Decolorizing the molasses effluent of yeast and alc. fermentation processes was studied using inorganic salts and com. (organic and inorg) polymers. The effluents were decolorized either untreated or after an anaerobic/aerobic treatment. The color elimination attained was 86% with the anaerobic/aerobic effluent when adding 60 mg/L of Al3+ as Al2(SO4)3·18 H2O at pH=5.0. Removal of color to the same extent was also obtained when the inorganic polymer (500 mg/L from Flocusol-PA/18.B) or the organic polymer (2500 mg/L Nalcofloc plus 3 mg/L N677-SC) were added to the effluent at its original pH value of 8.0-8.5. Under these conditions, a 55% COD removal was also achieved. For the raw effluent, color and COD removal were <3% and 2%, resp. for all the reagents tested.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Conference, WEFTEC ’99, Annual Conference & Exposition, 72nd, New Orleans, Oct. 9-13, 1999 called Application of high rate ballasted flocculation technology in wet weather flow treatment, Author is Stachowiak, Remy G., which mentions a compound: 17927-65-0, SMILESS is O=S(O)(O)=O.O=S(O)(O)=O.O=S(O)(O)=O.[H]O[H].[Al].[Al], Molecular Al2H8O13S3, Application of 17927-65-0.

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.

Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about A novel photoinitiated approach for preparing aluminum diethylphosphinate under atmospheric pressure. Author is Yang, Li; Han, Xin Yu; Tang, Xue Jiao; Han, Chang Xiu; Zhou, Yi Xiao; Zhang, Bao Gui.

A novel preparation of aluminum diethylphosphinate (AlPi) was carried out with free-radical addition reaction by means of UV-irradiation under atm. pressure. A solution of sodium hypophosphite was treated with ethylene and irradiated with UV light in the presence of an amount of photoinitiator effective to initiate the free-radical reaction between the hypophosphite anion and the double bond of the ethylene mol. The ethylene was micro-bubbled into the reaction mixture with the addition of the photoinitiator, and the gas-liquid contact surface and the photoinitiator concentration in the gas-liquid interface were increased largely. The yield of the final product could be improved to about 96%. The contents of P, Al in samples were detected by ICP, and the mol. structure of the samples was confirmed by 31P NMR, 1H NMR and FTIR spectroscopic anal. Thermal stability of the final products was investigated in detail by TG-DTA.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about The influence of environmental factor on the coagulation enhanced ultrafiltration of algae-laden water: Role of two anionic surfactants to the separation performance, the main research direction is environmental factor coagulation enhanced ultrafiltration algae laden water; algae laden water anionic surfactant separation; Algae-laden water; Anionic surfactant; Coagulation; Fouling mechanism; Ultrafiltration.Category: isothiazole.

With the acceleration of urbanization and the improvement of people′s living standards, more chems. that humans rely on are entering the city and surrounding water bodies. Anionic surfactants are one of the essential products for human beings. It is also one of the inducements that cause the eutrophication. The algae-laden water caused by eutrophication is a headache in the traditional water treatment process. To solve the problem, ultrafitration combined process was widely investigated to treat the algae-laden water. The presence of stimuli, low concentration anionic surfactant, probably interfere the performance of ultrafiltration process during algae-laden water treatment. In this study, the influence of two typical anionic surfactants, sodium dodecyl sulfate (SDS) and sodium dodecyl benzene sulfonate (LAS), on the performance of coagulation-enhanced ultrafiltration was investigated. The aluminum sulfate hydrate and iron sulfate hydrate were resp. employed as coagulant. Based on the residual turbidity and zeta potential, 4 mg/L Al and 8 mg/L Fe were determined as the optimal coagulant dosage. The floc morphol. confirmed that Al-algae flocs with lower fractal dimension (Df) were looser and more porous compared to Fe-algae flocs. More coagulant was depleted by LAS due to the better hydrophobicity of LAS. During the filtration process, LAS caused a larger flux reduction compared with SDS regardless of the coagulant that was used. More organic compounds penetrate into membrane pores and block the pores with the presence of LAS since algal cell aggregation was weakened. Finally, the rejection of organic compounds by the coagulation-enhanced ultrafiltration process was studied, and the co-existing surfactants can cause effluent deterioration. Therefore, the presence of surfactants has a neg. effect to the ultrafiltration treatment of algae-laden water.

Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about Assessment of fixed bed of aluminum infused diatomaceous earth as appropriate technology for groundwater defluoridation, the main research direction is fixed bed alumina diatomaceous earth groundwater defluoridation.Safety of Aluminum(III) sulfate xhydrate.

Excessive occurrence of F- in groundwater supplies is a major issue in many regions of the world. In order to produce a reactive filter (AD) for use as an appropriate groundwater defluoridation technol., the classical co-precipitation method was adopted to enrich diatomaceous earth with alumina. In a laboratory-scale water system, the breakthrough profile, fixed bed operation parameters and the mass transfer parameters of an AD column reactor were determined to obtain design parameters for real GW defluoridation applications. The defluoridation process variables studied (i.e., AD bed height and initial F- concentration) had a direct impact on column breakthrough and operating parameters. The mass transfer anal. revealed that external and internal diffusion were not the rate-limiting step of the defluoridation process in the column reactor. Considering the magnitude of the desorbed F- and the phys. integrity of the spent AD using selected regeneration solvents (HCl, HNO3, H2SO4, NaOH and CH3COOH) at 2 different concentrations (0.1 and 0.05M), CH3COOH was identified as the most suitable solvent to regenerate spent AD. The presence of a substantial amount of total inorganic C (68 mg/L), whose dominant species is HCO3-, resulted in a decrease in defluoridation efficiency using real groundwater. Based on the physicochem. characteristics of the AD reactor effluents, we proposed a non-specific mode of adsorption as one of the underlying defluoridation mechanism. This was in addition to the specific mode of adsorption that was revealed earlier as the underlying mechanism of F- removal using AD.
