Design consists of packaged high-rate settling, adorption clarification, mixed media filtration and optional UV disinfection
The Trident® HS system is based on Trident® technology (adsorption clarification and filtration). The process consists of tube settling with external sludge recirculation, adsorption clarification, Microfloc® Mixed Media filtration in a single tank with an optional Ultra Violet (UV) disinfection integrated downstream. The addition of tube sedimentation combined with sludge recirculation greatly increases solids removal capacity. The Mixed Media Filter delivers excellent predictable finished water quality. The system also includes the MULTIBLOCK® underdrain with LaserShield™ direct retention air/water backwash underdrain system. UV disinfection can be provided (one per tank). Multi-barrier protection for difficult-to-treat surface water, groundwater, industrial process water, and tertiary wastewater.
