Arsenic Removal and Recovery from Copper Smelting …
Removal and recovery of high levels of arsenic (As) in copper smelting wastewater present a great environmental challenge. A novel approach was investigated for the first time using TiO2 for As adsorptive removal from wastewater and subsequent spent adsorbent regeneration and As recovery using NaOH. EXAFS results demonstrate that As(III), as the only As species present in the raw water, …

Pickling is the removal of any high temperature scale and any adjacent low chromium layer of metal from the surface of stainless steel by chemical means. Where the steel has been heated by welding, heat treatments or other means, to the point where a coloured oxide layer can be seen, there is a chromium depleted layer on the surface of the steel underneath the oxide layer.
The defects and subsurface damages induced by crystal growth and micro/nano-machining have a significant impact on the functional performance of machined products. Raman spectroscopy is an efficient, powerful, and non-destructive testing method to characterize these defects and subsurface damages. This paper aims to review the fundamentals and appliions of Raman spectroscopy on …
WHEY PROCESSING | Dairy Processing Handbook
The processing cost of electrodialysis depends very much on the de-mineralization rate. Increasing the capacity in steps from 50 % to 75 % to 90 % doubles the processing cost per step. This means that it is four times as expensive per kilo of product solids to demineralize to 90 % than to 50 %; the reason is that plant capacity is reduced at 90 % demineralization.
Salt Damage and Rising Damp Treatment in Building …
Salt damage can affect the service life of numerous building structures, both historical and contemporary, in a significant way. In this review, various damage mechanisms to porous building materials induced by salt action are analyzed. The importance of pretreatment investigations is discussed as well; in coination with the knowledge of salt and moisture transport mechanisms they can give

Silicon Wafer Manufacturing Process - SOI Wafers | …
The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage-free. On the other hand, the final polish does not remove any material. During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.
Most flat-rolled coil processing operations use some sort of roller leveling technology. Operations people understand what these machines can do to improve the quality of the product they produce. In the competitive marketplace, customers demand and get more that just flat sheets or slit coils.

Acid gas treatment and removal technologies separate sour gases—highly corrosive CO 2 and often deadly H 2 S acid gases—from saleable natural gas streams in a process known as gas sweetening. Once removed, the CO 2 and H 2 S are usually vented in low concentrations, flared, and then reinjected or otherwise properly disposed of.
