Uv Disinfection System Design

The information required for design is based on using the results of field studies or from collimated beam tests.

Uv disinfection system design.

As such a true baseline of performance is required to ensure permit requirements are met at the design conditions. Uv disinfection will not be used solely by systems to meet the requirements of lt2eswtr. 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.

The uv dose delivered by a reactor is the key parameter used to confirm proper uv system sizing for a specific application. We design germicidal uv systems for disinfection of air surfaces water and liquid sugar for industrial commercial municipal and residential applications as well as custom built uv systems. Us epa ow owm industrial branch subject. According to malley et al.

Currently a deterministic approach is used for the design of low pressure uv systems. Uvgi is used in a variety of applications such as food air and water purification. Wastewater technology fact sheet. 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.

In some cases collimated beam tests are used in conjunction with field tests.
