dc.description.abstract | Bakalaura darba izstrādes gaitā ar dzelzs savienojumiem modificētas 5 dažādu purvu kūdras un 1 kūdras blakusprodukts, kā arī pētītas to izmantošanas iespējas notekūdeņu attīrīšanā no fosfātjoniem. Eksperimentos iegūtie rezultāti liecina, ka modificēta kūdra ir efektīvs sorbents, lai saistītu notekūdeņos esošos fosfātjonus. Darba gaitā secināts, ka modificētas Gāgu purva kūdras fosfātjonu sorbcijas efektivitāte notekūdeņos ir tik pat augsta, cik attīrīšanas iekārtās pašlaik izmantoto bioloģisko metožu efektivitāte.

dc.description.abstract | During the development of bachelor`s thesis, options of using modified peat for phosphate removal from waste water were studied. In the research there were used 5 types of different peat samples and 1 peat by-product that were modified with ferric chloride hexahydrate. The results that show that modified peat is effective sorbent and can attach phoshates from waste water with almost maximum efficiency. During the research it was concluded that the modified peat, that was gained from the bog Gāgu, can adsorb phosphates from the waste water as good as the methods that are used in the treatment plants at the moment.
