Working at thermophilic conditions instead of mesophilic, and also the addition of a co-substrate, are both the ways to intend to improve the anaerobic digestion of the source-collected organic fraction of municipal solid wastes (SC-OFMSW). Addition of sewage treatment plant fat, oil and grease wastes (STP-FOGW), that are nowadays sent to landfill, would represent an opportunity to recover a wa...

This study investigated the potential benefit of co-digesting sewage sludge (SS) and settled/mixed fat, oil, grease (FOG) with BioAmp pretreatment, a bio-additive product, for utility. was found to increase soluble chemical oxygen demand (SCOD)/COD ratio FOG (from 4.19 4.49), consequently enhancing volatile solid (VS) reduction 75.9 84.8%). The SS co-digestion based on their actual daily produc...

The wide spread of food outlets has become an environmental and sanitation infrastructure problem, due to Fats, Oils and Grease (FOG). A grease box is used at the industrials facilities to collect the FOG, in a specific time window, while its quality is good for recycling (e.g., biodiesel) and it is economically valuable. After this period, it will be disposed at a cost. For the proper manageme...

Abstract The permanganate index (PI), oil and grease (O&G), 17 polycyclic aromatic hydrocarbons (PAHs) were analyzed in surface sediment water samples collected at 13 sites along the western coast of Suez Bay (SB). PI O&G SB coastal seawater ranged from 9.6 mg O 2 l −1 17.0 to 16.0 37.0 , respectively. level (PAH) offshore area was determined by gas chromatography/flame ionization detec...

The rheological characteristics of one mineral oil and two ionic liquid (IL) based lubricating greases were explored as a function of thickener concentration. The ILs used are 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMIM][TFSI]) and trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide ([P6,6,6,14][TFSI]), with polytetrafluoroethylene (PTFE) particles used as t...

This paper discusses nitrogen removal mechanisms in an aerobic membrane bioreactor (MBR) treating high strength pet food wastewater characterized by oil & grease, COD, BOD5, TSS, TKN, NH4-N concentrations of 2800 mg/L, 25000 mg/L, 10000 mg/L, 4500 mg/L, 1650 mg/L and 1300 mg/L respectively. An MBR operating at SRT >25 days achieved mixed liquor total suspended solids (MLTSS) concentrations >300...

In this study polyethersulfone ultrafiltration membrane were prepared with the modifier gelatin at 0, 5, 10, 15 and 20 wt % using DMF as solvent by phase inversion process. Morphologies and characteristics of the membranes were investigated through the methods of SEM, XRD, contact angle measurements. The performance of the modified membrane for the treatment of leather and distillery wastewater...
