UVTA(TM) UV Technology
Advantage
 

Alternative UV Technology
Disadvantage
 

Non use of fragile quartz sleeves.
 

Use fragile quartz sleeve.

UV chamber consists of non-wettable, virtually non-fouling AFP*.
 

UV chamber uses quartz, which is negatively charged and very susceptible to fouling.
 

In situ UVTA(TM) "Autoklyn(TM)", non-chemical, non-scraping system. Autoklyn is available as an option in larger units.
 

Use of quartz means using corrosive acids and scraping devices.

Control of UV lamp temperature.
 

No control of critical UV lamp temperature.
 

Low maintenance.
 

High maintenance.
 

Ease of operations.
 

Complex operations.

No short-circuiting.
 

Short-circuiting will occur.
 

No critical effluent levels.
 

Level of effluent in the channel is critical.
 

Static flow will not damage the UV lamps.
 

Severe damage will occur if effluent flow slows or stops whilst UV lamps still alight.
 

Low electrical power consumption.
 

High power consumption.
 

Use of high intensity "XUV", low pressure, UV Mercury Vapour Lamps operating 48°C to 55°C.
 

Use of expensive medium pressure UV Lamps operating > 400°C.
 

Lowest time period to change a UV lamp (less than 1 minute) and is uncomplicated - the lamp is low cost.
 

Labour intensive and expensive.

No solarizing of AFP tube in UVTA(TM) UV chamber.
 

Quartz is solarized by the UV light at 253.7 nm wavelength, causing the quartz sleeve to become opaque and require replacement periodically.
 

Guaranteed kill rates with lower UV dosages due to effective design.
 

Requires consistent UV overdosing to try and provide UV dose required.
 

Proudly Australian designed and built.
 

Most other UV systems for effluent and water disinfection are foreign imports.
