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...

Accumulation of phosphorus in soil is a major factor limiting the operational life of land application waste disposal systems. Moreover, for nutrient management purposes and evaluation of potential environmental problems it is necessary to understand the impact of manure application on soil phosphorus sorption characteristics. In this study laboratory experiments were conducted to investigate t...

Municipal wastewaters are major sources of pollution for the aquatic biota. The purpose of this study was to determine the levels of some pharmaceutical products and the immunotoxic potential of a municipal wastewater aeration lagoon for the treatment of the domestic wastewaters of a small town with wastewater inputs from a 400-bed hospital complex. Endemic mussels were collected, caged and pla...

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...

Passage of cell-free extracts of rabbit reticulocytes through heparin-Sepharose affinity columns results in the loss of the ability of the effluent to initiate protein synthesis. This is shown by the loss of response to added rabbit globin mRNA or to inhibitors of initiation of protein synthesis, such as heparin and aurin tricarboxylic acid, and by recovery of initiation activity by addition of...

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...

Septic tank effluent is inherently high in sodium ions relative to divalent cations (high sodium adsorption ratio). The disposal of septic tank effluent to the soil will cause the sodium ions to disperse the clay colloids, resulting in a physical blocking of the soil pores. Hydraulic conductivity will be reduced and the effluent will fail to dissipate into the soil profile. In designing the dis...

The utilization of treated agro-industrial effluents has been recommended as sound option for agriculture irrigations practices and sustainable land management programme. This paper presents the impact of utilizing treated effluent form a distillery industry on physico-chemical properties of soils in an agriculture plot. The effluent was applied in 50 and 100% strength and a control plot receiv...
