Flotation reaction was not affected by pH. Flotation efficiency decreased with increasing ionic strength and in the presence of sulfate. However, the depressed flotation could be improved by increasing SDS concentration. 展开 关键词: Waste water purification Industrial waste water Electronics industry ...
The efficiency of Alum as a coagulant to remove fluoride from water was investigated. The effects of chemical dosage of coagulant in different PH and mixing speed, initial amount of fluoride, to remove fluoride are studied. Experimentsinthree stages, includingselecting the best dose, best PH and...
F and Cl removal efficiency with L/S ratio increased from 2:1 to 4:1. Considering filtration and wastewater treating, L/S 3:1 were chosen for all further experiments. Table 3 Effect of L/S ratio on F and Cl removal efficiency
