In this study, twelve Mallards living in an artificial wastewater wetland were exposed to treated wastewater containing 1 x 104 x 10 enterococci 100 ml for a period of 55 days. Faecal samples were collected before, during and after exposure and analysed for Enterococcus spp. The isolates were phenotyped using the PhenePlate system. 270 Enterococcus spp. of Mallard origin were analysed, together...

The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by governments and official entities worldwide. Irrigation with wastewater may have implications at two different levels: alter the physicochemical and microbiological properties of the soil and/or introduce and contribute to the accumulation of chemical and biological contaminants in s...

this document provides feasibility study of using treated domestic wastewater in concrete mixing. today, concrete is one of the most important construction materials. from first time that concert was used in construction materials, always the drinkable water used for concrete mixing water. domestic wastewater contains about 400 ppm of organic materials. after the treatment of wastewater, concen...

Whenever good quality water is scarce, treated municipal wastewater will be considered for using in agriculture. In this research, raw and treated wastewater from Serkan Wastewater Treatment Plant, Hamadan province, Iran, were used to determine the transfer coefficient of Fe, Ni and Mn from soil to plant and some soil properties in potato cultivation under lysimetric conditions. Irrigation trea...

Hookworm infection contributes around 700 million infections worldwide especially in developing nations due to increased use of wastewater for crop production. The effective recovery of hookworm ova from wastewater matrices is difficult due to their low concentrations and heterogeneous distribution. In this study, we compared the recovery rates of (i) four rapid hookworm ova concentration metho...

Global water shortage is placing an unprecedented pressure on water supplies. Treated wastewater is a valuable water resource, but its reuse for agricultural irrigation faces a roadblock: the public concern over the potential accumulation of contaminants of emerging concern (CECs) into human diet. In the present study, we measured the levels of 19 commonly occurring pharmaceutical and personal ...

Toxic chemical nature of tannery wastewater makes it difficult to be treated by routine biological treatment processes. Microbes, already present in tannery wastewater can adapt to these conditions and degrade the organics in tannery wastewater. In the present contribution, three bacterial electrogenic strains, tolerant to tannery environment, were isolated from soil contaminated with tannery w...

Dissolved organic nitrogen (DON) derived from wastewater effluent can participate in reactions that lead to formation of nitrogenous chlorination by-products, membrane fouling, eutrophication, and nitrification issues, so management of DON is important for both wastewater reuse applications and nutrient-sensitive watersheds that receive discharges from treated wastewater. This study documents D...

The risk of human hookworm infections from land application of wastewater matrices could be high in regions with high hookworm prevalence. A rapid, sensitive and specific hookworm detection method from wastewater matrices is required in order to assess human health risks. Currently available methods used to identify hookworm ova to the species level are time consuming and lack accuracy. In this...
