In the pretreatment for solid–liquid separation of sewage, traditional hydrocyclone cannot reasonably achieve a high underflow concentration and efficiency at same time. An intermittent discharge concentrated was proposed in this paper to solve problem. order determine specific performance hydrocyclone, studied influence structure parameters process on its through experimental testing. The resu...

There are many factors that affect the separation performance of hydrocyclone, including structure feed body, but mechanism influence internal flow field hydrocyclone on Axial Velocity Wave Zone (AVWZ) is not yet clear. Based numerical test method, this paper analyzes body and particle distribution characteristics AVWZ its relationship with performance. The results show structural parameters in...

Due to rising oil price and environmental aspects, research on alternatives for petroleum based chemicals and fuels is growing in recent years. Biomass is one potential raw material for producing non-petroleum derived chemicals and fuels. Different catalysts and reaction steps are required to generate the same products in comparison with the petroleum based processes. One possible starting mate...

Turbulence analysis of flow inside a hydrocyclone is carried out using commercially available CFD software ANSYS-CFX (release 11.0). Commercial CFD software(s) and their turbulence models have come a long way in accurately predicting the flow inside a hydrocyclone, both at the mean as well as at the turbulence level. Previous studies have shown, the more accurate the turbulence prediction is, t...

Sustainable development and environmental protection require green products, processes, and waste management strategies. The selection and design of green and clean processes and products involve handling a huge set of data related to the environment, economics and technologies. Therefore, it is essential to employ a comprehensive technique to guide decision-making under uncertainty that can in...

many studies have considered the effects of suspension properties on the dewatering process but fewhave focused on ore properties. thus, the present work studied the effects of ore properties (density,particle size, mineralogy) on the dewatering process based on lab and pilot experiments. a hydrocyclonewas used to prepare the required samples for the experiments. to study the effects of mineral...
