Dispersed Air Flotation for the Removal of Solids from Water
Abstract: The quest for clean drinking water is fundamental to our existence as without it, there is no life. This research exploits the feasibility of using principles of the state-of-the-art flotation technique for solid-liquid water clarification. Dispersed air flotation [DAF] as a separation technique, involves dispersing (scattering) compressed air at high pressure into water. A fluidic oscillator is employed to generate minute micro-bubbles from a 20 microns pore sized ceramic diffusers …

Industrial wastewaters purification using the negatively charged with calculated dispersiveness of hydrogen bubbles and special electroflotator construction in the process of electroflotation
Abstract: The main problem in the all existing electroflotation methods of cleaning is the salinity of the space near cathode in the process of electroflotation that leads to formation of the salts sediments on the cathode that strongly cover cathode’s surface that may result of the total curtailment of the process of electroflotation. The other problem is that as anode is used the dense grid from the wire of the defined …

Optimizing the removal of Chromium from aqueous solution by adsorption using sugarcane bagasse
Abstract: In Ethiopian tannery and textile industries, chromium concentration before treatment ranges from 1000 ppm to 5000 ppm. From this concentration about 95 % of chromium exists in the form of Cr (III), which was toxic when its concentration exceeded 5 ppm and oxidized in to Cr (VI). This chromium was disposed to environment with effluent in the form of chromium III and chromium VI was highly toxic to humans, animals …

Spatial Distribution and Health Risk Assessment of Pesticide Residues in Groundwater of a Condensed Agricultural Area in Punjab (India)
Abstract: Modern agricultural practices involve an increased use of pesticides to meet the food demand of increasing population which results in contamination of the environment. An experimental protocol to monitor the presence of pesticide residues in groundwater of Sangrur, Punjab (India), an intense agricultural area, was undertaken as part of the study. Liquid–liquid extraction followed by gas chromatographic detection was used for the determination of pesticide residues. It was found that …

Steel corrosion about application of inhibitors
Abstract: In chronology of prevention of irreversible degradation of metals, inhibitors to corrosion have studied to inhibit use of toxic inhibitors. Prevention of toxic inhibitors has further studied to explore non-toxic inhibitors prepared from biological origins, e.g. plant originated or underwater organisms or expired drugs. Toxic organic inhibitors are further studied to select those in which toxicity is removed by dilution of processing chemical. If water pipelines are considered use of …
