Показано, что обработка сточной воды этими импульсами увеличивает максимальную растворимость кислорода в воде приблизительно на 30 %, с 5,1 до 6,8 мг/дм3, ускоряет все процессы очистки сточной воды на 10–20 % и тем самым создает резерв производительности очистных сооружений. Сделан вывод о том, что при работе воздуходувок, управляемых сенсорами на кислород, которые включаются при концентрации кислорода около 2 мг/дм3 и выключаются при 4 мг/дм3, обработка воды в аэротенке ИЭМП приводит к уменьшению времени работы воздуходувок и соответственно экономии электроэнергии на 15–28 %.</p></abstract><trans-abstract xml:lang="en"><p>The influence of a pulsed electromagnetic field (PEMF) with a pulse repetition rate of 16 Hz and a magnetic induction of no more than 500 nT on the solubility of oxygen in water and on wastewater treatment in two operating treatment plants was studied. It has been shown that treating wastewater with these pulses increases the maximum solubility of oxygen in water approximately by 30%, from 5.1 mg/dm3 to 6.8 mg/dm3 and accelerates all wastewater treatment processes by 10–20% and thereby creates a productivity reserve of the wastewater treatment plants. It was concluded that when operating blowers controlled by oxygen sensors, which turn on at an oxygen concentration of about 2 mg/dm3 and turn off at 4 mg/dm3, water PEMF treatment in the aeration tank leads to a reduction in the operating time of the blowers and, accordingly, energy savings by 15–28 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>очистка сточных вод</kwd><kwd>активный ил</kwd><kwd>импульсное электромагнитное поле</kwd><kwd>концентрация растворённого кислорода в воде</kwd></kwd-group><kwd-group xml:lang="en"><kwd>activated sludge</kwd><kwd>impuls electromagnetic field</kwd><kwd>wastewater treatment</kwd><kwd>concentration of dissolved oxygen in water</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Beretta G.,.Mastorgio A.F.,.Pedrali L., Saponaro S., Sezenna E.
