The secondary effluent is combined into a single channel containing a Trojan UV3000
Plus disinfection system. The UV system consists of two banks of horizontal lamps,
each having 8 lamps. The TrojanUV3000Plus™ uses energy-efficient amalgam lamps.
These high output lamps are automatically dimmed when flow demand drops or when
the water quality changes. The system uses ActiClean™ during cleaning cycles, which eliminates sleeve fouling.
Permit limits and actual average results for the Moundsville facility after 23 years of
operation are shown below.
