Large-Eddy Simulations of Hydrocyclones
… and particle classification process in hydrocyclones using large-eddy simulations of turbulent multiphase flow. Two types of hydrocyclones are considered. The first is a classifying hydrocyclone, and the second is a mineral flotation hydrocyclone, also known as an air-sparged …

Improving settleability and achieving biological phosphorus removal through the application of sidestream gravimetric selectors
This project utilizes hydrocyclones in wastewater treatment to select for heavier solids, and has been used before in multiple small-scale systems. This is the first implementation of hydrocyclones in a full-scale plant for the purpose of increased settleability, while also achieving enhanced …

Investigating the potential of using hydrocyclone-fine screen hybrid systems to improve the performance of classification circuits
… that controls the performance of the circuit. Hydrocyclones are normally used to perform the classification function. They offer numerous advantages that include, the ability to handle high throughputs, low floor space occupation and relatively low capital and running costs. Despite these …

Hydrocyclone Implementation at Two Wastewater Treatment Facilities To Promote Overall Settling Improvement
… facilities experiencing poor settleability. Hydrocyclones are fed mixed liquor through the feed inlet and experience a centrifugal motion that separates solids based on density. The variation in hydrocyclone nozzle sizes will report different calculated hydraulic and mass split percentages …

Improvement to hydrocyclone used in separating particles from produced water in the oil and gas industry.
… fluid flows in liquid-liquid and solid-liquid hydrocyclones were analysed using different geometrical parts, which established that - as reviewed in the literature - the geometrical parts cannot be used to effectively separate particles less than 10μm. A comparison of the fluid flows in …

Monitoring an industrial hydrocyclone using frequency domain multiplexing electrical impedance tomography
… in research for optimisation and control of hydrocyclones, as industries consistently demand new and more cost effective ways of production. In an industrial setup, it is very difficult to determine the optimal operating point of a hydrocyclone. Tomography offers an exceptional opportunity to …

A mathematical model for predicting classification performance in wet fine screens
… such as closed circuits with a mill in place of hydrocyclones. However, even though developments are increasing, there has been a process model developmental lag. A fine wet screen model that can be used for unit simulation purposes to predict screen performance outcomes or integration into other …

The effect of circuit configuration on regrind circuit performance
… between these configurations is the network of hydrocyclones. This study pays special attention to the effect of cyclone performance on the regrind circuit performance. Comparisons were made between the open and the 2-stage closed circuits in three concentrators, and surprisingly the closed …

Gravity selector-enabled kenaf recirculation and reuse as a renewable ballasting agent for sludge settleability enhancement in a municipal wastewater secondary process: A real wastewater pilot-scale study
… be achieved while drawing on the strength of hydrocyclones to retain and return the ballasting agent. This idea was tested by dosing kenaf, a plant-based renewable migrating carrier in a pilot-scale plug flow reactor equipped with a gravity selector to mimic a hydrocyclone. Results showed that …

Evaluation of Novel Fine Coal Dewatering Aids
… (150 micron x 0) by means of 6-inch diameter hydrocyclones. The cyclone overflows are stored in fine coal impoundments, which create environmental concerns and represent loss of valuable national resources. The major component of the high costs of cleaning fine coal is associated with the …

Assessing the effect of cone ratio, feed solids concentration and viscosity on hydrocyclone performance
… of varying degrees of liberation and size. Hydrocyclones are commonly used to classify these particles. If the classification stage is not efficient, both grinding and flotation cannot be optimised or operated efficiently. Ores that are mined in industry contain metals of varying specific …
