Less corrosive than ferric chloride. Lower sludge production. Still in the development stage. Not so widely used. Liu and Chin (2009), Wei et al. (2009a), Zhan et al. (2010, 2011), Cao et al. (2011) PFS: Made by partially neutralized (prehydrolyzed) ferric sulfate. Enhanced amounts of highcharged, moderate MM hydrolysis species.
Ferric Sulfate is a toxic, nonflammable chemical compound with the molecular formula Fe 2 O 12 S 3. Its CAS is . The dark brown or yellow chemical agent is produced by the reaction of sulfuric acid and an oxidizing agent. Ferric sulfate is used in different fields such as dentistry and dermatology.
Ferric Sulfate Properties. The molecular formula for this chemical is Fe 2 (SO 4) 3 and its molecular weight is g/mol. It is slightly soluble in water, sparingly soluble in alcohol, and has negligible solubility in acetone and ethyl is insoluble in sulfuric acid and ammonia. Ferric sulfate is produced on a large scale through the reaction of sulfuric acid, an oxidizing agent ...
ALUM (aluminum sulfate) is a nontoxic material commonly used in water treatment plants to clarify drinking water. In lakes alum is used to control algae, not by killing the algal organisms, but by reducing the amount of the nutrient phosphorus in the water. Like most other plants, algae requires phosphorus to live an reproduce.
A process for the production of liquid ferric sulfate from finelydivided ferric oxide, sulfuric acid and water in a closed reaction vessel at temperatures . PROCESS FOR PRODUCING FERROUS SULFATE – M T Chemicals Inc. Generally speaking, this invention relates to a process for the production of ferrous sulfate from scrap iron.
Polyferric Sulfate production process is the most advanced technology of spray drying method. Poly Ferric Sulfate Solid Powder is easy to be damp when it is exposed in the air. Strong electric neutralization of colloidal substance in wastewater.
May 08, 2004· Ferric has wider effective pH range than alum, whose effectiveness decreases rapidly above pH 8. Important for precipitating metals at pH 9 or 10, maybe not relevant for TOC. Consider using ferrous sulfate (aka copperas). It is very cheap, (probably) more soluble than ferric, and you can aerate to ferric.
