“…Matsumoto et al (1993) developed a method to determine biodegradable organics in oily wastewater using a culture solution containing nutrients and acclimated microorganisms. Sutton et al ( 1993) reported pilot-study results (involving three General Motors plants) for treating oily wastewater (metal-working-fluid wastewater) with a system that consisted of an aerobic, suspendedgrowth reactor coupled to a membrane ultrafiltration unit. Tonelli and Canning ( 1993) also treated oily wastewater using a similar system which consisted of an aerobic reactor with solids retention time of greater than 30 days followed by an ultrafilter as a clarifier.…”

“…The model was verified with data obtained from a full scale facility. Sutton et al ( 1993) treated oily wastewater with a novel process train consisting of suspended growth biological treatment followed by ultrafiltration. The treatment scheme proved useful when a high degree of solids retention was required.…”

“…The most common treatment methods are settling [7], chemical destabilization (coagulation/flocculation) [8], centrifugation [9], flotation [10], filtration/coalescence [11], electrical methods [3,12], membrane processes [13][14][15][16][17][18][19][20], and vacuum evaporation [21,22]. Often a combination of several techniques is more efficient and cost-effective [23][24][25].…”

A coagulation-centrifugation/ultrafiltration hybrid process has been performed for the treatment of a commercial oil-in-water emulsion used in metalworking operations. The effect of pre-treatment stage on membrane fouling was evaluated to ascertain the main fouling mechanism and to establish the best membrane cleaning procedure. The hybrid process was optimized in terms of the maximum ultrafiltration (UF) permeate flux. Destabilization temperature, transmembrane pressure, feed flow rate to the UF module, and coagulant salt molar concentration were selected as factors. The experiments were designed using Taguchi method, and the contribution of each factor was determined using a statistical analysis of variance. Experimental results were also discussed in terms of environmental parameters (chemical oxygen demand [COD], conductivity, pH, and turbidity) for the main process streams. The best fit to experimental data of permeate flux decline corresponded to the cake/gel layer formation model. The cleaning procedure combined alkaline and acid washings with mechanical cleaning of membrane surface, and through this combination total permeate flux recovery was achieved. Temperature was the most significant factor affecting permeate flux, followed by coagulant salt concentration, with COD reductions higher than 97.5% for all experimental conditions tested.
