This work is concerned with the efficiency of two different waste polymeric
materials as the filter media in a laboratory-scale bed coalescer in the
horizontal fluid flow mode, operating in a steady-state regime. The applied
materials are: waste polyethylene terephthalate from textile industry, BA1
and waste polypropylene from carpet industry, PP. Using these compressible
fiber polymeric materials, high bed porosity (up to 98%) could be obtained.
The investigation was carried out over a wide range of working conditions.
Bed permeability was varied in the range from 0.18•10-9 to 5.389•10-9 m2.
Operating fluid velocity was varied from 19 to 80 m/h, until the critical
velocity was reached. Different oily wastewaters were used in the
experiments. Oily wastewater is defined as the oil-inwater emulsion model
prepared using mineral oils of different physico-chemical characteristics:
crude oil (A) from Vojvodina region, two vacuum distillation fractions (A1,
A4), and blended petroleum product with a high paraffinic content (P1). Both
applied polymeric materials, BA1 and PP, showed high separation efficiency
for treatment of all investigated oily wastewater. However, the BA1 material
showed higher efficiency in a wider range of bed permeability and
physico-chemical characteristics of oil. [Projekat Ministarstva nauke
