections (e.g. ZLD on battery streams, retrofit on wastewater sites) are handled case-by-case. Typical mapping only: final routing depends on feed characterization.
Every vertical below has a dedicated industry hub with process chemistry, reference routing and solution mapping. If your stream is not listed, send it anyway — final routing follows feed characterization, not page inventory.
Extraction · Salt conversion
Rare earth extraction liquors, copper/zinc/nickel smelting wastewater ZLD, cobalt hydroxide and battery-precursor grade CoSO₄ crystallization for high-value metal recovery.
FGD wastewater · Zero discharge
Flue-gas desulfurization wastewater, power plant circulating blowdown and steel mill effluent — high-chloride, high-TSS and mercury/selenium-bearing streams under tightening rules.
Dye wastewater · Salt recovery
Dyeing wastewater ZLD, caustic soda recovery from mercerizing, mixed-salt separation and dye recovery — high-COD, high-color and high-salinity effluent with heat integration.
Alkali recovery · Concentration
Kraft black liquor concentration, sulfite red liquor, alkali recovery and biomass process streams — high viscosity and severe scaling driving cascade falling-film to forced-circulation.
GMP · Polymorph control
API crystallization, polymorph control, solvent recovery and pharmaceutical wastewater ZLD — GMP-grade equipment, CIP/SIP integration and validation-ready documentation.
Fumaric acid evaporation and crystallization solutions: recovering saleable acid from mother liquors and saline wastewater by three-effect or MVR concentration into external-circulation crystallizers, with substantial condensate COD reduction.
Membrane bioreactors have become the standard biological front end for large textile effluent plants precisely because they produce an effluent the downstream stages – reuse RO, or a ZLD evaporation
How crystalline MAP is produced: neutralize wet-process phosphoric acid with ammonia, concentrate in falling-film and forced-circulation evaporators, crystallize in FC or DTB/Oslo crystallizers, and cut steam cost with MVR. Covers
Evaporation systems for starch sweetener plants: five-effect and MVR falling film trains from 10% to 77% solids, the chromatographic 60% DS interface, ion exchange integration, and CIP engineering.
Zinc sulfate crystallization plants built around DTB crystallizers that switch between monohydrate evaporation mode and heptahydrate cooling mode, with triple-effect or MVR energy supply and integrated centrifuge, drying and packing.
Plant protein and biological feed processing solutions: MVR falling film concentration of fermentation broths and protein liquors at 60-80C, viscosity and foaming control, and integration with spray and fluid-bed drying.
