ROCKVILLE, MD, July 28, 2011 /PRNewswire/ – When the residents of Flathead Lake
in northwest Montana sought solutions to untreated stormwater entering
the Lake at Bigfork Bay, they turned to Imbrium™ Systems’ treatment
technologies to provide engineered Stormwater solutions.
Unfortunately, water quality at Flathead Lake has gradually declined
over recent decades as the human footprint within the basin region
increased. Since Montana listed Flathead Lake as an impaired water
body, local residents were determined to improve Flathead Lake’s water
quality in order to preserve its fishing, boating and recreational
opportunities in addition to protecting the aquatic life and ecosystem
from harmful sediment and nutrients. The Montana Department of
Environmental Quality (DEQ) plan to restore Flathead Lake sets water
quality targets, including a 15% reduction in nitrogen and phosphorus
loads.

Imbrium Systems’ Regional Manager, Corky Lambert, worked with civil
engineer, Brett Walcheck, P.E., from 48 North P.C. – an engineering
firm in Kalispell, Montana – to design a workable stormwater treatment
solution. “It was terribly important that the water quality of
Flathead Lake be improved for generations to come”, noted Corky
Lambert. “That’s why we designed a treatment train approach for
Stormwater runoff that included a Stormceptor STC 900, Imbrium System’s
premier hydrodynamic oil and sediment separator, ahead of the Jellyfish
Filter which captures fine sediment down to 2 microns along with
nutrients like phosphorus, nitrogen as well as heavy metals. This
engineered approach allowed the locality to provide maximum Stormwater
treatment for the roadway improvements along Grand Drive”, stated
Lambert.

In addition, Lambert noted that much credit for navigating the
bureaucratic shoals and securing project funding from the Montana
Departments of Commerce, Environmental Quality and Natural Resources
and Conservation should be given to Debbie Pierson from Flathead County
and the Bigfork Stormwater Advisory Committee, chaired by Sue Hanson.

As part of the Flathead Lake Stormwater treatment train, the Stormceptor
STC 900 was installed to capture floatable trash, sediment and
hydrocarbons before they entered the Lake. With nearly 40,000
Stormceptor installations world wide, it has earned a well-deserved
reputation as the most effective and easily maintained hydrodynamic
Stormwater treatment device.

Brett Walcheck of civil engineering firm 48 North P.C. noted that
“During our evaluation process of Stormwater treatment devices, we felt
that the products offered by Imbrium were the most effective at helping
us reach our Stormwater treatment goals. The superior pollutant
capturing capabilities and the realistic maintenance aspects were
crucial in our decision process. We believe that our stringent
requirements will be far exceeded by the implementation of both the
Stormceptor and Jellyfish Filter systems.”

The water quality of Flathead Lake continues to be threatened by
nutrient pollution from Stormwater runoff. The Jellyfish Filter,
however, has undergone a rigorous TARP (Technical Acceptance and
Reciprocity Partnership) field testing that has clearly demonstrated
that the Jellyfish Filter removes 85% TSS (Total Suspended Solids), 60%
Total Phosphorus (TP) and 50% Total Nitrogen (TN).

“Since the Jellyfish Filter requires only 18-inches of “head” or drop to
fully operate the system, it works like a charm. It is an innovative,
membrane filter system that is both compact, easily maintained and
allows for a high treatment flow rate. Its lightweight cartridges
weigh only 20 lbs. dry and 50 lbs. wet. They are back-washable,
reusable and easily replaceable. Conventional granular media
cartridges in Stormwater filter systems can easily weigh well over 250
lbs. when wet and require heavy lifting equipment. The Jellyfish
Filter is a “maintenance friendly” Stormwater technology”‘ noted
Imbrium Systems’ Corky Lambert.
