Recover valuable products, chemicals and reusable process streams from dilute or complex feeds while reducing the final liquid and solids load.
Recover value before treating the remainder as waste.
Industrial evaporation and concentration system engineered for volume reduction and recovery
Higher Product YieldReduce valuable material loss
Lower Stream VolumeReduce downstream thermal load
Reusable ChemicalsReturn suitable streams to process
Reduced ResidueMinimise final disposal requirement
The recovery question
What is present in the stream, what has value, and what form must it reach for reuse or sale?
Value identificationDetermine the valuable product, chemical, solvent, acid, salt or reusable component present in the stream.
Recovery specificationDefine purity, concentration, physical form, recovery percentage and reuse or finishing requirement.
Energy strategyUse membrane or physical pre-concentration where feasible before applying thermal concentration.
Residue strategyPlan the remaining liquid, impurity or solid fraction as part of the overall process rather than as an afterthought.
Value-recovery pathway
Identify, concentrate, recover and finish
The process route depends on product chemistry, volatility, solubility, temperature sensitivity, fouling tendency and required final form.
01Identify ValueDefine recoverable component and economics
02Pre-treatRemove limiting impurities and suspended matter
03Pre-concentrateReduce volume using selective physical processes
04ConcentrateApply thermal or hybrid concentration
05RecoverSeparate product, chemical, solvent or salt
06FinishCrystallise, dry, package or return to process
Technology platforms
Combine membrane, thermal and solids-finishing systems
Membrane Pre-concentration
RO, NF and selective membrane systems reduce stream volume before thermal processing.
Thermal Concentration
Vacuum evaporation, MEE and mechanical-vapour-recompression configurations.
Crystallisation & Solids
Controlled crystallisation, ATFD and salt or product-solids recovery.
Drying & Final Form
Spray, belt and other drying routes selected around product properties and quality.
Process selection
The lowest-load practical recovery route
Use membranes where separation permitsMembrane pre-concentration can reduce the hydraulic and thermal load without phase change.
Use heat where concentration requires itThermal systems are selected around boiling-point elevation, viscosity, scaling and product stability.
Protect the valuable productOperating temperature, residence time, oxidation exposure and contamination risk are controlled.
Design for the residue as wellImpurities, mother liquor, purge and solids handling remain part of the complete mass balance.

Pilot before commercial scale
Validate recovery, quality and operability
Pilot trials establish whether the recovered stream meets the required purity, concentration and reuse criteria—and whether the process remains stable over time.

Is valuable product leaving with a dilute or waste stream?
Share the stream composition, flow, target recovery, required concentration and product-quality limits. YWT can define the test and scale-up programme.
