Abstract
The purpose of this research was to examine water treatment improvement by using natural powdered zeolite (clinoptilolite). experiments were carried out at a laboratory and in a pilot-scaled water treatment plant. The pilot-scaled plant was fed with groundwater containing a high level of organic compounds from the existing waterworks in ithuania's n eringa r egion. The content of organic substances in the groundwater - characterized by chemical oxygen demand ( co D), varied between 5.0 - 40.0 mg o 2 l -1 h, colour (Pt scale), turbidity, co D and permanganate index. The drinking water had an undesirable colour, taste and odour due to high concentrations of organic substances in the groundwater. A fluidized batch process and adsorption of natural powdered zeolite were used for reducing organic substances in the water with the effectiveness of total iron concentration reduction by 96%. experimental research results are included in the article.
