A pump-mix mixer-settler was demonstrated to have an over-all efficiency greater than 90% for the extraction of UO/sub 2/(NO/sub 3/)/sub 2/ from TBP at total flow rates up to 45 gpm. Phase separation was satisfactory at 45 gpm, at which flow rate the residence time in the settlers was 11/2 min.

Wastewater Plate Settler - Mega-SETTLER - JMS

JMS Mega-SETTLER (Wastewater Plate Settler System) was installed in the last zone of this existing basin where after significant solids have settled, the Plate Settlers polish the remaining solids. The addition of Plate Settlers was key to solids removal within the existing footprint and avoided the addition of an additional basin.

Separation efficiency of the cell settler was above 98%. Based on the growth and glucose consumption rates, fresh media was added to the culture and the turnover rate for the bioreactor was set at a maximum of 1.5 times the bioreactor volume per day.

Gravity filtration - Wikipedia

Gravity filtration is a method of filtering impurities from solutions by using gravity to pull liquid through a filter. The two main kinds of filtration used in laboratories are gravity and vacuum/suction. Gravity filtration is often used in chemical laboratories to filter precipitates from precipitation reactions as well as drying agents, inadmissible side items, or remaining reactants.

Gravity Separation - an overview | ScienceDirect Topics

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Extraction Equipment - Mixer Settler - Separation Processes

The droplets are then allowed to settle by gravity in the main part of the vessel. Most settlers consist of a horizontal vessel, because the separating efficiency is proportional to the area of the phase interface. To increase the size of the droplets and hence their settling rate, the dispersion may be passed through a coalescer (packing or ...
