background: photoreactivation of microorganisms following uv disinfection is a disadvantage of using uv technology for wastewater treatment, since in some cases it may even reach several logarithms. the aim of this study was to evaluate the possibility of the photoreactivation of indicator bacteria (coliform and streptococci) in the irradiated effluent. methods: this study was performed using t...

The principal cause of primary non-function in orthotopic liver transplantation is thought to be preservation injury to the microvasculature. We, therefore, evaluated if effluent levels of hyaluronate, whose uptake is an endothelial cell marker, could predict early graft function and ultimate graft outcome in orthotopic liver transplantation. A total of 102 cases were studied in two phases. In ...

Improving swine effluent management practices requires understanding of the fate of nutrients derived from swine effluent in soil quality. This study was conducted to evaluate the effects of long-term swine lagoon effluent application on nutrient distribution in an alkaline Okolona silty clay, an acidic Vaiden silty clay, and a Brooksville silty clay loam. Swine effluent has been applied using ...

Acute toxicity tests were performed over a period of 120 hours using different concentrations of effluent of treated rubber wood processing wastewater on freshwater fish, Poecilia reticulata. The LC50 values of the effluent exposed to P. reticulata for 24, 48, 72, 96 and 120 hours were 19.77, 19.55, 19.25, 18.99 and 18.75 ml/dl respectively. Mortality was observed in a dose dependant manner. Th...

The filamentous green alga Cladophora grows to nuisance proportions in Lake Ontario. Stimulated by high phosphorus concentrations, growth results the degradation of beaches and clogging industrial water intakes with attendant loss beneficial uses. We develop a multi-module bioavailable model examine efficacy management strategies mitigating algal growth. platform includes modules simulating hyd...

To meet the increasing global water demand, local solutions, such as reuse of greywater, are becoming greater importance. While greywater reclamation has been implemented, full-scale adaptation limited by occurrence micropollutants in treated effluent. reduce risks posed micropollutants, advanced post-treatment is required. One promising technology implementation hollow fiber nanofiltration, wh...

The fertigation effect of distillery effluents concentrations such as 5%, 10%, 25%, 50%, 75% and 100% were studied on Trigonella foenu-graecu (Pusa early bunching) along with control (bore well water). On irrigation of soil with different effluents up to 90 days of harvesting, it was observed that there was a significant effect on moisture content (P < 0.001), EC, pH, Cl(-), total organic carbo...

Nitrogen removal performance and the ammonia-oxidising bacterial (AOB) community were assessed in the batch loaded 1.3 ha saturated surface vertical flow wetland at CSBP Ltd, a fertiliser and chemical manufacturer located in Kwinana, Western Australia. From September 2008 to October 2009 water quality was monitored and sediment samples collected for bacterial analyses. During the period of stud...

Pharmaceutical and personal care products (PPCPs) industries suffer inadequate effluent treatment due to the presence of recalcitrant substances, insufficient carbon source and nutrients. Biodegradation is the ability of microorganisms to metabolize pollutants in soil, sediment and water environment. There is great awareness in the positive impact that microorganisms play in protecting environm...

Estrogen activity was measured in wastewater effluent before and after polishing via soil-aquifer treatment (SAT) using both a (hER-beta) competitive binding assay and a transcriptional activation (yeast estrogen screen, YES) assay. From the competitive binding assay, the equivalent 17alpha-ethinylestradiol (EE2) concentration in secondary effluent was 4.7 nM but decreased to 0.22 nM following ...
