Detailed analysis of household generated greywater (GW) samples is an essential task for the design of treatment systems before reuse. In this paper modern analytical methods will be discussed, which were applied to determine the ionic and elemental concentration of different GW samples. Ion chromatography (IC) and Microwave plasma atomic emission spectrometry (MP-AES) methods were used to spoor the composition of GW samples. It was shown that from the IC results and from calculated parameters (Na ee% and SAR) the application of raw or treated GW flows for irrigation is controlled. According to the elemental concentration, GW samples from laundry/kitchen sink and dishwasher proved to be the most contaminated compared to drinking water, while the concentration of the measured elements did not elevate as significantly in GW samples from shower/bathtub.
