Water transformations

The relative importance of the biofilm compared with the bulk water transformations of the wastewater is not just a question of flow conditions in terms of a daily variation. It is possible in the design phase of the sewer network to control the contribution of the biofilm by selecting a different — smaller — size pipe. [Pg.209]

Long.contmuod action of water transforms this compound into antimonious oxide —... [Pg.129]

An excess of water transforms antimonic chloride into orthantimouic acid or pyrantimonio acid, corresponding to pyrophosphoric acid.—... [Pg.130]

Triammino-thallic Bromide, [Tl(NIT3)3]Br3, is prepared in the same way. It becomes very quickly yellow in colour, due to partial decomposition. Water transforms it into the oxide, T1203, and on heating to 100° C. it loses ammonia and bromine, leaving a residue of thallous bromide. [Pg.60]

In the condition of Spleen-Yang deficiency, Gui Zhi can be used to stimulate water metabolism and accelerate water transforming into Qi, thereby relieving edema and difficult urination due to Yang deficiency. In addition, it can particularly warm the blood, stimulate the Heart and promote blood circulation, and can treat cold hands and feet, cramp of the muscles and pain due to cold in the blood. [Pg.182]

What happens to the entropy of a system as the components of the system are introduced to a larger number of possible arrangments, such as when liquid water transforms into water vapor ... [Pg.323]

Vigorous agitation is necessary for complete water transformation. With minor exceptions, the early results (as determined by Villard) showed that an increase in agitation caused a decrease in the number of water molecules in the hydrate. [Pg.327]

No detailed studies on catalyst degradation pathways in ionic liquids have yet been reported. Due to the reaction of [PF6] with water, transformation of P(OR)3 to P(OR)nF3.n has been observed/471 In the case of aqueous biphasic catalysis with TPPTS as ligand, it is known that migration of a phenyl ring and ultimately elimination of sulfonated phenyl derivatives can take place/59,601 However, when suitable (ionic) ligands are employed, the catalyst can remain active for more than 10 cycles and may be stable for more than 14 days under air/4 1... [Pg.83]

Equations (14-206) and (14-207) result from a balance of bubble buoyancy against interfacial tension. They include no inertia or viscosity effects. At low bubbling rates (carbon tetrachloride for vertically oriented orifices with 0.004 < D < 0.95 cm. If the orifice diameter becomes too large, the bubble diameter will be smaller than the orifice diameter, as predicted by Eq. (14-206), and instability results consequently, stable, stationary bubbles cannot be producecl. [Pg.1239]

Solid formulations for sustained drug release may contain mesogenic polymers as excipients. The mesogenic polymers form a matrix, which is usually compressed into tablets. Some of the most frequently used excipients for sustained release matrices include cellulose derivatives, which behave like lyotropic liquid crystals when they are gradually dissolved in aqueous media. Cellulose derivatives such as hydroxy-propyl cellulose or hydroxy-propylmethyl cellulose form gel-like lyotropic mesophases in contact with water, through which diffusion takes place relatively slowly. Increasing dilution of the mesophase with water transforms the mesophase to a highly viscous slime and then to a colloidal polymer solution. [Pg.1129]

The conversion of a-hydroxy acids into aldehydes with one less carbon has great importance in the chemistry of sugars. Oxidation with bromine water transforms aldoses into the corresponding aldonic acids, which, in the form of their calcium salts, are treated with aqueous hydrogen peroxide in the presence of ferrous or ferric sulfate (Fenton reagent) and are degraded to aldoses with one less carbon (Ruff degradation) (equation 479) [57]. [Pg.228]

An illustration of Lowry s concept of acid catalysis is given in Figure 7, where S is the molecule to be converted (rearranged) to T. The proton donators cited as examples are the oxonium ion an undissociated acid molecule HA, and water as a special case of HA, while the proton acceptors cited as examples are water (transformed to H30 ), and the acetate ion (transformed to acetic acid). Contrary to the concept of Arrhenius, Lowry s concept can explain why water as a proton donator and acetate ions as proton acceptors represent a power-... [Pg.11]

As a result we have obtained frozen C02-hydrate-saturated samples. The analysis of the thermo-baric changes in the pressure chamber during the process of hydrate and ice formation allows us to localized any phase transition in the soil samples as well as to calculate the water content, the volumetrical hydrate content (Hy) and the hydrate coefficient Kh (fraction of liquid water transformed into hydrate). [Pg.148]

Polder. A piece of previously submerged land, below the natural level of an adjacent body of water transformed to dryland and maintained by dikes. [Pg.655]
