Stormwater Tidbits – A Public Education Series Part 2: Loving Your Car and the River Too!

By: Imbrium Systems
Nearly everybody remembers the very first car they owned. The reasons vary. For some it was a rite of passage into adulthood, the first real taste of independence from Mom and Dad. Perhaps it was the coveted reward of much hard work at a minimum-wage job and scrupulous saving, and being able to proudly say “I bought it, it’s mine!” It may have produced the liberating thought...

Stormwater Filtration: A Tail(water)-End Discussion

By: Jordan Kahlenberg – Sr. Stormwater Design Engineer
When designing a stormwater filtration system the two most common design constraints are treatment flow rate and sediment loading. In other words, how much flow can it filter/treat, and how much sediment (i.e. Total Suspended Solids, TSS) can it remove before maintenance is required? Both of these parameters are important to the design of a stormwater filtration system, but there is a third import...

Stormwater Tidbits – A Public Education Series. Part 1: Doo-Doo No-No

By: Joel Garbon
We’ve all seen it plenty of times. Maybe while we are picnicking with our family, taking a stroll in a city park, and simply looking out a window into the neighborhood. Something draws our attention to a person walking their dog. The person stops as their pet sniffs the grass anxiously. The dog assumes the familiar defecation position, and the owner suddenly appears distracted by a compellin...

Jellyfish Filter Field Testing Performance in Australia

By: Imbrium Systems
In 2010 & 2011 the Jellyfish Filter was TARP field tested over a duration of 25 storm events adhering to New Jersey Department of Environmental Protection (NJDEP) amended TARP field monitoring protocol. Additional field testing is ongoing on a JF4 (1200 mm diameter) unit providing treatment of a commercial site in Ispwich, Australia, which is a suburb of Brisbane. The monitored catchment&rsquo...

Filter Sizing: Considerations for Sediment Mass Loading & Longevity

By: Ben Farrell - Imbrium Stormwater Design Engineer
Sediment (TSS) in urban stormwater runoff causes many water quality, habitat and aesthetic problems in our waterways. Various pollutants of concern, such as metals, nutrients, hydrocarbons, and bacteria, are typically adsorbed onto the sediment particles. Filtration devices are often used to greatly reduce the pollutant loads in runoff. When sizing a filter it is important to consider both the wat...

Comparing Treatment Performance of Oil-Grit Separators and Stormwater Filtration Devices

By: Joel Garbon – Regulatory Manager
Oil-grit separators (OGS) have a decades-long history of use in Canada as primary treatment devices for reducing pollutant loads in stormwater runoff. OGS devices are typically utilized to capture gross pollutants, particulates (TSS), and oil. The dominant treatment mechanisms within OGS devices are sedimentation and floatation, with each functioning on the principle of gravity-based separation. P...

The Importance in Scaling of OGS Devices

By: Jordan Kahlenberg – Sr. Stormwater Design Engineer
As a Sr. Design Engineer with Imbrium Systems, I receive questions every day regarding projects which include specifications for Oil Grit Separator (OGS) devices. Often these questions stem from having to meet a project’s specifications and requirements for pollutant removal performance. In order to provide the best solution, I require great detail about how the device is required to opera...

Particle Size Distribution (PSD) - Importance of Specific Gravity

By: Ben Farrell - Imbrium Stormwater Design Engineer
Pollutant removal in stormwater exhibits a distribution of settling velocities, which is a reflection of the complex mixture of transported total suspended solids (TSS). The TSS mixture creates a settling distribution due to the different particle sizes, shapes, temperature, and specific gravities. Solids can be further categorized by type: organic, inorganic, biological, and chemical. The spe...
