Ultrafine powder concentration and recovery

(Summary description)


Technology Introduction

Solid-liquid separation of particle suspension system is a common unit process in chemical process, involving purification of raw materials and products, recovery of valuable ultra-fine products in wastewater, separation of fine particle catalysts from raw materials or products, etc. Due to the small particle size of the powder, powder washing and separation is the difficulty of its industrialization. Nano-scale powder can be intercepted, washed and concentrated by ceramic membrane technology. Greatly improve product stability and yield.
