  • Fly Ash Treatment – Plasma Torches versus Graphite Electrodes

    Background Plasma generating devices have to be designed to tolerate incredibly harsh conditions during operation and in particular very high heat loads and temperatures around the arc. However, when used in the vitrification of highly chlorinated materials the challenge is even greater than in other applications. The combination of high ...

  • How to Choose the Right Commercial Air Filter

    When it comes to selecting a commercial air filter, or air filtration system, there are many variables that have to be considered. In general, the choice of which air filter can be made a bit easier by first defining the overall goal that you are trying to achieve which is usually one of two options. Is the purpose of the filter to protect the air circulation equipment, or is it to provide a ...

  • Are Probiotics The Future Of Cleaning?

    Given the choice between a cleaner that reduces germs by 86% and one that all but eliminates them at 99.9%, which one would you choose? If you’re like most people, the answer appears simple – get rid of as many germs as possible. But those nearly 100% effective cleaners aren’t necessarily the best choice. Why? Because they kill all germs, good and bad. Probiotics are ...

  • The Benefits of Green Cleaning

    Did you know that over 100 trillion bacterial cells consider your body their home? It’s true, and they outnumber your regular cells 10 to 1. These tiny guests live in your mouth, nose, and gut and they make up what is known as your microbiome – your highly personalized mini-ecosystem of both good and bad bacteria. The Antibacterial Craze We’ve ...

  • Polarized-Media EACs are coming of Age

    Non-ionizing  polarized media is an IAQ technology finding broader market uses. It applies an active electric field to cap tore airborne particles, changing the way particles, behave in the air. In smaller residential equipment, this allows an electronic air cleaner (EAC) to operate efficiently within a space only 1 inch wide - the same sp-ace as a disposable filter. In larger commercial ...

  • Dynamic Air Quality Solutions - Celebrating Thirty Years!

    This year we are very pleased to celebrate the thirtieth anniversary of the first one-inch polarized-media electronic air cleaner. It was thirty years ago that the first polarized-media electronic air cleaner, produced under our “Dynamic Air Cleaner” brand, was introduced. As with many high-efficiency filtration products, polarized media has its roots in industrial applications. ...

  • Microbial reduction efficiencies of filtration, electrostatic polarization, and UV components of a Germicidal Air Cleaning System

    Abstract: This study determined the effectiveness of components of a germicidal air-cleaning system involving filtration, electrostatic polarization, and UV light on the reduction of airborne bacteria and molds. The filter alone, filter and electrostatic polarization combined, and the filter, electrostatic polarization, and UV light were found to be effective (P < 0.05) in reducing a given ...

  • Forward osmosis membrane fouling and cleaning for wastewater reuse

    Membrane fouling properties and different physical cleaning methods for forward osmosis (FO) and reverse osmosis (RO) laboratory-scale filtration systems were investigated. The membrane fouling, with respect to flux reduction, was lower in FO than in RO when testing an activated sludge effluent. Cross-flow velocity, air-scouring, osmotic backwashing and effect of a spacer were compared to ...

  • Visualized study on the interaction between single bubbles and curved solid surface in flotation separation process

    The present study has been devoted to bubble–curved solid surface interaction in water, which is critical to the separation of suspended particles by air flotation. For this purpose, two particular stages of the interaction (collision and attachment) have been examined visually using high-speed photography in a laboratory-scale flotation column. The effects of the surface material and ...
