Abstract

Abstract

Hydrocyclone separators have advantages of high separation efficiency, simplicity, reliability and low cost, which has been widely used in various separation scenarios, especially in wastewater treatment in recent years. This article reviewed the operating parameters (feed flow rate, feed concentration, feed pressure), structural design parameters (overflow pipe insertion depth, underflow pipe diameter, reflux angle) and configuration types (W type, parabolic type, completely cylindrical type) on the hydrocyclones separation performance. Optimizing the operating parameters could enhance the separation efficiency; the flow field generated when the ratio of overflow pipe insertion depth to cylindrical cross section diameter (L₀/D) equaled 1.0 was conducive to separation; the underflow pipe diameter had an optimal range; combining with water source heat pump, the optimal suction angle was 90°. The recent progress of hydrocyclone research and application included promoting microbial aggregates (including increasing sludge hydrolysis rate and improving sedimentation performance), separating specific particulate microorganisms (including anaerobic ammonia oxidizing bacteria granular sludge) and removing or recovering substances with specific density (including suspended organic matter, mud sand, metal particles), which opened up new perspectives for hydrocyclones future application in wastewater treatment.
