For tertiary biological nitrification the autotrophic bacteria are using oxygen which is distributed evenly in the filter bed by means of a fine bubble aeration grid. Filtrate ammonia levels of &lt; 2 mg\/l ammonia-N are achieved consistently, even at water temperatures as low as 5 \u00b0C.","thumbnail_url":"https:\/\/brightwork.nl\/wp-content\/uploads\/2021\/11\/csf-modular-design.jpg"}
