  • The effect of immobilized catalyst structure on the degradation of chemical and biological contaminants in simulated solar photocatalytic water purification

    The performance of different configurations of titanium dioxide-coated foam supports as photocatalysts in an enhanced solar disinfection system for drinking water treatment was evaluated, using the reduction of methylene blue, 1-4-dioxane, and Escherichia coli as performance indicators. Reactors with immobilized catalysts were able to match or surpass the performance of a suspension ...

  • Removal and fate of emerging contaminants combining biological, flocculation and membrane treatments

    An experimental study combining biological treatment with flocculation (F) and ultrafiltration (UF) membrane technology was conducted, separately and in combination, seeking to increase insight into the capability of such treatment processes to remove emerging contaminants (ECs). The occurrence and removal efficiencies of 17 ECs are reported for wastewater from Mexico City. ...

  • ES & E OZONATOR Publication Nov 2011

    Disposal of biohazardous material has long been a serious and costly problem for hospitals, clinics, research institutes, bio-industries, airports, ports and other generators of biohazardous and regulated medical waste. Until now, incineration, heat, steam or dangerous chemicals have been the only way to treat many of these wastes. Not only are these processes costly, but they leave a high carbon ...

  • Distillation treatment and removal of contaminants from drinking water

    Distillation treatment typically removes most of the dissolved materials. In addition, the boiling process kills biological contaminants. Nevertheless, there are certain volatile and semi-volatile organic compounds that may not be removed by distillation (CDPH 2009). Organic compounds that boil at temperatures greater than the boiling point of water (some pesticides) can be effectively removed ...

  • Cleaning and maintenance management march 2002

    While the health risks associated with fluid waste have been known for decades, it wasn’t until the introduction of AIDS into our society that infection control practices and an awareness of the vulnerability to healthcare workers, including custodians, to exposure of bloodborne pathogens, including Heptatities B, became a major concern. Today, a myriad of regulations govern workers’ ...


  • Cleaning & maintenance management

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury’s hidden danger also lies in when at room temperature and exposed, it vaporizes readily. Once it has become an aerosol, it is absorbed into the lungs and ...

  • Florida hospital complex goes green with recycling, biodegradable programs

    For Earth Day 2009, Rob Lester really had something special to celebrate. Just one year after launching a biodegradable project at Florida’s Ocala Regional Medical Center and West Marion Community Hospital, some 1.5 million Styrofoam cups, bowls and plates and plastic utensils are no longer being sent to the landfill. That program has proven so successful that the 200-bed medical center and its ...
