INDUSTRIAL PROCESSES
Membrane systems can be implemented at various unit processes in the metals extraction circuit such as leaching, solvent extraction, elution, electrowinning, waste ponds and water balancing.
There are also applications in the chemicals, dairy and food processing industries for all corrosive,
highly concentrated and high temperature solutions.

Acid recoveryRecovery, purification and
concentration of acid such as - H2SO4; HCl; HNO3; H3PO4, etc |
Alkaline recoveryRecovery, purification and concentration of bases such as -
NaHCO3; NaOH; KOH; LiOH, etc |
Metals recovery &
Volumetric reduction and concentration of metals improve process throughput simultaneously reducing operating expenses.
|
Acidic ProcessesAcid-stable membranes are used to selectively separate and purify acidic stream whilst simultaneously concentrating the divalent ions in the solution typically metals or impurities.
Neutralization of acidic streams are a substantial cost driver for any process producing difficult slags that need to be disposed. Purifying and recycling acid reduces fresh acid consumption, neutralization chemical consumption and environmental impact showing measurable process savings. |

Alkaline ProcessesMembrane applications in alkaline processes are effective in separating organic contaminants from caustic liquors such as cleaning solutions from food, beverage and diary systems.
Selective separation of monovalent metals in alkaline streams and leach reagent recovery are key applications in Mining and Minerals extraction processes. |

Product ConcentrationConcentration of products are an added benefit of acid and alkaline recovery processes. The divalent ions in solution are rejected by the membranes into the Concentrate stream and water together with other monovalent ions into the Permeate stream.
Volumetric reduction, concentration and separation of metals improve process throughout simultaneously reducing operating expenses. Membrane systems have proven to be extremely efficient in treating low concentration metals from waste ponds. |
