Modifications to the profile of production in factories directly affect the changes in the amount and composition of the resulting wastewater. Therefore, there is a continued search for new and effective methods for to intensify the removal of pollutants and neutralization. Conducted so far, studies suggest that a positive factor for various unit processes of wastewater treatment is a constant magnetic field (CMF). The objective of the study was to determine the effect of a constant magnetic field (CMF) induction 0,6T the efficiency of removal of nutrients from wastewater dairy reactors SBR. Tests were performed under laboratory conditions, in two variants, different load of activated sludge a load impurities. During the research it proved that the use of CMF was conducive to the elimination of biogenic compounds, although the significance of this factor in the majority of variants was not significant. Regardless of the variant of the experiment was observed very high removal efficiency of nitrogen and phosphorus from waste water dairy tested.

An alternative to aerobic wastewater treatment systems are anaerobic reactors. When designing anaerobic reactors attention is paid to the appropriate filling, pumping systems, or mixing systems, enabling the re-duction of technological limitations, which contribute to the improvement of end effects such as, quantity and quality of the resulting biogas and the quality of treated wastewater. Described experiment related to researches on the evaluation of the efficiency of removing contamina-tions from synthetic dairy waste water using anaerobic reactor equipped with an innovative mixing sys-tem. The efficiency of removal of organic compounds made studies ranged from 96.25% to 99.03%. The concentration of total nitrogen in raw wastewater was at a level of 148.36 ± 0 mg N/dm3 to 593.42 ± 94,92 mg N/dm3, and treated wastewater from 21.66 ± 19.71 mg N/dm3 to 28.73 ± 0.4 mg N/dm3. The concentration of total phosphorus in raw wastewater was at a level of 110 ± 0 mg P/dm3 to 441.16 ± 19.83 mg P/dm3, and treated wastewater from 16.49 ± 16.13 mg P/dm3 to 354 ± 14.18 mg P/dm3. The methane content of the biogas produced was at a level of from 0.0413 dm3 per 1 g COD introduced to 0.4367 dm3 per 1 g COD introduced.

Objective The study aimed to evaluate the application of ERPs neuromarkers for the assessment and treatment of a patient with chronic crossed aphasia after severe TBI and a long-term coma. Case report. An ambidextrous female patient, aged 29, suffered from posttraumatic chronic crossed aphasia, severe TBI and a prolonged coma after a car accident. The patient took part in two differentiated rehabilitation programmes of neurotherapy included 20 sessions of relative beta training and 20 sessions of rTMS; both programmes were combined with behavioural training. The patient was tested 3 times: before the experiment, after completion of programme A, and after completion of programme B. Results In the 1st recording, the neuromarker of aphasia was found – an excess of the P2 wave over the left temporal area. There was a cognitive control deficit – an excess of omission errors and an increase of RT variability – all indexes of sporadic ADHD. In the 2nd recording, slight improvements in cognitive control, and language functions were found. In the 3rd recording, after the rTMS sessions most of her cognitive dysfunctions had been resolved, including language functions. It should be stressed that the activation (especially the increase in the ERP potential of the right side over the frontal lobe) was found. The neuromarker of aphasia did not change, only the location had slightly moved frontally. Conclusions The application of ERP neuromarkers assists in the diagnosis, treatment, and academic success of an ambidextrous patient with chronic posttraumatic aphasia and sporadic ADHD. ERPs can be used to assess the functional brain changes induced by neurotherapeutical programmes
