Abstract
Authors prepared TiO2 entrapped PVDF membranes (TiO2/PVDF) by adding varying amounts of TiO2 particles into the casting solution. They studied the catalytic property of TiO2/PVDF membranes for removing high concentrations of ammonia wastewater.
They investigated a number of factors affecting the removal rate of ammonia. These included crystal of TiO2, ozone dosage, catalyst dosage, residence time, pH value and reaction temperature. Results indicate that the rutile TiO2 has optimum removal effect for ammonia.
