Rare Earth TENORM Wastewater Treatment Before Thermal ZLD
For rare earth operations working ores that carry uranium and thorium, water closure is a radiological design problem before it is a salinity problem:

Authorized and anonymized project references where each entry documents the feed characterization (TDS, COD, dominant salts), nameplate evaporation duty, configured process route (energy reuse × evaporator type × crystallizer type), and the specific process challenge that drove selection — not a gallery of nameplates. Where client confidentiality prevents full disclosure, only the process envelope and configuration family are published.

For rare earth operations working ores that carry uranium and thorium, water closure is a radiological design problem before it is a salinity problem:
For rare earth smelting and separation wastewater – the streams that carry salt above 10%, pH below 1, COD in the tens of thousands
For rare earth mines whose water problem is hardness, silica and moderate dissolved salts at large flow, the workable route before any thermal ZLD
For rare earth separation plants, ammonia nitrogen treatment is not one process but three, selected by concentration: high-strength streams (tens of grams per liter
MVR evaporation and crystallization system for rare earth metallurgy RO reject: ammonium sulfate and chloride salt recovery, condensate ammonia polishing and ZLD compliance.
Evidence constraint. Only authorized or anonymized project information is displayed on this page. Process parameters cited (TDS, COD, throughput, particle size distribution, steam economy) are bounded by documented operating conditions and should not be extrapolated to other feed compositions, capacities or utility profiles without project-specific re-validation.
