SUCCESS STORY - APPLICATION OF THE RIGHT SENSORS IN AN INNOVATIVE DE-SATURATION SYSTEM

Safe drinking water with innovative technology

Rainmaker Holland B.V. recently asked JUMO to help in developing the right sensors for an innovative desalination system. A major concern was the required corrosion resistance.

Task

Rainmaker specialises in the decentralised development and production of water technology to provide safe drinking water to remote locations worldwide. To achieve this goal Rainmaker has developed two product lines: Air-to-Water and Water-to-Water.

The Challenge

Unfortunately, fresh water is unevenly distributed. Today, an estimated 800 million people worldwide live without access to a source of safe drinking water. In North Africa, the Middle East, India, Mexico and large parts of South America, but also on many islands and in many regions, there is a structural shortage. Precisely in those places where it is difficult to make drinking water accessible, Rainmaker uses innovative techniques.


Solution approach

Air-to-Water solution

A decentralised and renewable energy driven technology from Rainmaker called Airto-Water and Water-to-Water produces safe drinking water at the lowest cost per litre. The Air-to-Water unit uses a turbine that pushes air through a heat exchanger. In the heat exchanger, air is cooled and condensation takes place. The optimised cooling-heating cycle allows efficient energy consumption for higher water production. The collected water is purified and disinfected to ensure the highest drinking water standards. Although this technology is designed to be powered by renewable energy, it can also be powered by traditional energy sources. Based on the ambient temperature and humidity, a single Air-to-Water unit can produce up to 5,000 litres of water per day and can be easily scaled to meet the required water demand. To ensure efficient water production, Rainmaker has developed an adaptive control system that maximises water production depending on the environmental condition at the deployment site.

The Water-to-Water system can be efficiently powered by wind, solar, grid, generator or combinations of these.

Water-to-Water solution

Based on an emerging membrane distillation technology, Water-to-Water is a seawater desalination system in which water is evaporated under low pressure by a heat pump condensation process. The vapour produced by this heating process diffuses through a microporous hydrophobic membrane and all impurities remain in the source water. The driving force of this technology is the partial pressure difference (temperature difference) between each side of the membrane pores.


Project resultaat

JUMO industriële sensortechnologie

Voor hun EU-project met Water-to-Water technologie op Gran Canaria zocht Rainmaker naar de juiste sensoren. Er werden verschillende sensoren geïmplementeerd om de duurzaamheid van het systeem te bewaken en de veiligheid van de installatie te garanderen. Omdat de W2W een ontziltingsinstallatie is, moest de corrosiebescherming worden gegarandeerd. JUMO heeft een uitgebreide selectie van sensoren en automatiseringsapparatuur die geschikt zijn voor waterbehandeling. Voor de W2W unit heeft Rainmaker gebruik gemaakt van JUMO meettechniek. Voor geleidbaarheidsmeetsensoren uit de JUMO Blackline serie en transducers uit de JUMO ecoTRANS serie zijn deze geïmplementeerd. Deze apparatuur wordt gebruikt voor een nauwkeurige geleidbaarheidsmeting die de kwaliteit van schoon drinkwater garandeert. Voor de meting van de geleidbaarheid aan de afvalwaterzijde heeft Rainmaker gekozen voor de JUMO CTI-500. Deze sensor is uitermate geschikt voor hoge geleidbaarheidswaarden omdat dit een inductieve meting is. De MIDAS C18 SW-sensor van JUMO wordt gebruikt om de druk aan de vuilwaterzijde te controleren. Dit is een titanium sensor die zeer geschikt is voor water met een hoog zoutgehalte.

Het Water-to-Water systeem kan efficiënt worden aangedreven door wind, zon, net, generator of combinaties daarvan. Hierdoor kan het water nu op de plaats van gebruik worden geproduceerd, waardoor de transporten distributiekosten worden geëlimineerd. Water-to-Water-units zijn verkrijgbaar in drie maten en produceren 37.500, 75.000 of 150.000 liter drinkwater per dag.
