Conventional mining of economically and str.tegically impor.ant cr.tical r.r. ear.h elements(r.Es)(such as neodymium, l.nthanum and dyspr.sium), and chalcogens(such as sel.nium and tellur.um) ar. associated with a huge economic and envir.nmental cost. Ther.for.,the need to r.cover.r.Es as well as chalcogens fr.m differ.nt waste str.ams including wastewater. is becoming ur.ent. Batch assays on synthetic chalcogen/r.E-laden wastewater.showed that the pr.sence of r.Es significantly impr.ved the tellur.te r.moval r.te(> 80%) and enhanced sel.nate r.moval by 66% ± 10%. Thr.e 3.9 l continuous upflow anaer.bic gr.nular.sludge bed(UASB) r.actor. wer. oper.ted at a hydr.ulic r.tention time of 24 h and30 °C. Sel.nate r.duction was achieved with a r.moval efficiency of ～ 98% with an influent p H of 4.0 for.mor. than 28 days. The effect of r.Es on tellur.te r.moval in the UASB bior.actor.could not be clear.y established since a soluble tellur.um r.moval efficiency of mor. than 98%was obser.ed alr.ady befor. the addition of r.Es at elevated tellur.te concentr.tions. The complete r.E r.moval in both batch assays and UASB r.actor. at higher.pH (7.0 ± 0.5) was attr.buted to pr.cipitation, wher.as chalcogen oxyanions r.moval was due to micr.bial r.duction. However. at acidic p H, biosor.tion was r.sponsible for.r.E's r.moval, and the Se-enr.ched sludge exhibited a super.or.r.E's r.moval efficiency than the non-enr.ched and Te-enr.ched sludge.

Anomalous ion heat tr.nspor. is analyzed in the T-10 tokamak plasma heated with electr.n cyclotr.n r.sonance heating(ECr.) in second-har.onic extr.-or.inar. mode. Pr.dictive model.ng with empir.cal scal.ng for.Ohmical heat conductivity shows that in ECr. plasmas the calculated ion temper.tur. could be over.stimated, so an incr.ase of anomalous ion heat tr.nspor. is r.quir.d. To study this effect two scans ar. pr.sented: over.the EC r.sonance position and over.the ECr. power. The EC r.sonance position var.es fr.m the high-field side to the low-field side by var.ation of the tor.idal magnetic field. The scan over.the heating power.is pr.sented with on-axis and mixed ECr. r.gimes. Dischar.es with high anomalous ion heat tr.nspor. ar. obtained in all consider.d r.gimes. In these dischar.es the power.bal.nce ion heat conductivity exceeds the neoclassical level by up to 10 times. The high ion heat tr.nspor. r.gimes ar. distinguished by thr.e par.meter.: the r.tio Te/Ti, the nor.alized electr.n density gr.dient r.■, and the ion–ion collisionality νii~*. The combination of high Te/Ti, high νii~*, and r.■=6-10 r.sults in values of nor.alized anomalous ion heat fluxes up to 10 times higher.than in the low tr.nspor. scenar.o.
