Developing of Analytical Methods for Determination of Greywaters’ Detergent Content
42-47Views:175In our research we improved the technologies for the determinations of greywaters’ detergent content. We examined the quantity of anionic detergent (ANA) in synthetic greywater with Hyamine reagent using two-phased titrimetric method. We added to the synthetic greywater samples phenolphthalein indicator, acid mixed indicator and chloroform. After we shaked the mixture, and we got two separated phase. We titrated the mixture with cation active Hyamine reagent. The quantity of the chloroform and the quality of greywater samples (syntetic and real) were also changed in these experiment to determinate the actual ANA content. It was shown that the applied method is representative and reliable, too.

Comparison of greywater treatment processes with coagulating agent and oxidizer
99-106Views:98In 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.

Examination of macro- and micro elements in the artificial bathwater samples
61-69Views:119During our research, micro- and macro element content of synthetically produced bathwater was examined. Previous studies, which were conducted at the Department of Environmental Engineering at the Faculty of Engineering, University of Debrecen, proved that the quality of domestic greywater is greatly varied. This diversity can also be observed in the case of greywaters. The examination of bathwater samples covered the contentanalysis of Al, Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Sr, Zn, Ca, K, Mg, Na, Li elements with the application of MP-AES method. The analysis of greywater’s micro and macro content is essential part in the control of irrigation systems, flushing as well as car washing, because its heavy metal content can have a significant effect on the environment. In this study, we would like to present the concentration values of micro and macro elements of the examined greywater samples. Furthermore, we would like to make a comparison among our result, previously examined greywater samples and drinking water samples, too.
