In adults, normal phosphate concentration in serum or plasma is 2.5 to 4.5 mg/dL (0.81 to 1.45 mmol/L) . Hypophosphatemia is defined as serum phosphate concentrations lower than the low end of the normal range, whereas a concentration higher than the high end of the range indicates hyperphosphatemia.

Sludge age is the length of time a particle of activated sludge stays in the treatment plant measured in days. In a biological phosphorus removal plant, sludge age is the amount (lbs) ... phosphate from the mixed liquor which is the mechanism of biological phosphorus removal. In the anaerobic zone PAOs will rapidly take up BOD (as VFAs) and release

The mechanical activation of β-TCP led to materials that could be used to form a cement with setting and mechanical properties demanded in clinical use. The setting times with 2.5% Na 2 HPO 4 -solution as liquid phase are in the range between 5 and 16 min and might be adjustable by varying the sodium phosphate content of the liquid.

Our current knowledge regarding the activation mechanism of GA is related to the correlation between the presence of phosphate and the protein's quaternary structure, in which dimers associate into tetramers, thus establishing the catalysis-competent state of the enzyme (26, 27). This model led us to expect phosphate ions interacting in the ...

Mechanical activation technique represents a unique process in which the mineral surface reactivity can be increased in addition to having new products. Phosphate is a one of the plant nutrients that can be produced from phosphate rock. However, direct usage of the phosphate rock has several limitations.

A novel inorganic matrix for fiber composites prepared from phosphate based geopolymer (PBG) was synthesized at ambient temperature. The mechanical property of PBG paste and the carbon fiber reinforced PBG composite was determined. Test results showed that the compressive strength of PBG paste at the age of 28 days was found to be 33.67 MPa.

The removal efficiencies of phosphate and fluoride are significantly enhanced by the mechanically activated CaCO 3, of which, as shown in S1, all the diffraction peaks had become almost unobservable, indicating that the regular crystalline structure of raw CaCO 3 was transformed into a nearly amorphous state under the action of mechanical force. The …
