Treated effluents from flue-gas-desulfurisation (from coal combustion power plants) can contain ppm levels of selenium, most commonly as selenate, but as much as 1 g l–1 of sulfur in the form of sulfate (5). special attention is paid to the removal of selenium ions
Novel Approach for Removing Selenium from Phillips 66 Ponca City, OK Refinery Effluent AFPM, Oct 19, 2015 3 Fe(OH)3, while selenate is difficult to remove with
Apr 01, 2017 The removal of selenium from complex industrial wastewaters such as the FGD effluents by adsorption is a promising process provided efficient pre-treatment steps are deployed. Because of the structural similarity of various chemical species (e.g., sulfate and selenate), ion exchange resins could be easily exhausted, thus limiting their
Aug 24, 2021 To improve selenium removal, higher ratios, of 2, 3 and 5% respectively, were also evaluated only for the effluents M2 and M5, for the same contact time (8 hours). Thus, after 8 hours of stirring at 300 rpm and 20°C, the pH and redox potential of treated effluents were measured and the supernatant was filtered (0.45 μm) before quantification
Selenium (Se) removal from synthetic solutions and from real Flue Gas Desulfurization (FGD) wastewater generated by a coal-fired power plant was studied for the first time using a commercial iron oxide impregnated strong base anion exchange resin, Purolite ® FerrIX A33E. In synthetic solutions, the resin showed high affinity for selenate and selenite, while sulfate exhibited a strong
Describe successful case studies of Se removal applied to aqueous effluents at the commercial or pilot stage, as well as cases of scaling up to full scale for these industry sectors: Power generation Mining and agriculture Oil and gas • Treatment is only one of three approaches for selenium removal: Prevention Source
Jan 17, 2014 The results show that MBBR can be a viable solution for biological selenium removal as well as nitrate removal from FGD and mine effluents. By combining the MBBR with traditional chemical treatment, very low effluent selenium concentrations can be reached. With so much focus on the selenium regulations, having a biological solution offers
cost-effective treatment approach to phosphorus removal from municipal secondary effluents. (2) Synthesized nano-magnetite was used as an adsorbent to develop an innovative technology for selenium removal from aqueous solutions. Each case involved a series of batch adsorption experiments conducted to evaluate adsorption kinetics,
The removal of selenium from aqueous medium is complex and expensive, because of the high wastewater volumes generated, low discharge limits (even in μg/L) and the presence of Se(IV) and Se(VI) species (Santos et al. 2015).As regulatory limits are becoming stricter, selenium removal from wastewater has become more and more challenging.

Mica-Tron Products Corp. has an extensive selection of grinding equipment available. Our newest grinder is a DCM Tech IG280SD rotary surface grinder which features a 24” chuck, with a 12” diameter diamond grinding wheel. Our CNC 11-20 Blanchard Grinder, was custom built for Mica-Tron Products Corp., by Gallery of Machines, and features a
Raymond mill is the vertical grinding mill, which is popular in many countries and has very long history. HGM Ultrafine grinder mill is special for super thin grinding. You can choose suitable mica grinding mill depends on your mica size, hardness, capacity and your cost budget.
This paper presents results of the research of micronization grinding of dry mica in a planetary ball mill. Investigation was conducted in order to improve the quality and to obtain clearly defined properties and characteristics of mica powder. The micronization grinding of dry mica was performed in four time periods: 30, 60, 120, and 360 minutes.
The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. NETZSCH is expanding its product portfolio with an agitator bead mill for the dry grinding
The photos show SEM views of mica powder processed with Yamaguchi wet-grinding, commercial ball-mill wet-grinding and jet-mill dry-grinding. Particles of our product are flatter,smoother and thinner and this is the reason why our products are appreciated and differentiates the performance which creates excellent effect that other makers can
Machining MACOR ® Machinable Glass Ceramic. MACOR ® machinable glass-ceramic possesses a unique microstructure, composed of small, interlocked plate-like mica crystals dispersed within the parent glass matrix. These randomly oriented crystals are key to the machinability of MACOR ®.The MACOR ® machining process is unlike that found in metals and plastics where plastic deformation occurs
Jun 09, 2017 The mica was ground in the 10-inch-diameter, open-circuit plant at a feed rate of 50 pounds per hour; the mica feed slurry contained 20 percent solids, and minus 14- plus 28-mesh Ottawa sand was the grinding medium.
