Disposal of tannery effluent will result in heavy metal contamination of land and will lead to many important health and environmental hazards. Aim of the work is to determine the effects of untreated tannery effluent and treated tannery effluent on seed germination and to biodegrade the effluent using fungi. Chemical methods of remove the heavy metals in tannery effluent will have metal bearin...

Coastal sandy soil is characterised by low fertility and poor physical properties. Distillery effluent, a liquid waste from the distillery industry contains large quantities of soluble organic matter and plant nutrients. It does not contain any toxic elements / compounds. In order to improve the physical properties and fertility of the coastal soil by utilising the distillery effluent, field ex...

In this study, the effect of soil structure under saturated and unsaturated flow conditions on nonreactive bromide (BR) transport was investigated. The soil structure treatments consisted of undisturbed columns (prismatic and granular structures), and disturbed columns (single- grain structure). A constant concentration (C0= 0.005 M) of bromide was supplied on the surface of the columns in a st...

In this work, the Upflow Anaerobic Sludge Blanket “UASB” reactor treated effluent wastewater to investigate process performance on a pilot plant scale. Municipal at high and medium strength with different organic load rate OLR (0.6-9) kg COD m-3day-1 flow of 20 l/h, up-flow velocity 0.4 m/h, hydraulic retention time HRT 9 h temperature (20-30 ºC) was evaluated. The concentration, including TSS,...

Several methods have been used to measure left ventricular regional blood flow in humans. However, limitations and lack of validation in patients are major problems. A continuous thermodilution technique to measure regional left ventricular blood flow in patients with coronary disease was validated in vivo. This technique permits simultaneous assessment of venous blood flow draining predominant...

This study was conducted to examine the possibility of using construction solid waste (CSW), an inevitable by-product of the construction and demolition process, as the main substrate in a laboratory scale multi-stage constructed wetland system (CWs) to improve phosphorus (P) removal from secondary sewage effluent. A tidal-flow operation strategy was employed to enhance the wetland aeration. Th...

Investigations were carried out to determine the composition of fungal flora in the studied sites. Samples of the raw effluent were collected along the flow channel and the retention pond. Water samples were also collected at the discharge point and up and down stream of the river from the discharge point. The samples were spinned at a speed of 250rpm for 10minutes and spread inoculated the dep...

[1] We report results on the effects of porewater pH and transients in porewater flow on the deposition and mobilization of colloid-sized clay particles within unsaturated sand columns. The deposition rates of illite under steady-flow conditions were essentially independent of pH, while the deposition rates of kaolinite nearly doubled as the pH decreased from 7.4 to 4.6. Mobilization of kaolini...
