PORTSMOUTH, UK - British ultraviolet (UV) disinfection system provider atg UV Technology has been awarded a contract by Trant Engineering to supply utility Portsmouth Water with its first installation.
The contract covers supply and installation of UV units for Cryptosporidium inactivation at two water treatment works: Eastergate and Westergate.
Both are 20,000 m3/day borehole works and each site will be provided with fully automatic duty and standby UV reactors. The contract is due for completion by mid-2017.
The reactors, which are third party validated to US EPA UVDGM, feature atg UV’s multi-lamp 800 Watt Amalgam UV lamps.
The required 4-log inactivation of Cryptosporidium will be achieved by a validated UV dose of 40 mJ/cm2 and this will be maintained over the full range of works flow by monitoring UV intensity in each reactor and automatically adjusting the dose.
The atg UV UVLW range uses Amalgam UV Lamp technology and in-line, L-shaped UV reactors.
