  • Chemistries of Ozone for Municipal Pool and Spa Water Treatment

    Ozone generated by ultraviolet (UV) radiation is used in North America for treating (mostly residential) spa and pool waters almost exclusively, while only a handful of North American municipal pools and spas are using ozone generated by corona discharge technology in accordance with well–established German teachings. On the other hand, several thousand European municipal swimming pools and ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...

  • Profile of Ozone/Bromine Sanitation Systems for City of Tucson Municipal Pools

    Due to the inherent risks associated with the use of chlorine gas as a sanitizer for the City of Tucson’s twenty-six municipal swimming pool sites, I found myself in search of an alternative water sanitation method. The challenge was clear; find a system that would be safer to manage than gas chlorine, yet yield the same favorable sanitation and water quality results. Since all the sites ...

  • Sanitation Using Ozone & Chlorine

    For nearly 100 years, ozone has been used all over the world for water sanitation. It is nature’s strongest oxidizer and has a byproduct of pure oxygen. Chlorine, on the other hand, is a very effective, time-proven chemical, but is ineffective against hard-to-kill microorganisms such as cryptosporidium. It also has some unpleasant byproducts. Together, however, these two substances can ...

  • Indoor Air Quality and Hazardous Gas Detection

    Indoor air contaminants come in a variety of forms and originate from multiple sources. Interactions between building materials and furnishings, activities and equipment inside the building, internal temperature and relative humidity, filtration and ventilation system operations, climate and building occupants all contribute to the indoor air quality (IAQ) in commercial, industrial, residential ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • It`s Hot in the Y.M.C.A

    The Montclair Y.M.C.A in New Jersey, America has two swimming pools and shower facilities that require constant hot water - presenting a big challenge to the management and maintenance teams. With such a demand on the heat exchangers, limescale build-up has been a perennial problem, not only does it increase fuel usage, but if left unchecked could result in equipment failure. The centre ...

  • Harnessing the Sun`s Energy for Water and Space Heating

    The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...

  • On rooftops worldwide, a solar water heating revolution

    The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm ...

  • Wastewater Mining and Reuse: Creating Benign Future Scenarios

    Wastewater mining: In addition to being perhaps the most uninviting combination of words, it sounds like a most unlikely idea. But for almost 30 years, Aqueonics, now headquartered in Greenville, SC, has pioneered such systems, starting in the ’80s, with its first wastewater mining project. For that project, Aqueonics provided an onsite or decentralized treatment system for a developer in ...

  • Home, Sweet Wastewater Building

    How can a wastewater treatment plant embedded into a neighborhood not use much landmass and be environmentally friendly and user-friendly all at the same time? One system aims to do all of the above. Why should a wastewater treatment plant always have to look like, well, a wastewater treatment plant?  A visual trip through project files of Aqueonics Inc., based in Greenville, SC, reveals photos ...

  • What will it take to get plastics out of the ocean?

    From drones to filters to artificial islands, innovators are working to reduce the threat thousands of tons of trash pose to marine ecosystems. A few palm trees stand strong in the salty breeze. Located on the southern tip of the Pacific island chain of Hawaii, Kamilo Beach is an isolated stretch of black volcanic shoreline in the middle of nowhere. Just a few hundred yards ...

  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...
