When applied to air filtration and purification, biofilters use microorganisms to remove air pollution. [1] The air flows through a packed bed and the pollutant transfers into a thin biofilm on the surface of the packing material. Microorganisms, including bacteria and fungi are immobilized in the biofilm and degrade the pollutant. Trickling ...
Hydrilla (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, Hydrilla verticillata, though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory ...
There has been a great effort to develop efficient methods for biofilm removal or prevention in clinical and food manufacturing processes. On the other hand, current research suggested that biofilms can be useful for constructive purposes such as a template of new materials [1] [2] that may find applications in the industry. One distinctive ...
The C2DA inhibit methicillin resistant staphylococcus biofilm, but don't eliminate it. The mechanism of the biofilm inhibition by these molecules is still unknown. C2D is a medium of fatty acid chain that effect on staphylococcus aureus biofilm and dispersion of these biofilm. Pseudomonas aeruginosa is the main source for these molecules. [15]
Ultrasonic antifouling is a technology that uses high frequency sound to prevent or reduce biofouling on underwater structures, surfaces, and medium. Ultrasound is just high frequency sound (which humans can not hear).
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
This small secondary clarifier at a rural sewage treatment plant is a typical phase separation mechanism to remove biological solids formed in a suspended growth or fixed-film bioreactor. Secondary treatment (mostly biological wastewater treatment ) is the removal of biodegradable organic matter (in solution or suspension) from sewage or ...
Moving bed biofilm reactors can efficiently treat hospital wastewater and remove pharmaceutical micropollutants. A 2023 study has shown that a strictly anaerobic MBBR, combined with an aerobic biofilm reactor can achieve high removal rates of pharmaceuticals, such as metronidazole, trimethoprim, sulfamethoxazole, and valsartan.
