... removal unit shows that it can be the most suitable option to solve that problem of the PSF. GSF uses the naturally occurring iron to remove arsenic by coprecipitation. In this process it produces arsenic rich iron sludge. Disposal of this sludge to the nature may pose a risk of secondary contamination...

... Scanning Calorimetry (HPDSC)RP, and sludge determinations were made at each time interval. Only a combined evaluation of the test results for the 10 000 h oil samples (a “Total Oxidation Products” approach) gave a reasonable estimation of the true oxidative state of the fluids. One shorter term test, ASTM...
