Tubificidae is often used in the wastewater treatment systems to minimize the sludge production because it can be fed on the activated sludge. The process conditions have effect on the growth, reproduction, and sludge reduction efficiency of Tubificidae. The effects of the water quality, density of worms, pH, temperature and dissolved oxygen (DO) concentration on the respiration rate of Tubific...

In order to examine the effects of some physicochemical parameters on zoobenthic community structure in Porsuk Stream, seasonal samples were collected from 6 stations between 2020-2021, and also measured. Within scope study, a total 30 families, 4 Gastropoda, 1 Bivalvia, 3 Clitellata, 22 Insecta, identified. Families Tubificidae, Erpobdellidae, Chironomidae identified at each station. Dominant ...

Due to high waste sludge disposal at wastewater treatment plants and increasing phosphorus scarcity, there is a need combine removal nutrient recovery. One way achieve this by incorporating ecological processes into treatment. Positive species interactions, such as facilitation, are critical increase productivity of biomass In study we showed the potential using principles including interspecif...

Genotoxicity of 5-fluorouracil (5-FU), etoposide (ET) and cadmium chloride (CdCl2) was evaluated in Limnodrilus udekemianus, cosmopolitan tubificid species, by alkaline single-cell gel electrophoresis (comet assay). Groups of 50 individuals were exposed in vivo in water-only short-term (96 h) tests to 5-FU (0.004, 0.04, 0.4, 4 and 40 μM), ET (0.004. 0.04, 0.4 and 4 μM) and CdCl2 (0.004, 0.04, 0...
