removal of 1 4 dioxane using activate carbon

A study on removal of 1,4-dioxane in drinking water by …

2005. 4. 25. & 0183;& 32;Abstract. Recently, 1,4-Dioxane is known as the contaminant in water plants in Korea. Owing to its toxicity and potential health effect, 1,4-Dioxane must be determined at very low levels in drinking water. Studies on the removal of 1,4-Dioxane in drinking water were performed by using multi filtration system with activated carbons and membrane filter.

2020. 2. 5. & 0183;& 32;Fukuhara et al. 2011 investigated the 1,4-dioxane adsorption by eight types of activated carbon AC in water and reported that sawdust-based AC gave the best adsorption of 1,4-dioxane. We also examined the adsorption of 1,4-dioxane from water by three types of AC and found that wood-based AC is suitable for 1,4-dioxane removal Nomura et al., 2016 .Cited by: 16

Promoted ozonation for the decomposition of 1,4-dioxane …

2016. 9. 29. & 0183;& 32;For adsorption, 4% and 31% of 1,4-dioxane could be removed with 1 g/L and 3 g/L activated carbon after 40 min, respectively. Considering that the final removal of 1,4-dioxane by activated carbon adsorption was still low, the coupling of ozone and activated carbon was used to enhance the degradation efficiency.

FRTR December 6, 2006 5 PARSONS EMSI PERFORMANCE Treatment train cannot remove 1,4-dioxane to below permit 2.0 ppm due to poor UV transmittance, hydroxyl scavenging with NTES waters, and poor sorption on GAC Other permit parameters can be met by GAC alone Evaluated a number of technologies:

Removal of 1,4-dioxane from wastewater - ScienceDirect

1986. 4. 1. & 0183;& 32;Removal of 1,4-dioxane and organic carbon during hydrogen peroxide oxidation. To determine whether 1,4-dioxane was completely oxidized during the reaction, samples of the test solution containing 12 moles H202 per mole compound were periodically analyzed for the concentration of organic carbon remaining in solution.

Removal of 1,4-Dioxane in Water Using Specific Microbe …

2019. 5. 10. & 0183;& 32;A cell-entrapped carrier based on polyethylene glycol diacrylate was prepared using enriched culturing of Candidatus Saccharibacteria, using 1,4-dioxane as the only carbon source in activated sludge. When the 1,4-dioxane concentration was 5 mg/L, the cell-immobilized carrier process removed up to 0.026 mg/L of 1,4-dioxane at a hydraulic retention time HRT of 6 h, but the activated sludge process was removed …
