SolarSpring Membrane Distillation

A membrane material which is both hydrophobic and microporous separates the liquid from the distillate, but allows vapours to pass. The driving force for the distillation is a temperature difference, or partial vapour pressure respectively between an evaporator and a condenser channel. In between the hot and cold channel lies the distillate channel, which is separated from the other channels by a condenser film towards the condenser channel and a membrane on the evaporator side. As only vapours can pass the membrane a highly pure distillate is generated. The process operates at low temperatures of 35-95 °C and at ambient pressure, which reduces operational and maintenance costs.

Depending on the application, one of five different membrane distillation channel variants is implemented:

  • Permeate Gap MD (PGMD)
  • Direct Contact MD (DCMD)
  • Air Gap MD (AGMD)
  • Vacuum MD (VMD)
  • Vacuum Air Gap MD (VAGMD)

Advantages of MD-technology:

  • High chemical resistance towards corrosive or acidic process liquids
  • Maintenance friendly systems with simple component replacement
  • System integration into existing processes
  • Competitive economics compared to state of the art solutions

SolarSpring Filtration Systems

Our drinking water filtration systems are a smart combination of 5 stages; an Ultrafiltration module, a sandfilter, a disk filter, an activated carbon stage and an Ultraviolet-Disinfection unit. Interaction between the stages is synchronized and fully automatic – self-sufficient cleaning cycles enable a constant and smooth operation. A cubic meter of drinking water only takes 0,3 kWh of electric energy to produce at an operating pressure at 2,5 bar.

Night time operation is sustained by an AGM-Batterie which is charged during the day time through the solar panel and charge controller- all included in the package. For remote monitoring, a 3G module can be added to the Siemens Logo PLC so that you always have an eye on all the important parameters.
