  • Flotation separation of strontium via phosphate precipitation

    Flotation separation of strontium (Sr) from wastewater via phosphate precipitation was investigated. While 37.33% of Sr precipitated at highly alkaline pH in the absence of PO43−, it completely precipitated as Sr3(PO4)2 at a molar ratio ([PO43−]:[Sr2+]) of 0.62 at a lower pH value. The presence of Ca2+ hindered ...

  • CO2 Capture from Ambient Air by Crystallization with a Guanidine Sorbent

    Carbon capture and storage is an important strategy for stabilizing the increasing concentration of atmospheric CO2 and the global temperature. A possible approach toward reversing this trend and decreasing the atmospheric CO2 concentration is to remove the CO2 directly from air (direct air capture). Herein we report a simple aqueous guanidine sorbent that captures ...

  • Air Pollution Is Making Office Workers Less Productive

    Businesses invest a great deal of time and money in interventions that claim to increase workers’ productivity through on-the-job training, new protocols, advice from consultants, and so on. Recent research suggests that there’s a surprising input into productivity that no one ever thinks about: clean air. We all know that air pollution is bad for our health, and researchers ...

  • 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 ...

  • Case study - Daphne utilities water reclamation facility

    With significant TSS and BOD reductions from their Salsnes Filter system, Daphne Utilities has restored previously lost plant capacity. More than that, loading reductions have cut back aerator maintenance and lowered energy consumption of blowers. Project Background Daphne Utilities, situated on the eastern shore of Mobile Bay in Alabama, provides water, sewer and natural ...

  • The role of innovative technologies in achieving energy-neutral wastewater treatment

    A new flowsheet is proposed to achieve energy-neutral wastewater treatment (even better, electricity-neutral) while removing nitrogen using the proven nitrification-denitrification metabolic pathway. It is compatible with solid-liquid separation by conventional clarification or membrane filtration. The new flowsheet is based on a hybrid membrane-aerated biofilm reactor process which uses ...

  • 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 ...

  • PSA Technology hits the Fast Lane

    Conventional pressure-swing adsorption (PSA) has been used ito separate and purify industrial gases for more than 35 years. The technology, first developed by ExxonMobil and Air Liquide in the late 1950s, is based upon the capacity of adsorbents to selectively adsorb and desorb particular gases as gas pressure is raised and lowered. PSA is currently used in applications ranging from the ...
