Note d'application: | Used to complete the removal of insufficiently reduced pollutants at the treatment secondary level of and/or nonbiodegradable compounds removal of, nutrients, toxic and/or specific pollutants, heavy metals, dissolved inorganic solids and suspended solids, and pathogenic microorganisms. Merely under very specific conditions in the domestic wastewater treatment, or when the treatment effluent is to be used in some forms of water reuse, the degree of tertiary efficiency is required. The tertiary level can be obtained by combining some of the processes described at the secondary level, when complementary reduction of organic matter, nutrients and micro-organisms is desired. However, the most common is that the units described in the secondary degree of biological treatment are complemented with other treatment technologies to achieve the tertiary level.
