natural water filtration systems puur zuiveren by lukas jager

‘puur zuiveren’ – natural water filtration systems by lukas jager




the process of water purification usually requires a tenuous amount of labour – pre-treatment screenings and chlorination, pH adjustments, and disinfection being a few of the formal approaches of achieving clean H2O. as this takes time and resources, dutch designer lukas jager has developed a purification system that bypasses the un-natural methods of distilling water.

conceived as a series of bowls, his project ‘puur zuiveren’ demonstrates the liquid transition from ‘turbid to clear’. using a mix of clay and fine sawdust heated in an oven at 850 degrees celsius, the material retains a porous characteristic, making it ideal for purifying liquids at a faster rate. by adding colloidal silver, remaining traces of bacteria are killed, extending the shelf life of the final product. with five different types of sawdust density used in each of the objects, water is able to seep through at variable speeds.

  • What\’s the brown/black stuff at the bottom?

  • it looks as though over time the exposure of the plies of wood to the water saturated vessel would result in some nasty delamination but I like the form and basic functional concept

  • Not very new. Variations of these things are sold all over the third world. It may act as a “filter” for small particles, so the water will LOOK cleaner. However bacteria are very small (0.45 micron) and will pass right through. Thus the addition of colloidal silver – very dangerous substitute for chlorine (Google argyria or colloidal silver risk).

    Better stick to design and leave drinking water safety to the pros.

  • Excxiting that they’ve come up with a faster way to purify water. But How does one collect the purified water once it comes through the ‘bowl’? It seems the actual collection of the water should be part of the design, no?

  • Thanks, AllenC

    what is wrong with artificial/un-natural methods ? I get that they can be costly and demand serious upkeep and technical know-how, but the article gives off the idea that the designer has too many irons in the fire.

    Defending “artisan” methods AND promoting water purity in the world ? A smorgasbord for the self righteous ?

    If I come off as too sarcastic, my apologies, but for reasons stated by AllenC this just looks like a shameless attempt to grab a few ovations in a climatte of perpetual urgency. I, for one, would rather applaud the efforts of Project H
