The technology still needs further development because of issues including: (1) different ,sludge, ages between the nitrifying bacteria and the phosphate-accumulating organisms (PAOs), which cause their competition for matrix (Thomas et al. 2003); (2) unstable P removal efficiency, which leads to the effluent quality not meeting the discharge standard; therefore, it becomes common in practice that the effluent …

It can be used for the treatment of drinking water, industrial water, sewage and ,sludge,. Compared with other inorganic flocculants, PFS can form stable flocculants in the pH range of 5-11, with fast settling speed, good water purification effect, no harmful substances such as aluminum, chlorine and heavy metal ions, and no water phase transfer of iron ions, which will not cause secondary ...

The LLE of phosphorus from sulfuric ,acid, solution by using benzyl dimethyl amine (BDMA) in kerosene has been investigated in this study. Although a few studies used BDMA to remove phosphorus from ,wastewater, [9, 18], they were not systematic and did not deal with solutions with high phosphorus content (dealt with only 30 mg·L −1).

2018). When the hypochlorite dissolved in water, hypochlorite ,acid, (HOCl) would be rapidly generated (Eq. (1)). On one hand, the formed hypochlorous ,acid, is unstable in the liquid phase, which would be fur-ther decomposed into OCl− (Eq. (2)).

Because it is hard to achieve perfect magnetic separation, we estimated the amounts of CaO and FeO required as ,dephosphorization, agents and the amount of slag generated on the assumption that 60% of the phosphorus‐rich phase and 10% of the residual slag are recovered as phosphorus resources, and that the residues that are formed from the remaining 40% of phosphorus‐rich phase and 90% of ...
