“…The crystalline phosp rus, linked to the fine-grained PG, can be eliminated by classification. The impurity moval efficiency can be regulated by adjusting the operation parameters, such as the tling mouth's diameter and the feed's flow rate [61]. Tan et al [62] explored the impurity removal effect of cyclones on PG.…”

Phosphogypsum (PG), a byproduct during the phosphoric acid production process, also known as the wet process, contains complex and diverse impurities, resulting in low utilization and considerable accumulation. This leads to a massive waste of land resources and a series of environmental pollution problems. Given the current urgent ecological and environmental situation, developing impurity removal processes with low energy consumption and high efficiency, exploring valuable resource recovery, preparing high value-added PG products, and broadening the comprehensive utilization ways of PG are significant strategies to promote the sustainable consumption of PG and sustainable development of the phosphorus chemical industry. This review comprehensively summarizes the advantages and disadvantages of existing PG impurity removal and utilization technologies and probes into the future development direction, which provides references and ideas for subsequent PG research.

“…Hydrocyclones are used along with other technologies as a pre-treatment methods which can remove patricles in the range of 5-15 µm (Drewes et al, 2009). The technologies has a long lifetime and do not necessitate the pre-treatment of feed water but main drawback of this method is the generation of vast slurry of intense solid waste (Niazi, Habibian, & Rahimi, 2017).…”

The produced water (PW), which could be a confounding blend of different natural and inorganic mixes (generally salts, minerals and oils) is a noteworthy wastewater stream formed during petroleum generation forms. With the worldwide interest and production of petroleum derivative (oil and gas) increment, the produced water generation likewise increases similarly. Previously, PW was just re-injected into the unfilled well after extraction. As freshwater deliver turns out to be gradually rare, PW can turn into a significant water source after suitable treatment. There are different physical and substance strategies to treat the PW. Nonetheless, a thorough and thoughtful understanding of each issue can prompt a higher and progressively productive arrangement. In this investigation, different physical and chemical treatment techniques for PW have been checked on dependent on the most recent detections and as of late distributed articles on this topic. Moreover, difficulties and chances of every one of these treatment plans have been completely discussed. In expansion, possible applications for reprocessing the treated PW have been recommended and talked about at long last.

“…Hydrocyclones, which are widely used in various areas, including mineral processing, petrochemicals, environmental protection systems, and biological systems, are used for the separation of nonhomogeneous mixtures via centrifugal sedimentation. − These devices have the advantages of simple structures, nonmovable parts, and low investment costs, among others. In mineral processing, hydrocyclones are mainly used for classification, sorting, designing, and thickening, in addition to other functions. , Within hydrocyclones is the separation behavior of particles under the influence of centrifugal force, gravity, buoyancy, drag, etc., which is a highly developed turbulent movement, the internal hydrodynamic properties and particle movement behaviors are extremely complicated. − Because of their structural limitations, the separation process inevitably involves particle misplacement of overflow and underflow, which is usually characterized by reductions in the recovery yield and quality of the target products.…”

Two cylindrical section hydrocyclones can suppress particle misplacement by regulating the circulation flow, but few researchers have investigated the effect of the cylindrical height ratio. In this paper, numerical simulations and physical tests were conducted to investigate the effect of height ratio on the particle motion behavior and separation performance of the two cylindrical section hydrocyclone. According to the numerical simulation results, with increasing height ratio, the separation cut size decreased, the separation accuracy and recovery rate of medium and coarse particles in the underflow increased, the coarse particle misplacement in overflow decreased significantly, and the proportion of medium particle circulation flow gradually increased. According to the test results, the number of misplaced fine particles in underflow could be effectively reduced when H 1 /H 0 = 0.30. With increasing height ratio, the number of misplaced coarse particles in the overflow decreased and the classification efficiency of fine particles increased. The maximum separation efficiencies of medium and coarse particles could be obtained at H 1 /H 0 values of 0.47 and 0.17, respectively. Therefore, increasing the height ratio could inhibit coarse particle misplacement in overflow and improve the separation performance of two cylindrical section hydrocyclones.
