C.I.Agent Solutions offers a variety of sludge and dewatering systems to help manage your Vault and Manhole Maintenance.
There is an estimated 5 million utility vaults and manholes in the United States – approximately 4 manholes to every one vault – and all of them present dewatering challenges.
Water runoff trapped in these underground structures may have traces of oil, lubricant, or other hydrocarbons, as well as organic matter, mud, silt, or other pollutants coming from the surface. The water accumulates in these substructures and is usually discharged by some sort of submersible pump system. What dewatering pump systems can’t handle is the debris, sediment and light oils also in the structure.
EVAC Filtration System
The C.I.Agent EVAC Filtration System and line of products is ideal for dewatering contaminated water from underground utility vaults, manholes, retention and secondary containment vessels, out-fall on oil-water separators and elevator shafts.
C.I.Agent EVAC Filtration Dewatering System
It utilizes a 4-layer state-of-the-art filtration and dewatering technology to absorb hydrocarbons, remove large and fine sediment, and polish the water. The integrated use of the oil-solidifying C.I.Agent Polymers micro encapsulates oil in order to give the EVAC Filter the highest available hydrocarbon capacity in the industry. It also eliminates the need for vacuum trucks and expensive water processing.
Its superior engineering allows the EVAC Filter to endure not only high flows but also higher pressures. A Hydrocarbon Detection Strip indicates when the filter is nearing maximum hydrocarbon retention level. Other dewatering systems available include the EVAC Lite and the EVAC Lite Plus.
Hydrocarbon Detection Strips
The C.I.Agent® Hydrocarbon Detection Strips can quickly and accurately determine the presence of any type of oil in water. When introduced into a potential hydrocarbon situation, the light blue color of the strip changes to a darker blue if hydrocarbons are detected.
C.I.Agent Hydrocarbon Detection Strips
The size and color intensity of the darker areas indicate the quantity of oil detected. If no oil present, the strip will not moisten or discolor.
Hydrocarbon Detection Strips can be used in any situation where there is a need to detect oil contamination in water, including in elevator shafts, underground utility vaults and manholes, retention and secondary containment vessels, and out-fall on oil-water separators prior to pumping out water.
Vault Sump Filters
The C.I.Agent VSF Vault Sump Filters complement any pump system by preventing debris, silt, and oil from reaching the pump, thus avoiding malfunction and stoppage.
C.I.Agent VSF Vault Sump Filters
The dewatering VSFs are available in round configuration and in segmented panels for flexibility to fit in any area. Complete VSF Systems include the Filter Housing, the VSF Pre-Filter (Debris and Silt Filter), and the Agent-Q Oil and Sheen Filter. Components can be ordered together as a system or separately, depending on your needs. VSF Add-Ons include an installation kit and a rubber seal.
The C.I.Agent Vault Integrated Pump and Oil Redundancy (VIPOR) System is an automatic vault / manhole sump pump that can be run with the confidence that sludge, sediment, & oil will not be discharged.
C.I.Agent VIPOR System
The VIPOR System’s main core provides complete shutoff in the event of a significant hydrocarbon release. This is made possible by the use of C.I.Agent Solidifying Polymers that capture, contain and solidify harmful hydrocarbons.
Three VIPOR models are available based on your site-specific application. Use the VIPOR-SOWF (Sump Oil Water Filtration) in secondary containment vaults with a collection sump. The versatile VIPOR-100 SOWF features a flow rate of over 100 gallons per minute and does not require a sump or crock to operate. The VIPOR-SUMP behaves as an oil-water separator, and is generally installed in transformer vaults with a flat floor and a crock.
