Silica Sol Ceramic Membrane Concentration System | High Efficiency · Corrosion & Temperature Resistance · Breaking Concentration Bottlenecks

In the production of silica sol, traditional vacuum dehydration and organic ultrafiltration membrane concentration processes suffer from high energy consumption, low efficiency, and rapid membrane degradation. Leveraging its independently developed inorganic ceramic membrane technology, Shandong Qisheng Membrane Separation has launched a dedicated concentration system for silica sol that breaks through conventional concentration limits, enabling high-concentration, high-efficiency, and low-cost continuous production.

Technological Breakthrough

Organic Ultrafiltration Membrane Limits: Concentration is limited to only 30%; at higher concentrations, membrane elements are prone to damage and require frequent replacement.

Qisheng Ceramic Membrane Advantage: Concentration can reach over 40%; offers excellent wear resistance, easy cleaning, rapid flux recovery, and extended service life.

Technical Advantages

High Concentration Efficiency, Exceeding 40% – Ceramic membranes withstand high pressure and fouling, supporting silica sol concentration to high solids content, significantly improving batch processing capacity.

Superior Stability and Extended Service Life – High mechanical strength, resistance to acids, alkalis, and high temperatures, with excellent anti-fouling performance. Membrane elements can be repeatedly cleaned and regenerated.

Energy Savings and Low Overall Costs – Concentration requires no phase change, with significantly lower energy consumption compared to thermal concentration. Simple maintenance eliminates the need for frequent membrane replacement.

Clean Production and Quality Enhancement – Simultaneously removes water and suspended particles, improving silica sol purity and stability. The clean permeate can be reused.

Qisheng Ceramic Membrane Systems have been successfully deployed in numerous silica sol concentration projects, providing customers with reliable, efficient, and scalable membrane-based concentration solutions.
