Stone coal was successfully used to synergistically treat stainless steel slag (SSS) recover both chromium (Cr) and vanadium (V). The alloy with a Cr grade of 70.84% V 2.36% can be obtained by keeping SSS stone at ratio 50 : 31 1600 °C for 120 min. corresponding recovery rates are as high 99.51% 81.25%, respectively. And the content 2 O 3 in reduced is only 0.49%. It thus provides new idea co-processing application two solid wastes: increasing economic potential solving environmental issues.

The present study investigated the utilization of blood clam shells as a potential substitute for conventional media, well influence acclimation time on efficacy an intermittent slow sand filter (ISSF) in treatment real domestic wastewater. ISSF was operated with 16 h and 8 off, focusing parameters turbidity, ammonia, phosphate. Two media combinations (only [CC] + [SC]) were under two different acclimatization periods (14 28 d). Results showed that SC medium exhibited significantly higher removal turbidity (p < 0.05) compared to CC (45.99 ± 26.84 % vs. 3.79 9.35 %), while slightly > ammonia (23.12 20.2 16.77 16.8 %) phosphate (18.03 11.96 vs 13.48 12 %). Comparing periods, d period overall performances than 14 d. Further optimizations need be conducted obtain effluent value below national permissible limit, since are still higher. SEM analysis confirmed formation biofilm both mediums after acclimatization; further schmutzdecke carried out enrich results.
