In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Application of high rate ballasted flocculation technology in wet weather flow treatment, published in 1999, which mentions a compound: 17927-65-0, Name is Aluminum(III) sulfate xhydrate, Molecular Al2H8O13S3, Reference of Aluminum(III) sulfate xhydrate.
An innovative treatment technol. to address wet weather events is the ballasted flocculation process (e.g. Actiflo/Microsep from USFilter). The principal benefits of a ballasted flocculation treatment system for wet weather flows include vastly reduced space requirements, rapid start-up and response times, relative insensitivity to fluctuations in raw water quality, and removal rates greater than conventional systems. The key behind the ballasted flocculation process is the use of continuously recycled ballast or fine sand, which attaches to a flocculated particle through a polymer bridge. The addition of ballast provides 2 benefits: the high sp. gr. sand weights flocculated particles leading to much faster solids settling, and the increase in collision frequencies between sand and flocculated particles dramatically increases flocculation kinetics, resulting in very short mixing times. With rapid particulate settling and flocculation kinetics in ballasted flocculation systems, process design must focus on several fundamental parameters within the clarifier to maximize removal efficiencies and minimize plant footprint. This design approach was adopted in pilot testing of the USFilter ballasted flocculation process during wet weather flows at a variety of sites from 1997 through 1999. High quality, consistent effluent characteristics were achieved despite varying influent conditions. High quality effluent was produced within minutes of start-up, ideal for addressing transient wet weather or peaking events. Removal efficiencies through the ballasted flocculation process of over 85% for total suspended solids and over 60% for BOD were demonstrated. Even with a total hydraulic retention time of 6 min, sufficient residence time for mixing and flocculation was available, resulting in a very small footprint approach for wet weather treatment. With high levels of solids removal in a compact footprint, ballasted flocculation provides a cost competitive alternative to conventional clarification and biol. systems for treating wet weather flows.
There is still a lot of research devoted to this compound(SMILES：O=S(O)(O)=O.O=S(O)(O)=O.O=S(O)(O)=O.[H]O[H].[Al].[Al])Reference of Aluminum(III) sulfate xhydrate, and with the development of science, more effects of this compound(17927-65-0) can be discovered.
