Date: 2020-08-28Read: 6
Membrane separation test device
This device is an experimental equipment designed for various researchers to conduct membrane separation experiments. It is equipped with one or two small roll type membrane modules, which can be used in series or parallel with single or double modules; By replacing membrane components of different specifications, low-pressure reverse osmosis, nanofiltration, ultrafiltration, and microfiltration tests can be conducted separately. The feature is that the system is compact, compact, and easy to operate on the desktop; No leakage, low liquid flow rate; Adopting imported standard membrane components with reliable performance; Convenient component replacement and easy experimental operation. This equipment is mainly used to determine the technical process parameters for material liquid separation and purification, as well as the selection of membrane materials and membrane types, to determine the effect achieved by membrane separation, and to provide design basis for industrial systems.
Characteristics of membrane separation test device
This device is equipped with complete process parameter detection instruments, and the system is equipped with a flow display and metering system - concentrated water (liquid) flow rate, product water (clear liquid) flow rate; Conductivity detection indicator instrument - measures the conductivity of raw water (liquid) and pure water (permeate), as well as the working temperature parameters of the liquid; Work pressure indicator instrument. The shell is made of stainless steel frosted plate, which is beautiful and hygienic.
Various roll type membrane elements such as reverse osmosis, nanofiltration, ultrafiltration, and microfiltration can be installed according to experimental needs for the concentration, desalination, separation, purification, clarification, sterilization, and purification of feed liquids. They can be widely used in pharmaceutical, food and beverage, chemical, plant extraction, biological agents, environmental water treatment, and other fields, especially suitable for universities, research institutions, enterprise R&D centers, and small-scale production.
Our company can provide imported membrane components and membranes with various materials and molecular weight cut-off according to user needs. We can also provide you with laboratory pure water and ultra pure water equipment, as well as membrane separation equipment for reverse osmosis, nanofiltration, ultrafiltration, and microfiltration in both Chinese and industrial production scales.

Types and Applications of Nanofiltration Membrane
Nanofiltration membrane (NF) is a special and promising type of separation membrane, with a molecular weight cut-off of approximately 80-1000 and a pore size of about 1 nanometer. The surface separation layer of nanofiltration membrane is composed of polyelectrolytes, which have electrostatic interactions with ions and therefore have a certain retention rate for inorganic salts.
