The Effects of Low-frequency Pulsed Electromagnetic Fields on the Cleaning of Household Wastewater
https://doi.org/10.18412/1816-0395-2023-8-27-31
Abstract
The effect of pulsed EMF with a pulse repetition frequency of 16 Hz on the decomposition of organic compounds in wastewater in the presence of activated sludge microorganisms has been studied. It is shown that aerobic purification of a mixture of wastewater and activated sludge in the presence of a continuous pulsed electromagnetic field with a frequency of 16 Hz and a magnetic induction of no more than 0.5 μT accelerates the process of ammonification by 25 %, nitrification and denitrification by 15 %, reduction of COD by approximately 20 %.The intensity of the increase in the biomass of activated sludge and the rate of its deposition were noted.
