ULTRAAQUA · UV DISINFECTION FOR LOW-TRANSMITTANCE WATER
LOW UVT Series
UV systems with SWIRLFLOW™ hydraulics for wastewater, reuse water and other water with low UV transmittance.
Pricing on request.
Overview
Turbid or coloured water, as found in wastewater treatment, absorbs much of the UV light, and a standard reactor can leave poorly irradiated zones. The LOW UVT series is designed for exactly these conditions, in municipal and industrial secondary treatment and reuse applications.
Its SWIRLFLOW™ hydraulics lengthen the time pathogens spend in the UV field and remove the dark areas where untreated organisms could pass, while energy demand stays low.
Ozone UV Solutions supplies LOW UVT systems as an authorised ULTRAAQUA reseller and supports them locally: from sizing and installation through commissioning, servicing, lamps and spare parts.
Key features
- SWIRLFLOW™ hydraulic design for even UV exposure without dark zones
- Electropolished SS316L reactor [Super Duplex], design pressure 10 bar [16 bar]; 6 bar [10 bar] on MR44 and MR56
- ULTRATHERM 350 W low-pressure high-output amalgam lamps with a rated life of 16,000 hours
- Sizes from 1 to 56 lamps with flanged connections from DN100 to DN500
- ÖNORM M5873 certified UV intensity sensor and automatic ULTRADOSE dose pacing (50–100%)
- Automatic ULTRAWIPER™ cleaning and PLC with 7" ULTRATOUCH touchscreen on models with four or more lamps
Typical applications
- Municipal and industrial wastewater, including secondary treatment and reuse
- Stormwater overflow (CSO) and landfill leachate
- Cooling tower water, oil and gas, and horticulture
