Biofilttijärjestelmiä
Biofilttijärjestelmiä, or biofilter systems, are wastewater treatment technologies that utilize a biological process to remove pollutants. These systems typically consist of a porous medium, such as gravel, sand, or plastic, which is inoculated with microorganisms. As wastewater flows through the medium, the microorganisms break down organic matter, nutrients, and other contaminants. The effectiveness of a biofilter system depends on several factors, including the type of medium, the flow rate of the wastewater, the temperature, and the specific microbial community present.
There are several types of biofilter systems, including intermittent sand filters, trickling filters, and constructed wetlands.
