biofilter การใช้

• A biofilter has some similarities with a constructed wetland, but is usually without plants.
• Stable environmental conditions and regular maintenance are required to ensure the biofilter is operating efficiently.
• One of the main challenges to optimum biofilter operation is maintaining proper moisture throughout the system.
• For large volumes of air, a biofilter may be the only cost-effective solution.
• Fish require oxygen to metabolize food and grow, as do bacteria communities in the biofilter.
• The first step of nitrification in the biofilter consumes alkalinity and lowers the pH of the system.
• A septic tank and aerobic and biofilter units exist which represent scaled down versions of municipal sewage treatments.
• A biofilter provides a substrate for the bacterial community, which results in thick biofilm growing within the filter.
• Typically, a biofilter has two or three phases, depending on the feeding strategy ( percolating or submerged biofilter ):
• Typically, a biofilter has two or three phases, depending on the feeding strategy ( percolating or submerged biofilter ):
• Originally, biofilter was developed using rock or slag as filter media, but different types of material are used today.
• Vermifilters are a type of wastewater treatment biofilter or trickling filter but with the addition of earthworms to improve treatment efficiency.
• In 2001, Plum Creek at their Medium Density Fiberboard facility completed the installation of a biofilter, a new air emission treatment technology.
• Aeration occurs passively by the natural flow of air through the process ( three phase biofilter ) or by forced air supplied by blowers.
• In this context, a biofilter located after a septic tank constitutes a robust process able to sustain the variability observed without compromising the treatment performance.
• Barclay's arm is found to be out-of-phase, and further examination reveals microbes that were not detected by the biofilter.
• Nitrate is less toxic than ammonia ( > 100 mg / L ), and can be removed by a denitrifying biofilter or by water replacement.
• The bioswale, or other type of biofilter, wraps around the parking lot and treats the runoff before releasing it to the watershed or storm sewer.
• Although widely employed, the scientific community is still unsure of the physical phenomena underpinning biofilter operation, and information about the microorganisms involved continues to be developed.
• A number of companies offer these types or proprietary packing materials and multi-year guarantees, not usually provided with a conventional compost or wood chip bed biofilter.
