On-line Evaluation of Shape and Porosity Effects on Settling Behaviour of Flocs in Clarifiersplish 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 to predict the floc settling

European Standards for Drinking Water Treatment Chemicalsve’. This covers the purchasing procedures to be used by water suppliers, and is intended to promote free trade within the EU. 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

The Influence of pH When Precipitating Orthophosphate with Aluminum and Iron Salts 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.

Coagulation and Precipitation by an Alkaline Aluminium Coagulantaline coagulant was as efficient as alum regarding turbidity and humus removal but less efficient than PAX 18 in turbidity removal. 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

Colloid Charge Capacity — Its Measurement, Problems and Promiseolloidal phenomena, especially dosage control in charge-neutralization coagulation. Colloid charge titration (CCT) analysis can quantify this important extensive charge property — distinct from zeta potential (ζ), the intensive expression of interfacial charge. The analysis involves titration of a c

Dosing Control of Coagulants Based on On-line Monitoring of Suspended Solids in Sewage Treatment Plae concentration of suspended solids (SS) in the inlet. The SS was analyzed continuously with an on-line monitor..The dosage was based on the SS in three different ways. In one plant the dosage was flow- and SS-related; in another, dosage was independent of flow and SS; and in the third, dosage was o
