FloGard+PLUS - Multipurpose Catch Basin Insert Filter Brochure

FEATURES• Easy to install, inspect and maintain• Can be retrofitted to existing drain catch basins – or used in new projects• Economical and efficient• Catches pollutants where they are easiest to catch (at the inlet)• No standing water – minimizes vector, bacteria and odor problems• Can be incorporated as part of a “Treatment Train”BENEFITS• Lower installation, inspection and maintenance costs • Versatile installation applications • Higher return on investment • Allows for installation on small and confined sites • Minimizes vector, bacteria and odor problems • Allows user to target specific pollutants FloGard®+PLUS Catch Basin Insert FilterCatch Basin Insert FilterGENERAL FILTER CONFIGURATIONFloGard®+PLUS catch basin insert filter shall provide solids filtration through a filter screen or filter liner, and hydrocarbon capture shall be effected using a non-leaching absorbent material contained in a pouch or similar removable restraint. Hydrocarbon absorbent shall not be placed at an exposed location at the entry to the filter that would allow blinding by debris and sediment without provision for self-cleaning in operation.Filter shall conform to the dimensions of the inlet in which it is applied, allow removal and replacement of all internal components, and allow complete inspection and cleaning in the field.FLOW CAPACITYFilter shall provide two internal high-flow bypass locations that in total exceed the inlet peak flow capacity. Filter shall provide filtered flow capacity in excess of the required “first flush” treatment flow. Unit shall not impede flow into or through the catch basin when properly sized and installed.MATERIALSFilter support frame shall be constructed of type 304 stainless steel. Filter screen, when used in place of filter liner, shall be type 304 or 316 stainless steel, with an apparent opening size of not less than 4 U.S. mesh. Filter liner, when used in place of filter screen, shall be woven polypropylene geotextile fabric liner with an apparent opening size (AOS) of not less than 40 U.S. mesh as determined by ASTM D 4751. Filter liner shall include a support basket of polypropylene geogrid with stainless steel cable reinforcement.Filter frame shall be rated at a minimum 25-year service life. All other materials, with the exception of the hydrocarbon absorbent, shall have a rated service life in excess of 2 years.FloGard®+PLUS TEST RESULTS SUMMARYTesting Agency % TSS Removal % Oil and Grease Removal % PAH RemovalUCLA 80 70 to 80U of AucklandTonking & Taylor Ltd. 78 to 95(for city of Auckland)U of Hawaii(for city of Honolulu) 80 20 to 40I n n o v a t i v e s t o r m w a t e r m a n a g e m e n t p r o d u c t sKriStar Enterprises, Inc. 360 Sutton Place Santa Rosa, CA 95407 PH: 800-579-8819 FAX: 707-524-8186www.kristar.com © 2004-2009 KriStar Enterprises, Inc.

Filter shall capture at least 70% of oil and grease and 40% of total phosphorus (TP) associated with organic debris from treated flow. Unit shall provide for isolation of trapped pollutants, including debris, sediments, and floatable trash and hydrocarbons, from bypass flow such that re-suspension and loss of pollutants is minimized during peak flow events.FloGard®+PLUS COMPETITIVE FEATURE COMPARISONFloGard+PLUSFlat GrateFloGard+PLUS Combination InletFloGard+PLUS Round Gated InletEvaluation of FloGard+PLUS Units (Based on flow-comparable units) (Scale 1-10, 10 being best) FloGard+PLUS Other Insert Filter Types** Flow Rate 10 7 Removal Efficiency* 80% 45%Capacity – Sludge and Oil 7 7Service Life 10 3Installation – Ease of Handling / Installation 8 6 Ease of Inspections & Maintenance 7 7 Value 10 2*approximate, based on field sediment removal testing in urban street application **average Long-Term Cost Comparison (Scale 1-10, 10 being lowest cost, higher number being best) FloGard+PLUS Other Insert Filter TypesUnit cost — initial ($/cfs treated) 10 4Installation cost ($/cfs treated) 10 7Adsorbent replacement (annual avg $/cfs treated) 10 2 Unit materials replacement (annual avg $/cfs treated) 10 10Maintenance cost (annual avg $/cfs treated) 10 7 Total first yr ($/cfs treated) 10 5 Total Annual Avg ($/cfs treated, avg over 20 yrs)* 10 5 *assumes 3% annual inflation Catch Basin Insert FilterI n n o v a t i v e s t o r m w a t e r m a n a g e m e n t p r o d u c t sCaptured debris from FloGard+PLUS, Dana Point, CA
