Ultrasonic Pre-treatment of Biological Sludge: Consequences on Disintegration, Anaerobic Biodegradability and Filterability
In spite of that, there is disagreement in the literature about the effect of MLSS on the filterability
of membrane bioreactors (LOUSADA-FERREIRA et al., 2010), including studies that demonstrate the existence of a direct relation between MLSS and the TMP (KATAYON et al., 2004; MENG et al., 2006) and other studies in which no major evidence of such parameters were found (ROSEMBERGER; KRAUME, 2002; LOBOS et al., 2008).
Its Univeral filters are used for filtering slurries with poor filterability
, and for cake washing, plus cake dewatering.
RJA Dispersions' new FX dispersions provide ultra stability and filterability
. Their 100-150 rim mean size, with D99 typically under 300 nm, provides the rheological consistency required for long-running maintenance-free operation.

The company's nonwovens composed of ultrafine fiber realize well filterability
and texture and are used in a wide range of application areas, including liquid filters, air filters, battery separators, capacitor separators, coalescers, medical products, HVAC, HEPA, cabin air filters, acoustics, water purifiers, coffee filters and household products.
A full suspension sample size (15 mL) is not tested due to the presence of cellulose which interferes with filterability
. Only one mL is tested in the 900 mL vessels.
