The transport of fine-grained particles in estuarine and coastal waters is influenced by flocculation processes (aggregation and floc breakup). As a consequence, the particle size varies with time in the water column, and can be orders of magnitude larger than those of primary particles. In this study the variations in floc size is simulated using a size-resolved method, which approximates the ...
Oskar Weltmann (1930) showed that human blood serum diluted in distilled water in the proportion of 1 :50 does not become turbid at the temperature of boiling water. In the Weltmann reaction the degree of flocculation depends on the addition of electrolytes through heat. Thus, varying with the pathological process, the diluted serum needs different quantities of bivalent electrolytes for the ho...
A flocculant (DES0-0) was synthesized by epichlorohydrin and diethylamine, followed adding crosslinking agent such as ethylenediamine, diethylenetriamine triethylenetriamine to obtain the crosslinked polymer DES0-1, DES0-2, DES0-3. The flocculation effect of DES0-3 PAM studied measuring volume, transmittance particle size clarified solution after flocculation. results showed that triethylenetet...
This abstract presents a laboratory study of a coagulation/flocculation process on an urban snow melt mixture. Coagulation/flocculation is ubiquitous in water treatment, but has seen little use in the stormwater context. Using a jar-test procedure five different chemicals are evaluated as primary coagulants and their treatment performance on urban snow melt with respect to solids removal and me...
