Separation and Concentration Purification Request with Lenntech

Please contact us:

for your industrial separation, filtration, concentration, and purification case studies.

In the past Lenntech has been asked to investigate, test, resolve and propose solutions to these types of challenges:

  • Remove divalent salts (Ca, Mg) from industrial process water.
  • Concentrate Sodium Chloride (NaCl) brine from 215 to 245 g/liter
  • Purify and concentrate hydrogen peroxide (Hâ‚‚Oâ‚‚)
  • Auto-regenerate an activated carbon bed
  • Concentrate C5/C6 sugars in a saline and acidic solution
  • Reduce salts to prevent too frequent Ion Exchange bed regeneration
  • Ethanol dehydration
  • Adsorption of Stevia Glycoside, Steviol, Stevidin and Flavonoids substance removal
  • Separate chlorates from feed water in the food industry.
  • Remove humic substances from surface water
  • Ammonium removal from fertilizer wastewater
  • Ethylene Glycol rejection
  • Heavy metals filtration (Molybdenum MO, Copper CU, Lead Pb, Zinc Zn) - Extraction of metal oxides
  • Color removal from textile run-off water
  • Purification and Recycling of Membrane Bio Reactor (MBR) effluent.
  • Treatment of persistent organic pollutants (Pops)
  • Desalination of organic liquids
  • Convert Sodium Sulphate (Naâ‚‚SOâ‚„) into Caustic (NaOH) and Sulphuric Acid (Hâ‚‚SOâ‚„)
  • Zero Liquid discharge (ZLD) of factory outlet
  • Dehydration of mixture of organic acids
  • Non-biodegradable COD oxidation in leachate water after biotreatment of biomass
  • Lithium extraction from mining water
  • Protein recovery - downstream Bioprocessing bacteria, enzymes, chloroplasts
  • Dissolved Solids removal (TDS & TSS) in ultrapure water
  • Colloids removal measurement (SDI)
  • Controlled ion exchange column trials evaluating; loading, rinse and regeneration in a controlled environment.
  • Cooling tower blowdown water purification preventing chemical precipitates
  • Neutralisation of acidic streams
  • Oxidation of halogenated hydrocarbons
  • Sugar cane & juize decolorization, Citrus debittering, juice deacidification, sugar demineralization
  • Biofouling and scaling prevention on membranes
  • Desalinate water with high Silica content
  • Treatment of spent caustic
  • Solid–liquid separation and mineral processing
  • NOM >90% and atrazine reject elimination
  • PFAS removal systems for well water
  • Heap Leaching - Cyanide/Ammonia/Alkali/Acid chemical leaching ore (gold, silver, nickel and uranium)
  • Phosphorus removal system for liquid manure
  • Manganese Removal from Drinking Water Sources
  • Selective Sodium removal from horticulture/agriculture recycle water
  • Lowering the concentration of salts or solvents from solutions containing proteins, peptides, nucleic acids, and other biomolecules

We provide a first theoretical analysis of concept for free if we see possibilities for treatment.
As second step we can do a lab scale/bench sale test with a sample for a proof of concept (POC) feasibility study providing budget costs and parameters after which we could scale-up the process/technology to pilot and or full-scale.
