Uv disinfection system design.
According to malley et al.
2002 many water systems including small systems using ground water not under the influence of surface water will decide that uv disinfection is an attractive alternative.
The uv dose delivered by a reactor is the key parameter used to confirm proper uv system sizing for a specific application.
Wastewater technology fact sheet.
Uv disinfection will not be used solely by systems to meet the requirements of lt2eswtr.
The information required for design is based on using the results of field studies or from collimated beam tests.
As such a true baseline of performance is required to ensure permit requirements are met at the design conditions.
Ultraviolet germicidal irradiation uvgi is a disinfection method that uses short wavelength ultraviolet ultraviolet c or uv c light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their dna leaving them unable to perform vital cellular functions.
The accuracy of data obtained through bioassay validation eliminates any ambiguity in this baseline.
Uvgi is used in a variety of applications such as food air and water purification.
Currently a deterministic approach is used for the design of low pressure uv systems.
Provides information on technologies advantages and disadvantages design criteria operation and maintenance and costs.
In some cases collimated beam tests are used in conjunction with field tests.
