Optimization of Circular Plate Separators with Cross Flow for Removal of Oil Droplets and Solid Particles
A circular gravity-phase separator using coalescing medium with cross flow was developed to remove oil and suspended solids from wastewaters. Coalescence medium in the form of inclined plates promotes rising of oil droplets through coalescence and settling of solid particles through coagulation....

| Summary: | A circular gravity-phase separator using coalescing
medium with cross flow was developed to remove oil and suspended
solids from wastewaters. Coalescence medium in the form of inclined
plates promotes rising of oil droplets through coalescence and settling of
solid particles through coagulation. It exhibits 22.67% higher removal of
total suspended solids (TSS) compared to separators without coalescing
medium. Moreover, it removed more than 70% of oil compared to
conventional American Petroleum Institute separators, which exhibit an
average of 33% oil removal. The flowrate required to attain an effluent oil
concentration of 10 mg/L (Qo10) at different influent oil concentrations
(Cio) can be represented by Qo10 3 1025 5 20.0012Cio + 0.352. The
flowrate required to attain an effluent TSS concentration of 50 mg/L
(Qss50) at different influent TSS concentrations (Ciss) can be represented
by Qss50 3 1025 5 1.0 3 106 Ciss
22.9576. The smallest removable solid
particle size was 4.87 mm. Water Environ. Res., 84, 299 (2012). |
