The removal of dissolved organic carbon (DOC) is a key factor in the control disinfection by-product (DBP) formation drinking water. Ion exchange process deals with naturally negatively charged matter. A fluidized bed column test has been chosen to parallel efficiency 4 different anionic resins (Purolite PPA860S, Dowex TAN-1, Amberlite IRA-958 and IRA-410) terms DOC fraction related DBP reducti...

Ozone pre-oxidation can effectively degrade MC-LR, 2mg / L ozone for MC-LR removal efficiency of 65.28%. 2mg / L ozone for MC-LR removal efficiency reach to 65.28%. Ozone also has a better removal effect for turbidity and UV254 , 4mg / L ozone for UV254 and turbidity removal efficiency are 50% and 59.38%. But ozone removal efficiency of TOC and CODMn was poor, 3mg / L ozone for TOC and CODMn re...

Wastewater discharge from textile industries concern environmental risks. Superiority of microbial methods over other high cost combined includes conversion persistent organic materials to non-toxic last materials, sustainability, low cost, and comfortable. Textile wastewaters can have opposite effects on the quality water in total carbon (TOC) Chemical oxygen demand (COD). Agitation cultures r...

An estimation of the organic content of water has been used for some time as an indicator of water qual i ty (E.P.A. 1975). The carbon adsorption method (CAM) was developed in 1951-52 for this purpose but is no longer recommended (CAPELLI et al . 1977, OTSON et al . 1979). With recent improvements in analytical instrumentation, total organic carbon (TOC) determinations are being used to assess ...

The objective of this study was to investigate powdered activated carbon (PAC) contribution to natural organic matter (NOM) removal by a submerged MF and UF hybrid systems. It was found that filtration of surface waters by a bare MF and UF membranes removed negligible TOC; by contrast, significant amounts of TOC were removed when daily added PAC particles were predeposited on the membrane surfa...

[1] Flow-weighted dissolved organic carbon (DOC) concentrations and dO values were determined from major arctic rivers, specifically the Ob, Yenisey, Lena, Kolyma, Mackenzie, and Yukon during 2003–2004. These data were considered in conjunction with marine data for DOC, dO values, nutrients, salinity, and fluorometric indicators of DOC obtained during sampling at the shelf-basin boundary of the...
