Sulfate digestion process for high purity TiO

T. A. LASHEEN

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 2,   Pages 155-160 doi: 10.1007/s11705-009-0005-z

Abstract: A titania slag product of Rosetta ilmenite assaying 72% TiO is treated by the sulfate process option of the pigmentary TiO manufacture. The relevant factors of acid concentration, particle size, slag/acid ratio besides the reaction temperature, and time have been studied. After dissolving the cured mass in dilute acid and clarification, the obtained solution was subjected to hydrolysis of its titanium content. The final product was bleached under reducing conditions to redissolve the residual coloring impurities before being dewatered and calcinated. The obtained results indicated that a leaching efficiency of about 92% was realized due to the presence of some refractory components in the working slag material, namely, rutile and magnesium iron titanate. The obtained white pigment assay attained up to 99.85% TiO , while the analyzed impurities involve 77 ppm Mn and only 14 and 7 ppm of total iron and V, respectively.

Influencing mechanism of high solid concentration on anaerobic mono-digestion of sewage sludge without

Yuyao ZHANG,Huan LI,Can LIU,Yingchao CHENG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 6,   Pages 1108-1116 doi: 10.1007/s11783-015-0806-x

Abstract: High-solids anaerobic digestion of sewage sludge was a promising process, but high solid concentrationinfluencing mechanism was systematically analyzed in this study through a series of static anaerobic digestionThe results showed that TS 6% was the boundary between low-solids and high-solids anaerobic digestionThe performance of anaerobic digestion was directly determined by the efficiency of mass transfer, andConsequently, the deterioration of high-solids anaerobic digestion was related to the blocked mass transfer

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 11, doi: 10.1007/s11783-022-1584-x

Abstract: To date, most efforts to control eutrophication have focused on reductions of external nutrient inputs, yet importance of nutrient stoichiometry and subsequent shift in plankton composition in aquatic ecosystemHowever, control measures are often targeted at and effective in removing a single nutrient from sewageand thus are less effective in removing the others, resulting in the changes of nutrient stoichiometrylong-term strategies for domestic wastewater management should not merely focus on the total reduction of nutrient
