MEMBRANE TECHNOLOGIES AND ENGINEERING FOR SUSTAINABLE SEPARATION PROCESSES

 

PERVAPORATION

What is Pervaporation?

Pervaporation is a membrane separation technology based on the physico-chemical interaction between the membrane and the permeating molecules. Highly hydrophilic materials, like polyvinyl alcohol, enhance selective sorption and diffusion of water through a thin dense membrane layer. Therefore, pervaporation is ideally suited for the dehydration of solvent mixtures, especially azeotropes where conventional technologies, like distillation, require complex and energy-intensive processes. 

 

CROSS-FLOW FILTRATION

DeltaMem has specific experience in processes like:

  • Polyphenol concentrations and purification

  • Clarification of fermentation broth

  • Protein concentration

  • Edible oil purification

  • Glycoside purification and concentration

  • Fruit juice clarification

For challenging processes involving organic solvents purification processes at temperature higher than 80°C, robust membrane modules are required. DeltaMem cross-flow membrane module are in stainless steel components, the module tightness is ensured without using resins which make it suitable for tough cross-flow operations.

We supply turn key membrane cross-flow filtration plants, starting with pilot tests followed by process engineering.​

 
 

ENGINEERING

DeltaMem develops technical solutions for challenging separations in partnership with industrial users. We perform process scale-up from few millilitres to some cubic meters of organic solvents, going through initial concept design, to process engineering till commissioning of turn-key plants. 

Process modelling interfaced with proprietary software assists the design of unit operations and process set-up, thereby optimizing CAPEX and OPEX.

 

INDUSTRIAL PLANTS

DeltaMem proudly can refer to its long list of realized membrane plants, with excellent services delivered to worldwide customers.

Complete plants supplied by DeltaMem provide the following advantages:

  • Proven and reliable operation with full automatization

  • Robust membranes with long service life

  • Flexibility to adjust flow and dehydration specification to meet changes in production requirements

  • Skid mounted design allowing the plant to be FAT tested before installation for speedy start-up

  • Increased capacity production, which can be built in for slightly higher capital costs

  • Low operating costs
