STRUCTURAL BMP BF-1 BIOFILTRATION . Biofiltration . facilities are vegetated surface water systems that filter water through vegetation, and soil or engineered media prior to discharge via underdrain or overflow to the downstream conveyance system. Biofiltration facilities have limited or no infiltration. They are typically designed to provide ...

Vegetated banks provide a biofilter to remove some sediment and improve basin performance. Infiltration trenches are relatively unobtrusive BMPs, as they have a small, narrow footprint and are flush with the ground. This BMP is well suited for small drainage areas, and integrates well into site layouts with placement near parking areas and in ...

Biofiltration can reduce odor and hydrogen sulfide emissions from livestock facilities by as much as 95% and ammonia by 65% (Nicolai & Janni, 2000) This method of odor control has been shown to be both economical and effective in swine raising systems. Biofilters are most easily adapted to mechanically ventilated buildings or on the pit fans of naturally ventilated buildings. …
Vegetated Biofilter Design January 18, 2019 | Agency This presentation covers the design of vegetated biofilters, including treatment goals, siting analysis, sizing, and other considerations.
As with any infiltration BMP, groundwater mounding impacts must be assessed, as required by N.J.A.C. 7:8-5.2(h). This includes an analysis of the reduction in permeability rate when groundwater mounding is present to confirm the system will drain within 72 hours after the precipitation stops.
Biofilters are an odor treatment technology that utilizes biological processes as the treatment mechanism like biotrickling scrubbers. Biofiltration utilizes naturally concurring microorganisms that grow on media to oxidize odor and air emission compounds to carbon dioxide, water, biomass, and other benign by-products such as chloride and sulfate.
Post construction storm water BMP design guidance is found in the Location and Design Manual, Volume 2. Post construction storm water BMP design support is available through the Office of Hydraulics by contacting Becky Humphreys. The below documents are provided to supplement the information found in the Location and Design Manual.
Equation 2. Biofilter media volume (m 3) = TAN production (g TAN/day) ÷. VTR (g TAN/m 3 /day) We can use this equation to calculate the volume of media a trickling filter would need as: 2,300 g TAN/day ÷ 90 g TAN removed/m 3 /day = 25 m 3. If this trickling filter were sized at 2.5 m square, the media height would be 4.0 m.

Cost Considerations. Cost includes the initial construction of the biofilter, added fan operational cost, rodent control and moisture control. Estimates for initial construction range from $0.062 per cfm treated (1998) to $0.25 per cfm treated (2004). Operating costs were estimated from $0.005 to $0.015 per cfm treated.
Bypass high flows, or control release rates into the biofilter, if necessary. Install level spreaders (min. 1-inch gravel) at the head and every 50 feet in swales of ≥4 feet width. Include sediment cleanouts (, settling basin, or equivalent) at the head of the biofilter as needed. Use energy dissipators (riprap) for increased downslopes.
Bioinfiltration (bioretention with underdrain) Landscaped shallow depressions that normally consist of a ponding area, mulch layer, planting soils, plants, and collection pipes in a gravel layer to capture and filter stormwater runoff. A detailed description of this BMP type can be found in the BIO-1 Fact sheet in the 2017 Technical Guidance ...

Abstract The International Best Management Practices Database is a searchable, online database that provides access to best management practice (BMP) performance data in a standardized format for roughly 200 BMP studies.
1. The USDA Natural Resources Conservation Service (NRCS) methodology, including the NRCS Runoff Equation and Dimensionless Unit Hydrograph as described in Chapters 7, 9, 10, 15 and 16, Part 630 Hydrology, National Engineering Handbook (NEH), may be used for the computation of runoff volume, peak flow rate of runoff and hydrograph of runoff resulting from specific
A Ventura Countywide Unified Storm Drain System Map is now available! The map was created by mapping natural and engineered drainage system linkages using available topographic information, construction record drawings, and other sources and combining it with existing storm drain data. What's the big deal about runoff? Runoff carries pollutants.
Based on past experiences with zero-exchange marine shrimp systems, it was decided to explore the impacts of adding carbohydrate such as sugar to the system to reduce the ammonia-nitrogen loading on the biofilter. Four treatments were tried over several days: 50, 100, 150 and finally 200 percent of the daily feed rate was added as sugar.
Biofilter. A biofilter was a scanning device that analyzed an incoming transporter matter stream for known biological anomalies. When it detected such anomalies, like viruses, it attempted to remove them from the stream.The transporter operator was always warned of detected anomalies whether or not they were able to be removed. Of note, microbes that existed as both matter …
Biofilter/Bioeretention Area Biofilters, often referred to as rain gardens, are landscape features that store and treat stormwater runoff. Surface runoff is directed into shallow, vegetated depressions with underlying layers of soil, sand, and gravel. They may have an underdrain that sends excess runoff to the storm sewer.
