Die Inversion am Kreis bzw. an der Kugel,on of rice starch granules was coagulated with alum and the optimal pH identified at 5, 20 and 40°C. Experiments on floc development were carried out at the optimised pH values and under conditions in which the turbulence scaling parameter, ., the rate of energy dissipation per unit mass was held co

Die Inversion am Kreis bzw. an der Kugel,plish this, both experimental and computer image analysis methods were adopted. If the settling velocity of the flocs is measured, the density/porosity distribution of the flocs can be easily derived by using a modified Stokes formula. Computer software was developed [4] to predict the floc settling

Development of European Standards by the European Committee for Standardization (CEN) committee TC 164/WG 9 began during 1989. Standards are in various stages of preparation

Wie bildet man ein Projektteam?, when adding solutions of ortho-P to fresh hydroxides produced from the different salts is described. In most cases more ortho-P was precipitated by adding metal salts to ortho-P than by adding ortho-P to the hydroxides of the metal salts..Ferrous sulphate precipitated ortho-P in a narrow pH range.

With respect to P-precipitation, alum performed best while higher dosages of ALTON were needed to obtain the same P-removal. PAX 18 was least efficient here. A simplifi
