“…In order to safeguard both human health and the environment, such highly polluted effluent must be thoroughly treated before being discharged or used in any other applications. The wastewater from livestock slaughterhouses can be treated using a variety of technologies, including biological [5], physical [6], and chemical methods [7]. Each kind of treatment does, however, have benefits and drawbacks.…”

Although electrochemical methods are one of the most efficient approaches for treating wastewater, the type of wastewater to be treated, the type of electrode material employed, and the polarity direction all significantly affect how well these systems work. The prospective application of the proposed materials for the purification of slaughterhouse effluent has not been sufficiently explored in earlier studies, despite the fact that the materials (copper and stainless-steel) are reasonably inexpensive and easily accessible, especially in low-income countries. It is also unfortunate that previous research has not taken into account the potential effect of polarity direction in stainless-steel and copper electrode materials used for the purification of slaughterhouse effluent. This study investigated the potential effect of polarity direction for the purification of slaughterhouse wastewater using stainless-steel and copper electrode materials. Two electrode polarities were used in the study; stainless-steel (anode) to copper (cathode) and copper (anode) to stainless-steel (cathode). The potential effect of the contact time on the pollutants’ removal was also taken into account. Generally, the copper-to-stainless-steel polarity showed a relatively high removal efficiency compared to the stainless-steel-to-copper electrode polarity. For instance, under 20 min of contact time, the removal efficiencies of copper (anode) to stainless-steel (cathode) were higher than that of stainless-steel (anode) to copper (cathode) in 11 out of 14 investigated water quality parameters. From 40 min contact time, the copper (anode) to stainless-steel (cathode) performed higher than that of stainless-steel (anode) to copper (cathode) in 8 out of 14 investigated water quality parameters. Moreover, from 60 min contact time, the copper (anode) to stainless-steel (cathode) performed higher than that of stainless-steel (anode) to copper (cathode) in 11 out of 14 investigated water quality parameters. Based on the findings, it is clear that, in order to obtain desired performance, contact time and polarity direction should be carefully considered when developing electrochemical wastewater treatment systems.

The article deals with improving the sewage systems of small remote settlements in the Arctic climate to prevent industrial pollution of the environment. Preliminary monitoring of the wastewater temperature and quality was carried out. From the laboratory results of the experimental modelling, such as the coagulation, sedimentation, filtration, oxidation, and wastewater chemical precipitation, we developed a substitute for the traditional biological stage of sewage treatment with physicochemical methods. A real sewage water sample, taken for this study from a septic tank in a remote northern village, can be considered as a distinctive feature of the experiment. The best results obtained according to the scheme with the chemical precipitation of nitrogen compounds are demonstrated. In this case, the chemical oxygen demand (COD) index was reduced by 96.6%, the ammonium ions concentration by 99.5%, and the suspended solids concentration by 99.9%. A technological scheme for low-productivity wastewater treatment plants (WWTPs) in northern settlements is proposed. A comparison of the proposed scheme and the traditional schemes in terms of efficiency and cost was carried out. Further study and implementation of recommended methods of sewage treatment at existing and newly designed stations is expected to improve the effective operation of these treatment plants in arctic conditions.
