Nanofiltration is a membrane separation technology that falls between ultrafiltration and reverse osmosis, with a retention molecular weight ofIn the range of 200-1000 nanometers, the membrane has an aperture size of a few nanometers. Since this membrane retains molecules larger than about 1 nanometer with a greater than 95% efficiency during the filtration process, it is called nanofiltration. Owing to the superior characteristics of nanofiltration separation technology, it shows great application prospects in various fields such as pharmaceuticals, biochemical engineering, and food industry. One significant feature of nanofiltration membranes is that the membrane itself is charged, which is an important reason why it still has high desalination performance at low pressure and can remove inorganic salts from membranes with a molecular weight cut-off of hundreds. We offer a variety of compact, rolled nanofiltration membrane elements with a reasonable surface area/volume ratio. By using different channel grids (13-120 mil), the width of the feed stream channel can be adjusted to accommodate fluids of various viscosities. To meet the requirements of certain special industries, we can select the appropriate nanofiltration membrane based on the customer's process requirements, the characteristics of the treatment system, and relevant technical specifications.
I. Membrane Separation Experimental Equipment - Functions and Applications
This unit is a small-scale membrane separation equipment for laboratory use, including ultrafiltration, nanofiltration, and reverse osmosis, which can be widely applied in the separation, concentration, and purification of substances; the industrialization concept runs throughout the design process, making it 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 machine is made of stainless steel.
The power section utilizes a hydraulic diaphragm pump, offering high lift, stable pressure, and reliable performance.
● The high-pressure piping system utilizes sanitary-grade stainless steel, offering high pressure resistance and corrosion resistance. Connections are made with sanitary clamp-style fittings, providing easy and reliable assembly.
The system includes pressure and temperature protection devices. The pressure protection device can automatically trigger an alarm and stop operation when the pressure exceeds the safe limit; the temperature protection device can automatically trigger an alarm and stop operation when the temperature goes beyond the allowable limit; the safety filter device can prevent system damage caused by the entry of solid particles.
The equipment employs various technologies similar to those in production equipment for controlling parameters such as pressure, temperature, flow rate, and velocity, making the separation work in the laboratory more akin to industrial实际情况, conducive to the industrialization of the process.
The equipment features variable frequency control, effectively expanding its application range; the system's processing capacity is 0-150L/hour (capacity is related to the properties of the material), with the minimum circulation volume as low as 350-400ml, making it particularly suitable for laboratory use.
