this work investigates the use of fenton’s process (ph 5.5 and 6; 0.10-0.50 mm fe(ii); molarratios fe(ii) to h2o2 of 1:5-1:20) combined with flocculation for the treatment of groundwater which is richin natural organic matter (nom) (10.6±0.37 mg c/l) and arsenic (110±6.7 μg/l). changes to the character ofthe residual nom fractions were followed, as well as the removal efficiencies of nom and ar...

Purpose of this clinical research study was, to determine the efficacy of plain water mixed with pure natural honey, to be used in the inflammation of the kidney (Nephritis) patients. 10 patients aged 18 to 21 years, (4 females, 6 males) with non- sever nephritis were given[three times a day] one standard glass of plain boiled water mixed with 4-table spoons of pure natural honey (Mel) for 14 d...

this paper presents a mapping procedure for risk mapping of water and wind erosion, whichhelps to identify protective measures needed in the planning and management of natural parks. the map of water erosion risk was developed by combining the original and revised universal soil loss equation methodologies (usle-rusle), and the map of wind erosion risk was developed using quirantes’ method. usi...

natural gas is often associated with nitrogen and heavy compounds. the heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. therefore, heavy components separation can be a necessity and produce useful products. virtually, all natural gases are containing nitrogen ​​that would lower the heating value of natural ...

A rapid coliphage analysis technique for enumerating coliphages in natural waters has been evaluated by water quality laboratories located throughout the United States. Correlations were established between coliphages and coliforms in natural water systems. These correlations were highly significant. This relationship can thus be used to determine the number of fecal or total coliforms present ...
