Wet-weather monitoring

HydroFlow from Cenozon is a software application that monitors and automatically notifies pipeline operators of abnormal stream flow conditions associated with their pipeline water and provides critical insight with historical water level records (where available). Combining real-time stream flow data with the user’s pipeline water-crossing data, HydroFlow employs data visualization and geospatial mapping technology to provide a visual snapshot of pipeline crossings and associated water gauges. HydroFlow can be used with the operator’s existing data and risk management system or as part of Cenozon’s Pipeline Integrity Risk Manager software.

Stormwater filtration system

The Zinc-B-Gone® line of stormwater filters from StormwateRx are designed specifically for the removal of dissolved zinc and copper from rooftop stormwater runoff. They easily attach to downspouts and are guaranteed to remove zinc and copper to allowable benchmark levels. The new product comes in two configurations: Zinc-B-Gone Basic for attachment to downspouts and Zinc-B-Gone Pro for monitored installations and large or combined downspouts with more complex water chemistry. For larger, more complex industrial applications, Zinc-B-Gone Pro meets the strictest requirements, removing up to 99.9% of zinc, 99.7% of copper and a multitude of other pollutants.

Cloth media filtration system

The AquaPrime® cloth media filtration system is an effective solution for CSO, SSO and stormwater applications due to its proven removal efficiencies and high-quality effluent, even under varying influent conditions. The AquaPrime system utilizes a disk configuration with three zones of solids removal: a Floatable Zone; a Settled Solids Zone; and a Filtration Zone to effectively filter wet weather flows with or without the use of chemicals. The system is designed to handle a wide range of flows in a fraction of space compared to other treatment methods and offers simple startup/shutdown with unattended operation for remote locations.

Inline check valve

Red Valve’s CheckMate® UltraFlex™ Inline Check Valve. Features a patented “Arc Notch” and optimized construction, opening 40% sooner than other check valves, allowing the pipeline and entire collection system to drain up to 40% faster. Because the UltraFlex “snaps” open with far less head pressure, pipeline capacity is significantly increased, allowing free flow of water during weather events and minimizing the chance for standing water to collect upstream.

Filtration system

In stormwater management systems without pretreatment, sediment and fines can enter an underground detention/retention system and reduce the system’s infiltration capacity by clogging stone surrounding the chambers. CULTEC’s Separator™ Row is designed to trap sediment and/or debris that may pass through the upstream water quality structures and into the chamber system. Captured pollutants are flushed into a sumped access manhole for vacuuming. The process repeats until the Separator Row is completely free of sediment and debris. When installed with CULTEC No. 410 and No. 4800 geotextiles, it will remove at least 80% of suspended sediment at a flow rate of 24 gallons per minute.

Manufactured stormwater treatment device

Oldcastle Precast’s PerkFilter media filtration system and Dual-­Vortex Separator (DVS) are hydrodynamic separators that uses physical treatment processes such as sedimentation, filtration and sorption to remove total suspended solids (TSS), gross solids, trash and debris, and petroleum hydrocarbons from stormwater runoff. Both devices enhance pollutant removal by directing incoming flow to two vortex tubes that operate in parallel.
