Abstract. Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have received high concerns due to their extreme persistence, and very few technologies have been reported for their complete destruction. For sound PFCs wastes disposal, mechanochemical method was employed using a planetary ball mill.

High milling temperature causes this. On the other hand, if milling temperature is too low, insufficient rapidly soluble sulfate is available and this causes "flash set" - an irreversible stiffening of the mix. Obtaining the optimum amount of rapidly soluble sulfate requires milling with a mill exit temperature within a few degrees of 115 °C.

Milling. Scales are generally brittle. One of the earliest methods used to break off the thin brittle scale from pipes was explosives: a strand or two of detonation cord ("string shot") placed with an electronic detonation cap at the appropriate location in the wellbore, most effectively at the perforations. ...

Micronization is a high-energy process that induces changes in the crystallinity of materials. As a result, the crystalline structures on the particles' surface are being destroyed and amorphous areas are formed.

Classical methods for nickel recovery are precipitation, oxidation, and crystallization. Nickel and sulfate tend to build up in the copper refinery electrolyte and can be removed by crystallization as NiSO 4 ·6H 2 O crystals from the bleed stream. They are then separated from the mother liquor in a centrifuge, and dried and bagged for shipment.

For hard scales, such as barium sulfate, mechanical removal (scraping, sand blasting, chipping, jetting, controlled explosives) is the technique most often employed. Because scale is rarely deposited evenly on tubular goods, milling technology power requirements vary greatly.

Suspensions of griseofulvin (GF, model drug) along with various dispersants produced by wet-milling were coated onto Pharmatose® to prepare NCMPs in a fluidized bed process. Hydroxypropyl cellulose (HPC, polymer) alone and with sodium dodecyl sulfate (SDS, surfactant) was used as base-line stabilizer/dispersant during milling.

The variation of the degree of amorphization of aluminum sulfate as a function of milling time is depicted in Fig. 4. Assuming that the non-activated aluminum sulfate was crystalline prior to milling treatment, the calculated degree of amorphization of aluminum sulfate milled for 1 and 5 h were 26% and 53.2%, respectively.

One approach to improve drug solubility is using amorphous formulations, which can improve solubility by up to a 1000-fold. Herein, amorphous curcumin (CUR) and amorphous solid dispersions (SDs) consisting of CUR, hydroxypropyl cellulose (HPC) and/or sodium dodecyl sulfate (SDS) were developed using vibrational ball milling.

However, corn wet milling operations differ from other processes in that they are also sources of SO2 and VOC emissions, as described below. The corn wet milling process uses about 1.1 to 2.0 kg of SO2 per megagram (Mg) of corn (0.06 to 0.11 lb/bu). The SO2 is dissolved in process waters, but its pungent odor is present in the
