Liquisol technologies

Powerful solutions for water treatment & heat management

Our technology portfolio covers Multi-Effect-Distillation (MED), Multi-Stage-Flash (MSF), H-Xtreme™ heat exchangers and membrane contactors. Each unit is built on our modular polymer-based Liquisol modules: highly configurable, easily scalable and designed for demanding industrial applications.

Heat management

H-Xtreme™ Heat Exchangers

Compact, lightweight, and highly durable heat exchangers built on an advanced HPC (high-performance polymer with graphite) material platform.

H-Xtreme™ HPC heat exchanger
  • Graphite corrosion resistance + polymer shock resistance
  • Metal-grade thermal efficiency with low-fouling surface
  • Resistant to thermal and mechanical shock
  • Easy cleaning and on-site repairability
  • Fast delivery: 6–8 weeks
Engineered for uptime, maintainability, and low total cost of ownership.
Membrane contactors

Polymer-based membrane contactor modules

Liquisol modules can be configured as membrane contactors for liquid and gas streams, driven by chemical potential differences instead of pressure or temperature alone.

  • Enables a wide range of separation and transfer operations beyond classical thermal processes.
  • Compatible with combinations of thermal and membrane-based stages in one system architecture.
  • Beneficial when processing heat-sensitive media or when energy sources are constrained.
Driving forces can be tuned via composition, partial pressures and operating conditions for each specific application.
Thermal separation

Film-vacuum Multi-Stage-Flash (FVMSF)

A polymer-based implementation of the Multi-Stage-Flash process, operated in partial vacuum at temperatures well below 100°C.

Film-vacuum Multi-Stage-Flash process diagram
  • Thin polymer films as condensation and heat transfer surfaces for high thermal performance and excellent corrosion resistance.
  • Concentrate stream passes a series of stages with decreasing temperature and pressure — each stage generating vapor through flash evaporation.
  • Counter-current feed stream serves as coolant, condensing vapor and forming the distillate stream.
High thermal efficiency is achieved by reusing the transferred evaporation energy across a series of stages.
Thermal separation

Film-vacuum Multi-Effect-Distillation (FVMED)

A completely polymer-based implementation of the Multi-Effect-Distillation process, for example used in multi-column distillation systems.

Film-vacuum Multi-Effect-Distillation process diagram
  • Each effect is heated by a vapor stream that is condensed to form distillate while providing energy for new evaporation.
  • Thin polymer films as heat transfer surfaces enable high thermal performance and corrosion resistance.
  • Operation in partial vacuum at temperatures well below 100°C for energy-efficient and gentle processing.
Condensate streams add up to the overall distillate, while the remaining feed forms the concentrate stream.
Liquisol applications

Smart and modular technology across industries

Liquisol offers water separation processes and integrated heat management solutions with a multitude of applications. Systems can produce purified water, concentrate complex solutions, or provide efficient heat exchange — often far beyond the constraints of conventional membrane or metal-based systems.

Modular Platform

Implementation of several separation processes within the same modular technology platform.

High Concentrations

Concentrations close to saturation limits thanks to corrosion-resistant polymer-based apparatuses.

Thermal Efficiency

High thermal efficiencies through multiple reuse of evaporation energy in series of stages or effects.

Scalable Design

Modular design with excellent scalability, from pilot scale to industrial capacities.

Corrosion Resistant

Fully polymer-based systems resistant to aggressive cleaning agents and challenging media.

Low-Temperature Operation

Low-temperature processes, enabling the use of low-grade heat sources (e.g. solar heat) and gentle handling of heat-sensitive agents.
