Opis:: The paper presents the research results on the possibility of the integration of advanced oxidation process (AOP) involving Fenton reaction with nanofiltration (NF) for dairy effluent treatment. It has been found that Fenton oxidation reduces organic compounds, total phosphorus and total nitrogen. However, NF enables high ions retention derived from both effluent and Fenton oxidation components. As a result, it was possible to obtain water, which, without any harmful effects, could be discharged into environment. This water also fulfilled most of the requirements to be reused in dairy industrial plant.

Opis:: Chemical oxidation processes: Fenton process and catalytic ozonation with Mn2+ ions were investigated for effectiveness of formaldehyde (FA) oxidation. The influence of operational variables — O3, H2O2, Mn2+ and Fe2+ concentrations and reaction time were investigated. Researches were carried out on aqueous solution of FA, which concentration was 500 mg/l. Fenton process was investigated at pH 3 and catalytic ozonation at pH 7, 10 and 12. Results revealed that Fenton process was much more effective in FA degradation than catalytic ozonation with Mn2+ as a catalyst. The optimal H2O2/Fe2+ dosage for a Fenton process was 2000/1000 mg/l. COD and FA concentrations were reduced 59,6% and 79,5%. In case of catalytic ozonation with Mn2+ the eff ectiveness was much less and it was the biggest at pH 12 and Mn2+ dosage 25 mg/l where COD and FA concentration were reduced 14% and 38%. Therefore, Fenton process can be promising technology for FA wastewater pretreatment.
