floc

Increased Credit Enhancement: The repayment of three loans since the last rating action has contributed $31.5 million of principal paydown and increased credit enhancement offsetting some of the concern regarding the FLOCs and increased loss expectations.

Positively charged cationic flocculants interacted with E1 and produced electrostatic attraction, leading to the formation of small E1 flocs and the increasing of E1 removal rate.

describe methods for measuring flocs, factors that control floc properties, and the behavior of flocs in water treatment processes.

Table 1 presents flocs counts in aerobic activated sludge during the first experiment.

While there appears to be some degree of variability, a relatively large fraction of these flocs were globular in appearance.

The extracellular polymer of biomass floc was determined by biochemical analysis.

Gerhard Furrer, a geochemist at the Institute of Terrestrial Ecology in Zurich, and colleagues report in the 27 September 2002 issue of Science that aluminum flocs originate mainly from condensations of the aluminum complex Al[O.sub.4][Al.sub.12][(OH).sub.24][([H.sub.2]O).sub.12.sup.7+], or [Al.sub.13].

Flocculation is the process whereby smaller particles (inorganic and organic), water-stable soil aggregates, or flocs aggregate to form larger particles (flocs) in a flowing medium.

These positively charged hydroxide complexes destabilize the negatively charged suspended colloidal particles, allowing the particles to precipitate, or grow larger, and form flocs. Polymer coagulants (polyelectrolytes) are long-chained organic molecules that can become highly charged when dissolved in water.

Four loans (15.1% of the pool) are designated as Fitch Loans of Concern (FLOCs), three of which are in the top 15, including two regional malls that have suffered performance deterioration.

By controlling the pH and calcium content, they were able to regulate the interactions among fat droplets, making them stick together and form flocs, or clumps.
