A biofilter is a functional material obtained through the controlled thermal decomposition of organic raw materials from agricultural crops, forestry waste, sewage sludge, algae biomass, reeds and other organic compounds of natural origin. Due to their intrinsic properties, biofilters are widely used as adsorbents for the removal of a wide range of pollutants such as organic pollutants and heavy metals. Currently, the accumulation of pollutants in industrial, municipal and agricultural wastewater has become a serious environmental problem.This study reviewed publications that focused on the removal of heavy metals and organic pollutants using biological filters.

Key words: wastewater, pollution, adsorption, biofilters, environmental pollution, water bodies, surface water.
