Removal of Organic Matter by Activated Carbon Columns

Journal of the Environmental Engineering Division, 1974
This study shows that the major organic fraction in activated sludge effluent that exhibited a high adsorption in activated carbon columns is a fulvic acid-like material with a molecular weight ranging from approximately 100 - 10,000. A high molecular compound with a molecular weight larger than 50,000 absorbed poorly in carbon columns.

Column Studies of Micropollutant Removal from Wastewater

2014
Production of systems for onsite treatment of wastewater is an expanding industry fostering more widespread application of reuse technology. This study evaluated the potential for constructed wetlands to remove micropollutants from industrial and household sources and, thereby, reduce their environmental impact resulting from toxicity, endocrine ...

Entrainment Removal by Raschig Ring Packed Column Separator

Chemical engineering, 1970
ラシヒリング充填塔による蒸発缶からの同伴飛沫除染特性を塔内径124mmの実験塔を用いて, 水蒸気-水系で測定した。充墳物としては1/2-in, 磁製ラシヒリング等を用い, 単位蒸気量あたりの同伴飛沫量が10-4～10-5の条件で, 主として充填層高Z (10～40cm), 空塔蒸気速度μ1 (0.6～1.7m/sec) が充填塔の除染係数 (D. F.) におよぼす影響について検討を行なった。その結果 (D. F.) はμ1≧～1.0でほぼ一定値となること, z≧20では除染性能が類似することが明らかになった。

Effect of soil permeability on virus removal through soil columns

Applied and Environmental Microbiology, 1981
Laboratory experiments were performed on four different soils, using 100 cm long columns, to determine the extent of virus movement when wastewater percolated through the soils at various hydraulic flow rates. Unchlorinated secondary sewage effluent seeded with either poliovirus type 1 (strain LSc) or echovirus type 1 (isolate V239) was continuously ...

Phosphate Removal from Sewage Water by Soil Columns

Journal of Environmental Quality, 1977
AbstractPhosphate (PO4‐P) removal from secondary sewage effluent by calcareous sand columns was proportional to the infiltration rate. Phosphate concentrations in drainage from columns, packed with a mixture of sand from recharge basins and sand never previously exposed to sewage water, were below 1 ppm for over 200 days, increased, and finally leveled
