In order to investigate the effect of different types of reactors on the nitrosation granular sludge, a continuous stirred-tank reactor (CSTR) was studied, using mature nitrosation granular sludge cultivated in sequencing batch reactor (SBR) as seed sludge. Results indicated that the change of reactor type and influent mode could induce part of granules to(More)
OBJECTIVE To quantitatively evaluate the long-term changes in anterior segment morphology by using ultrasound biomicroscopy (UBM) after laser peripheral iridotomy (LPI) in eyes with primary angle closure (PAC). METHODS This was a clinical case series study. A total of 54 eyes with PAC of 31 consecutive patients were enrolled. Routine ophthalmic and UBM(More)
Using synthetic ammonia-rich wastewater as influent, rapid start-up of the nitrification reactor was attained in a laboratory-scale column-type sequencing batch reactor (SBR) inoculated with aerobic granular sludge, by gradually increasing the influent NH4(+) -N concentration (100-1000 mg x L(-1)) and decreasing the hydraulic retention time (8-4 h) under(More)
Alternating anoxic/oxic conditions have profound effects on both ammonium (AOB) and nitrite (NOB) oxidizing bacteria. In this study the influence of alternating anoxic/oxic condition on nitrifying granules was evaluated in a laboratory-scale column-type sequencing batch reactor (SBR). The anoxic phase was extended from 10 min to 120 min by increasing the(More)
