Integration of advanced oxidation process with nanofiltration for dairy effluent treatment

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.
