Contamination control is the generic term for all activities aiming to control the existence, growth and proliferation of contamination in certain areas. Contamination control may refer to the atmosphere as well as to surfaces, to particulate matter as well as to microbes and to contamination prevention as well as to decontamination.
Decontamination (sometimes abbreviated as decon, dcon, or decontam) is the process of removing contaminants on an object or area, including chemicals, micro-organisms, and/or radioactive substances. This may be achieved by chemical reaction , disinfection , and/or physical removal.
Water purification combines a number of methods to produce potable or drinking water. Downstream processing refers to purification of chemicals, pharmaceuticals and food ingredients produced by fermentation or synthesized by plant and animal tissues, for example antibiotics, citric acid, vitamin E, and insulin.
The history of water purification includes a wide variety of methods. The methods used include physical processes such as filtration , sedimentation , and distillation ; biological processes such as slow sand filters or biologically active carbon ; chemical processes such as flocculation and chlorination ; and the use of electromagnetic ...
Dry decontamination is a method of removing contaminants (such as chemicals, biological particles, or other liquids, gasses, or solids) without the need to use water or other liquids. Decontamination is an essential duty of hazmat responders as it protects victims from harmful reactions to the contaminants.
Ultrasonic cleaning uses cavitation bubbles induced by high-frequency pressure (sound) waves to agitate a liquid. The agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass, rubber, and ceramics.
An effluent decontamination system (EDS) is a device, or suite of devices, designed to decontaminate or sterilise biologically active or biohazardous materials in fluid and liquid waste material.
The BMBL is an advisory document providing national recommendations for Biosafety Levels, Containment, Decontamination and Disinfection, Transportation, and Disposal of biohazardous agents. [ 10 ] In Canada the government publication "Laboratory biosafety guidelines" was current between 1990 and 2013, [ 11 ] [ 12 ] and has been superseded by ...
