  • Case study - Even during the cold period I turn off heating at day 13!

    Two years ago Mr. Piljan from Boljevci in Serbia bought a DACS ventilation system for one of his existing 4 houses. The aim was to find out which ventilation system to choose for his new houses that he was about to build. - I cannot say that I was dissatisfied as such with the existing ventilation system as what I had was a system similar to that of all my colleagues: minimum/medium ventilation ...

  • Air Separation Plants and the Use of Oxygen Monitors

    Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is ...

  • Commercial boost for firms that suck carbon from air

    It has long been regarded as one of the more blue-skies solutions to climate change. Now two companies have vastly increased their capability to suck carbon dioxide from the air. One, based in Canada, plans to convert captured CO2 into diesel to fuel buses; the other, in Switzerland, will sell it on to a firm that uses CO2 to boost crop growth in greenhouses. The ...

  • Flotation of algae for water reuse and biomass production: role of zeta potential and surfactant to separate algal particles

    The effect of chemical coagulation and biological auto-flocculation relative to zeta potential was examined to compare flotation and sedimentation separation processes for algae harvesting. Experiments revealed that microalgae separation is related to auto-flocculation of Anabaena spp. and requires chemical coagulation for the whole period of microalgae cultivation. In addition, microalgae ...
