Using as examples water bodies in different geographical zones (Lake Ladoga, the River Sukhona, shallow-water ponds of the North Caucasus) the known methods of water quality evaluation by means of oligochaetes are considered. There is no unique universal method of pollution bioindication in this ...
For water purification treatment various technologies are in use. There are two main approaches to water pollutions removal. First approach relies on the use of cheap adsorbents [2], [3] and second one employs photocatalysts like titanium dioxide. In 2001, Asahi et al. [4] prepared nitrogen ...

Several treatment methods have been proposed and used for decontamination of wastewater including biological, sedimentation, adsorption, membrane, and filtration13,14,15,16,17. Adsorption as a highly efficient and costly separation/purification method has proved its ability for dye removal from aquatic...
