The flocculation test contained a rapid mixing (200 rpm 1 min), a slow mixing (50 rpm, 15 min), and a settling (10 min) and the size of the formed E1 floc
was measured using a laser diffraction instrument (Mastersizer 2000, Malvern, UK).
The results of experiments have indicated negative impact of used bioreactor construction on large flocs
The fractal dimensions were evaluated for flocs
formed under the influence of low (~ 5 ppmv) and high (~ 30 ppmv) concentrations of chemical type F (Figure 9).
Table 1 demonstrates that flocs
are a significant component of the MRD's SS transport regime: close to 100% (by volume) of the SS is transported as flocculated material.
At the same time, Phase II testing showed that a higher metal salt dosage was needed during the daytime "hot spot" period when floc
formation was poor.
The second FLOC
is Port Charlotte Town Center (5.0%), which is secured by fee and leasehold interests in a 489,695-sf regional mall located in Port Charlotte, FL.
Therefore, the particles must get closer to aggregate and thus, the flocs
formed are smaller and more compact.
The largest FLOC
, Vintage Park (4.8%), is secured by a 341,107-sf open-air anchored shopping center located in Houston, TX.
Fitch Loans of Concern: Fitch has designated two loans in the top 10 (6.3% of pool) as Fitch Loans of Concern (FLOC
) due to declining occupancy from tenants vacating and downsizing.
The largest FLOC
is the Hulen Mall (9.5%), which is secured by a 400,968-sf collateral portion of a 997,538-sf two-level regional mall located in Fort Worth, TX.
Fitch Loans of Concern: Fitch has designated four loans (11.1% of pool) as Fitch Loans of Concern (FLOCs
), including three of the top 15 loans (10.6%), one of which is in special servicing (1.7%).
Early addition provides more opportunity for breakage of chemically induced fiber flocs
, possibly leading to more uniform formation.
