Aluminium sulfate is a chemical compound with the formula Al 2 (SO 4) 3. It is soluble in water and is mainly used as a flocculating agent (causing contaminating particles to clump into larger, more easily trapped particles) in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. Aluminium sulfate is sometimes referred to as a type of alum
While an argument may be made that the metal salt under review is soluble according to standard methods (OECD 105), this is not supported by a Transformation/Dissolution study on aluminium sulphate at pH6 and 8 in which a significant amount of the substance salted out within 24 hours and in a 28 d study the substance was demonstrated to be extrememly poorly soluble following TDp guidelines (CLP
Aluminium sulfate, alternatively spelled either aluminum or sulphate. Other names: Cake alum, Filter alum, Papermaker''s alum, Alunogenite. Solubility in water (soft water) in relation of température (g / L): (g/L = g as Al 2 (SO 4) 3 per liter of solution) The insoluble portion is maximum % (w / w). The solutions are to be stored (preferably) above 0 ° C. Chemical
Aluminium sulphate has zero basicity whereas that of the polymerized aluminium salts varies from about 50% for Al 2 (OH) 3 Cl 3 ( 10% w/w Al 2 O 3) to about 85% for ACH (24% w/w Al 2 O 3). The H + ions produced by aluminium sulphate, PACl (10% w/w Al 2 O 3) and ACH are 6, 3 and 1, respectively. High basicity coagulants therefore depress the pH of the treated water less than aluminium
Aluminium sulphate solid slabs, kibbled and powder. Accepta 8301 is a primary coagulant that is ideal for use in industrial effluent treatment including wastewaters from food, dairy, oil, textiles and chemical industries. Aluminium sulphate works by neutralising the negative charge on suspended and colloidal matter to produce compact flocs
Par mg/L aluminium sulfate added there (30/594) = °F lower Alkalinity (TAC), and is formed (264/594) = mg of free CO2, and is also formed (156/594) = mg of aluminum hydroxide (as insoluble flocs), and (288/594) = mg of dissolved sulphate.
Aluminium sulfate is a chemical compound with the formula Al2(SO4)3. It is soluble in water and is mainly used as a coagulating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. The anhydrous form occurs naturally as a rare mineral millosevichite, found in volcanic environments and on burning coalmining waste dumps. Aluminium sulfate is rarely, if
· Aluminium sulfate is an odorless, white hygroscopic crystalline compound, moderately soluble in water and insoluble in organic solvents. It has an acidic taste. Aluminium sulfate is rarely encountered in the anhydrous form.
Aluminium sulphate is an inorganic salt used for slug and snail control that is approved for use in the EU. It is highly soluble in water, nonvolatile and can persist in the environment. It is not highly toxic to mammals but is moderately toxic to fish and aquatic invertebrates.

Anhydrous aluminum sulfate is a white crystalline solid. Aluminum sulfate is also obtained as an 18hydrate Al2(SO4) forms are soluble in water, noncombustible, and primary hazard is the threat to the environment.
Thus, data from aluminium nitrate, sulphate and chloride for example have been used in this dossier. There is a strong body of evidence from these studies that the anion of "soluble" aluminium salts plays a minor role in bioavailability and all toxicity can be based on aluminium concentration (which does not vary enormously all other environmental parameters [pH, hardness, DOC, temperature etc

Solubility of the sulphates. The sulphates become less soluble as you go down the Group. The simple trend is true provided you include hydrated beryllium sulphate in it, but not if the beryllium sulphate is anhydrous. The Nuffield Data Book quotes anyhydrous beryllium sulphate, BeSO 4, as insoluble (I haven''t been able to confirm this from any other source), whereas the hydrated form, BeSO 4
· Aluminium sulfate is an odorless, white hygroscopic crystalline compound, moderately soluble in water and insoluble in organic solvents. It has an acidic taste. Aluminium sulfate is rarely encountered in the anhydrous form. Aluminium sulfate forms a number of different hydrates, the most common ones being the hexadecydrate Al 2 (SO 4) 3 ·16H 2 O and octadecydrate Al 2 (SO 4) 3
