Removal of organic contaminants from aluminum chloride solutions / By J. C. (Jack C.) White, Aluminum chloride. Publisher: [Avondale, please submit an Update/Correction/Removal .   The mechanism of natural organic matter (NOM) removal by AlCl3and polyaluminum chloride (PACl) was investigated through bench-scale tests. The fraction distributions of NOM and residual Al after coagulation in solution, colloid and sediment were analyzed as changes of coagulant dosage and by:   The ability of locally laboratory-synthesized polyaluminium chloride (PAC) with high Al13 content (PAC-Al13) to remove organic, inorganic matter and colour from potable water, agricultural and electroplating wastewaters was evaluated relative to commercial PAC (PACI). PAC-Al13 used in this study was prepared using batch titration of NaOH into AlCl36H2O solution under vigorous stirring as Cited by: 1.   This invention relates to a process for the purification of hydrous aluminum chloride. More particularly, the invention relates to a process for the substantially complete removal of organic contaminants and iron, copper and other undesirable trace metals .

ALUMINUM CHLORIDE, SOLUTION is an aqueous solution of an acidic salt. Reacts exothermically with bases. May cause ethylene (also other alkenes) to polymerize violently [J. Inst. Pet. ]. A method for removing chloride from an aqueous solution having an initial chloride ion (CI') weight concentration, comprising: adding a magnesium compound to the aqueous solution, magnesium ion weight concentration being less than about 20% of the initial chloride ion weight concentration; adding at least two compounds comprising calcium ions (Ca 2+), hydroxide ions (OH -) and alυminale. aluminum-based coagulants (aluminum sulfate, polyaluminum chloride (PACl) and aluminum chlorohydrate (ACH)) were used to treat a highly organic surface water supply (DOC ranging between 10 and 30 mg/L), known as the Cow Pen Slough, located within central Sarasota. At a dose of 3 mg Al L−1 the best effects of turbidity, colour and organic matter removal were obtained using PAX-XL, which is polyaluminium chloride of high alkalinity.

However, due to the presence of contaminants (iron(III) chloride), it acquires a yellowish colour. ⇒ Aluminium Chloride Formula: AlCl 3 Industrially, aluminium chloride is used in the production of aluminium metal, but it also has a wide number of uses in the chemical industry particularly as a . Salt Contamination Organic Chlorides HCl Nitrogen Compounds in the Feed – Good water removal and water wash capabilities help – Limit fouling and corrosion. • Eliminate organic chloride feed sources • Eliminate in-house sources of organic chlorides (slops).

Chemically, color-producing compounds are classified as humic and fulvic acids. Color can be removed by chlorination and coagulation with aluminum or iron salts or organic polyelectrolytes. Chlorine oxidizes color compounds, while the inorganic coagulants can physically remove many types of organic color by neutralization of surface charges.
