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...

Staphylococcus aureus D4508, obtained from a patient with nonmenstrual toxic shock syndrome (TSS), produced enterotoxin A while not making other known enterotoxins or TSS toxin 1. Concentrated culture fluids of the organism, administered subcutaneously in miniosmotic pumps, induced TSS-like symptoms (four of six animals succumbed). Identical culture fluids pretreated with anti-enterotoxin A ser...

The impact of anthropogenic activities on coastal waters is a cause of concern because such activities add to the total suspended sediment (TSS) budget of the coastal waters, which have negative impacts on the coastal ecosystem. Satellite remote sensing provides a powerful tool in monitoring TSS concentration at high spatiotemporal resolution, but coastal managers should be mindful that the sat...

Suspended solids removal performance of a manufactured stormwater treatment device varies greatly with operating conditions and laboratory or field evaluation techniques. Laboratory testing and field monitoring protocols have been established to evaluate the performance (removal efficiency or effluent concentration) of manufactured stormwater treatment devices and other structural BMPs. However...

The capacity of a membrane biological reactor to provide nitrification, denitrification, and enhanced biological phosphorus removal of a high-strength aquaculture backwash flow (control condition), or the same flow amended with 100mg/L of NO(3)-N and 3mg/L of dissolved P (test condition), was assessed using only endogenous carbon. Permeate TSS and cBOD(5) concentrations were <1mg/L under contro...

In Colorado, USA, diagnoses coded as toxic shock syndrome (TSS) constituted 27.3% of infectious shock cases during 1993-2006. The incidence of staphylococcal TSS did not change significantly overall or in female patients 10-49 years of age but increased for streptococcal TSS. TSS may be underrecognized among all ages and both sexes.

Creative solutions to manage stormwater include ecologically based designs, such as biofilter structures. A laboratory experiment was established study the ability of biofilters remove nutrients, metals, total suspended solids (TSS), and organic C originating from roadside melted snow. Special attention paid removal P. In addition, fate microplastics (MPs) in followed. The materials selected fo...

background: olive oil wastewater  contains chemical contents and organic materials that are resistant to biodegradation.  the existence of phenolic inhibitor compounds, toxicity to microorganisms in wastewater treatment units, unpleasant odor, high biochemical oxygen demand (bod) and chemical oxygen demand (cod), high suspended solids, and compounds resistant to biodegradation in such wastewate...

Rock filters are an established technology for polishing waste stabilization pond effluents. However, they rapidly become anoxic and consequently do not remove ammonium-nitrogen. Horizontal-flow aerated rock filters (HFARF), developed to permit nitrification and hence ammonium-N removal, were compared with a novel vertical-flow aerated rock filter (VFARF). There were no differences in the remov...
