Textile plant wastewater toxicity

Abstract

In mid-1974 and mid-1976, two U.S. Environmental Protection Agency (EPA) regulatory events occurred which led to a large research effort designed to evaluate the toxicity of textile plant wastewaters, and to

PDMS/PVDF hybrid electrospun membrane with superhydrophobic property and drop impact dynamics for dyeing wastewater treatment using membrane distillation

“…The purpose of this study is to investigate how the hydrophobic PDMS microspheres coated on a basic electrospun poly(vinylidene fluoride-co-hexafluoropropene) (PVDF-HFP) (E-PH) membrane does improve anti-wetting and antifouling property of the membrane. Dyeing wastewater is chosen as a feed solution for MD since at present the amount of dyeing wastewater emitted is being increased and its complex composition has made it one of the largest contributors to water pollution [16][17][18]. To date, limited researches have been conducted on MD fouling in treating dyeing wastewater.…”

High flux and antifouling properties of negatively charged membrane for dyeing wastewater treatment by membrane distillation

“…Because of the increasing use of chemical synthetic textiles in recent years, dye wastewater has become one of the largest contributors to pollution (Hao et al, 2000;Rawlings and Samfield, 1979;Vanhulle et al, 2008). Textile production requires an extremely large amount of water, which is discharged as wastewater containing high concentrations of reactive dye, chemical residues and low-biodegradable materials, with high levels of chemical and biochemical oxygen demand (COD and BOD, respectively) (Basava Rao and Ram Mohan Rao, 2006;Hu and Wang, 1999;Lin and Chen, 1997).…”

A randomized controlled evaluation of absorption of silver with the use of silver alginate (Algidex) patches in very low birth weight (VLBW) infants with central lines

“…Other sources of silver release to surface waters include textile plant wastewater effluent (Rawlings and Samfield 1979); petroleum refinery effluents (Snider and Manning 1982); and quench water and fly ash scrubber water effluents from municipal incinerators (Law and Gordon 1979). Silver was detected in 7 of 58 (12%) samples from the National Urban Runoff Program survey (Cole et al 1984).…”
