The process of physical filtration is the mechanical and physical removal of solids or fluids from a fluid through forcing the flow of the filtered liquid through a medium. This process is most simply described by the use of a medium having perforations smaller than the size of the particles in which are being endeavored to be removed. Processes in which are usually considered physical filtration methods are , hydrodynamic separation and reverse osmosis methods. Gross pollutant traps are the most common forms of physical filters, with the being our physical filter system.
Biofiltration is the disintegration of materials through bacteria, fungi or other biological means. Essentially the process of biodegradation is in which material is consumed by microorganisms. This process can be implemented effectively in stormwater treatment, in conjunction with soil. Due to soils high absorbance, water is absorbed into the soil media in which these bacteria and microorganisms live, and the contaminants are slowed in the soil and are hence consumed by the organisms living in the soil. The water flows out of the soil with contaminants removed. These microorganisms in fact use this process to increase their population and remove the contaminants more efficiently. The matter which is able to be consumed by these microorganisms are generally organic materials such as hydrocarbons and nutrients. Our BIOPROTECTORis our biofiltration system, on of the most advanced on the market. It utilises both physical and biofiltration systems to ensure maximum contaminant removal.
