The biological wastewater treatment problem of the small villages located in the Arctic zone is considered. The purpose of this research is to study the alternative wastewater treatment method in Northern settlements. Standard research methods were used: gravimetric and photometric methods of liquid analysis to achieve this goal. This article presents the physical-chemical wastewater treatment method, consisted of coagulation proses, oxidation, sand and sorption filtration. As a result of the laboratory research, the effects of pollutants removal are 96.6% (COD), 82.4% (ammonium) and 97.1% (nitrates). These effects were achieved by the technological scheme that includes a coagulation, two-stage sequential oxidation with potassium permanganate and ozone, and intermediate filtration too. The brands of coagulant and flocculant were selected, as well as their optimal doses.
