  In our research synthetically produced greywater samples were treated with oxidative and coagulating agents after pre-treatment them by filtration on various filters. We characterised the quality of greywater samples with several parameters. We investigated these parameters on the untreated, pre-treated, and treated samples as well. We evaluated the efficiency of the treatments by measuring the characteristic parameters. The greywater treatment is a very important and effective opportunity for the reasonable freshwater usage. This type of treated water can be suitable for toilet flushing or irrigation. There are a several methods known from the literatures to preparation the greywater samples to reuse. We compared two of these methods in this article.

  In our research we pretreated synthetically produced greywaters with filtration on various filters, then we treated the samples with oxidative agents. We characterised the quality of greywater samples with several parameters. We investigated these parameters on the untreated, pretreated, and oxidated samples as well. We evaluated the efficiency of the treatments by measuring the characteristic parameters. In addition, we investigated the changes on the filter media’ surface with a scanning electron microscope (SEM). It was shown, that the most effective treatment combination for the greywater’s preparation for reuse is the filtration on silica sand or activated charcoal and silica sand combined filter media, then oxidation with hydrogen peroxide (10 mmol/dm3).
