Phosphate Recovery from Municipal Wastewater through Crystallization of Calcium Phosphate
نویسنده
چکیده
Phosphate concentrations in municipal and agricultural wastewaters continuously increase because of the growing use of detergents and fertilizers. Thus, it seems that phosphate recovery from wastewater as calcium phosphate would be attractive due to the vast applications of calcium phosphate in industry. In the current experimental study, the phosphate recovery by addition of calcium chloride to a synthesized wastewater was investigated under alkaline conditions. The crystallization experiments showed that using seed particles, the concentration of phosphorus can be reduced from 50 to 5.5 ppm in presence of ions of magnesium and carbonate as common impurities in wastewaters.

Modeling and Optimization of Phosphate Recovery from Industrial Wastewater and Precipitation of Solid Fertilizer using Experimental Design Methodology
Phosphorus (P) is one of the primary nutrients generating eutrophication in aquatic systems1. To prevent eutrophication, municipal or agricultural wastewaters are treated to reduce the phosphorus concentrations in the wastewater reaching surface water streams. While unregulated P is a pollutant in a water body, phosphorous is a useful resource in agricultural fertilizers, food supply, and indus...
متن کاملSeed selections for crystallization of calcium phosphate for phosphorus recovery.
Seed induces and promotes the crystallization of calcium phosphate, and acts as carrier of the recovered phosphorus (P). In order to select suitable seed for P recovery from wastewater, three seeds including Apatite (AP), Juraperle (JP) and phosphate-modified Juraperle (M-JP) were tested and compared. Batch and fixed-bed column experiments of seeded crystallization of calcium phosphate were und...
متن کاملSynthesis and Enhanced Phosphate Recovery Property of Porous Calcium Silicate Hydrate Using Polyethyleneglycol as Pore-Generation Agent
The primary objective of this paper was to synthesize a porous calcium silicate hydrate (CSH) with enhanced phosphate recovery property using polyethyleneglycol (PEG) as pore-generation agent. The formation mechanism of porous CSH was proposed. PEG molecules were inserted into the void region of oxygen-silicon tetrahedron chains and the layers of CSH. A steric hindrance layer was generated to p...

Nitrate and phosphate are abundant in urban wastewater. We evaluated the efficiency of nitrate and phosphate removal from wastewater by Scenedesmus obliquus and its use as a medium for Scenedesmus obliquus. Samples were collected from the effluent of central wastewater treatment in Gorgan. This experiment was done by 3 treatments and 6 replications that effluent with 100%, 50% and 0% were dilut...
