Investigation of protozoa as indicators of wastewater treatment efficiency in constructed wetlands

Population analyses of microfauna at a Water treatment Plant at Shebeen Alkoom, Minufeya, Egypt.

“…Monthly results showed a significant correlation between total protozoa and: manganese, Calcium, Ammonia plus dissolved oxygen. On the other hand, a negative significant correlation was found to occur between population density of protozoa and both rotifers, and total coliform bacteria, which agreed with Sibille et al (1998); Stevik (1998); Bomo et al (2004); Chabauda et al (2006);and Papadimitriou et al (2010).…”

Evaluation of an alternative method for wastewater treatment containing pesticides using solar photocatalytic oxidation and constructed wetlands

“…They are designed to take advantage of many of the processes that occur in natural wetlands, but do so within a more controlled environment (Vymazal and Bfezinova, 2015). They have the ability to efficiently treat a variety of wastewaters, removing organics, suspended solids, pathogens, nutrients and heavy metals, while their construction and maintenance cost is relatively low, since they are practically self-sufficient (Antoniadis et al, 2007;Papadimitriou et al, 2010).…”

Microfaunal indicators, Ciliophora phylogeny and protozoan population shifts in an intermittently aerated and fed bioreactor

“…Protozoan predation of both dispersed bacteria and peripheral cells of the flocs improves sludge sedimentation and effluent quality by reducing effluent turbidity, Biological Oxygen Demand (BOD) and suspended solids (SS), and decreases the risk of potential bacterial pathogens [1,2]. In particular, ciliates are proposed to be representative indicators of the operation of the wastewater treatment plants (WWTP) because of their rapid response to changes in wastewater composition and plant operating conditions [1,3].…”
