Silica removal is a specific case of anion exchange and is typically accomplished with a strong base resin in the hydroxide form. Since silica acts as a very weak acid, the ex- change reaction for silica removal is as follows: H3SiO4 s + OH-R ~" H3SiO4 g + OH-s (1) HaSiO4 s + C1-R '~ H3SiOj R + Cl-s (2) M. Ben Sik Ali et al. / …

As emerging organic contaminants, siloxanes have severe impacts on the environment and human health. Simple linear siloxanes and derivates, trimethylsilanol (TMS), dimethylsilanediol (DMSD), monomethylsilanel (MMST), and dimethylsulfone (DMSO2), are four persistent and common problematic compounds (PCs) Editor's Choice: Machine …
Respirable crystalline silica dust. Silica is a natural substance found in concrete, bricks, rocks, stone (including artificial or engineered stone found in composite kitchen benchtops), sand and clay. RCS dust is created when materials containing silica are cut, ground, drilled, sanded, polished or otherwise disturbed.

This involves adsorbing silica over an Aℓ or Mg hydroxide floc. This co-precipitation can be carried out under hot or cold conditions. It is often carried out at the same time as CaCO 3 precipitation for carbonate removal.. silica removal using Mg 2+. When magnesium is present in well water and when its pH level is adequate, it will precipitate with some of …
"Shape" was the first criterion claimed to explain the specificity between organic structure-directing agents (OSDAs) and zeolite micropores. With the advent of computational chemistry methods applied to study the effectiveness of SDA–zeolite combinations, "energy" (mainly van der Waals) became the most commonly invoked …
Produced water from steam-assisted gravity drainage (SAGD) operations is a complex mixture of inorganic and organic constituents. Silica, carbonate and bicarbonate, and hardness are three inorganic constituents of interest, whereas the organic contaminants are composed of free and emulsified oil (F&EO) and water-soluble organic (WSO) …
