To determine the effects of fish farm effluent on the reef-building species Pocillopora damicornis, we exposed different life stages of the coral to a gradient of effluent concentrations. After 81 d no juvenile coral survived at the Fish Farm site or at the site receiving intermediate concentrations, and survival rates were low (<20%) at the site receiving minimal effluent concentrations and at...

The role of sawdust in the removal of pollutants from textile wastewater has been investigated. The textile wastewater was treated by using sawdust as adsorbent and then filtered. The various physicochemical characteristics of sawdust treated and untreated textile effluent were analyzed. The maximum percent removal of 37% was observed for total suspended solids while minimum removal of 9% for c...

OBJECTIVES The primary objective of this pilot study was to investigate whether the therapeutic drug monitoring of imipenem could be performed with spent effluent instead of blood sampling collected from critically ill patients under continuous renal replacement therapy. METHODS A prospective open-label study was conducted in a real clinical setting. Both blood and effluent samples were colle...

Increased environmental awareness has promoted the need for improved feedlot runoff control. The use of vegetative treatment systems (VTSs) to control and treat feedlot runoff may enhance environmental security and protect water quality. Knowledge of effluent nutrient concentrations throughout the vegetative treatment system is required to evaluate impact on water quality and system performance...

Dyes are known to be harmful organic compounds for the environment since only a small amount of dyes can hazardous. So, treatment industrial dye effluent using commercial and effective catalyst is study's main objective. The adsorptive photocatalytic activity Egyptian bentonite was improved by acid treatment, followed incorporation cerium dioxide on surface via simple precipitation method then ...

Pharmaceutical contamination of shallow groundwater is a substantial concern in effluent-dominated streams, due to high aqueous mobility, designed bioactivity, and effluent-driven hydraulic gradients. In October and December 2012, effluent contributed approximately 99% and 71%, respectively, to downstream flow in Fourmile Creek, Iowa, USA. Strong hydrologic connectivity was observed between sur...

Distilleries produce vast amounts of contaminated effluents which if disposed to the water bodies will pose environmental problems hence need to treat this effluent. A membrane bioreactor with Pseudomonas fluorescens as a decolorizing micro-organism was employed for treatment of distillery effluent over 10 days. The effluent pH changed from being acidic (4.2-5.0) to neutral (7.3-8.0). The efflu...

The effluent generated from a thermal power plant waste is a mixture of several chemicals and to identify the effect of these chemicals on soil, a case study on naturally contaminated sites at Al-Musayyib region, Hilla city in Iraq has been carried out. Soil and water samples were collected from the sites and analyzed to identify the pollutants and their effect on soil characteristics. Laborato...

Coal-mine effluent treatment has the potential to both reduce environmental impact of and provide economic opportunities by recovering valuable minerals clean water. In this study, we modeled a novel process, which includes nanofiltration (NF), two-step crystallization, reverse osmosis (RO), electrodialysis (ED), multi-effect distillation (MED), NaCl crystallizer, performed techno-economic anal...

This study was carried out to investigate the effect of different waters; tap water (control), sewage effluent (100 % & 50 %), sewage effluent with Scenedesmus quadricauda and sewage effluent with Nostoc sp. on plant growth, leaf chlorophyll and Assessment of hygienic (fungi) of wheat and alfalfa plants. The obtained results showed that plant height, herb weight (fresh and dry), total chlorophy...
