Ceramic membranes are porous asymmetric membranes made by high-temperature sintering of materials such as alumina and zirconia through special processes.Ceramic membrane equipment is a "crossflow filtration" type of solid-liquid separation process. Under pressure, the feed liquid flows within the membrane tubes, with small molecules permeating the membrane while large molecules and solids are retained in the membrane to form a concentrated liquid, achieving the objectives of separation, concentration, and purification of fluids. The filtration precision of ceramic membranes encompasses microfiltration and ultrafiltration, with microfiltration membrane pore sizes ranging from 50nm to 1.4m, and ultrafiltration membrane precision ranging from 8KDa to 50KDa. Different pore-size membranes can be selected as needed to achieve clarification and separation. Ceramic membranes feature high-temperature resistance, chemical corrosion resistance, high mechanical strength, microbial resistance, high flux, good cleaning recovery, and long service life. They are currently used in fermentation liquid clarification, oil-containing wastewater treatment, MBR for waste leachate, oilfield water injection, juice, fruit wine, vinegar, and more.
I. Function and Application of the Experimental Machine
This unit is a small-scale membrane separation device for laboratory use, including ultrafiltration, nanofiltration, and reverse osmosis, and can be widely applied in the separation, concentration, and purification of substances; the industrialization concept runs through the design process of the equipment, suitable for researchers to explore various process parameters required for the industrial scaling-up of the equipment.
Two,Features of the Experimental Machine
The overall structure is compact, operation is simple, stability is excellent, the appearance is aesthetically pleasing, and the entire unit is made of stainless steel.
The power section utilizes a hydraulic diaphragm pump, offering high lift and stable pressure with reliable performance.
● The system high-pressure piping is made of sanitary-grade stainless steel, offering high pressure resistance and corrosion resistance. Connections are made with sanitary grade clamp-style fittings, ensuring convenient and reliable assembly.
The system includes pressure and temperature protection devices. The pressure protection device can automatically alarm and shut down when the pressure exceeds the safe limit; the temperature protection device can automatically alarm and shut down when the temperature goes beyond the limit; the safety filter device can prevent system damage caused by the entry of solid particles.
The equipment employs various technologies identical to production-line equipment in controlling parameters such as pressure, temperature, flow, and flow rate, making the separation work in the laboratory more akin to the actual industrial situation, which is conducive to the industrialization of the process.
● The equipment utilizes variable frequency control, effectively expanding its application range; the system's processing capacity is 0-150L/hour (which is related to the properties of the material), with a circulating volume of only 350-400ml, making it particularly suitable for laboratory use.
