Detailed description

Product Overview
ultrafiltration and nanofiltration membrane separation technology is a cross-flow filtration type of separation in this filtering process, the flow direction of the feed solution and concentrate are parallel with the membrane so that the membrane surface is not easy to deposit particles filter holes can not easily be Blocking, so the filter can be long-term, repeated use. The roll type membrane separation device is the main type in the cross flow separation and filtration equipment.
Characteristics of the equipment
from the United States Millipore (China) Co., according to the company specializes in the production of technical requirements HW type, SMH type, HPL type membrane has the following features:
Complete product specifications 1, there is little to separate the ability to have a molecular weight cut 200 NF grade Separation, as large as 200,000 cut molecular weight of the ultrafiltration separation level, a variety of filter material, to choose from. Equipment size is small to an area of 0.6m2 membrane experimental device, large to several hundred square meters of membrane area of industrial-scale production of complete sets of devices.
2 for the use of many projects to meet the purified water, water purification, liquid products, clarification and purification, semi-finished product concentration, and desalination. Removal of small molecular weight organic solvents and other types of process requirements.
3 in the extract of Chinese herbal medicine to remove macromolecules, purified liquid, part of the decolorization and so has a unique effect, and low energy consumption, high separation rate, solid-liquid separation is irreplaceable device. Pre-sale and after-sales service improvement, including the provision of technical advice to help carry out the application test and on-site installation, commissioning until the project contracting and other technical services.

selection should be based on actual user requirements, choose different specifications of film Device.
2 Membrane element: Membrane element is the key component of the membrane separation device, the fluid enters the material circulation layer, flows along the film surface parallel direction, passes through the membrane filtration fluid in the diversion layer in the predetermined direction to enter the central filtrate tube Outflow component. The liquid material is concentrated and flows out from the other end of the membrane element. In actual operation, this separation process is iterated and cycled until a predetermined process requirement is reached.
3 Components: The membrane components into the stainless steel container, placed between the container membrane membrane components, the external configuration of the necessary connection pipe, constitute a separate membrane separation, which is the membrane separation device basic unit.
4 devices: membrane separation device by the components, pipes, racks, booster pumps, containers, control box and protection filters and other components.
Components are the basic components, the size and size of the entire device depends on the size and number of components. The components are arranged in a vertical or horizontal order on the rack.
Pipes, including valves, pipes, live access, links, elbow and other fittings, the components connected into one. The pipe diameter is determined by calculation. Some devices are arranged in the pipeline is positive and negative flow system, is conducive to out of the membrane inside the retentive material to keep the flow of patency and extend the service life. Pipeline materials are two types of stainless steel and engineering plastics.
Components and piping are fixed to the rack, making it a complete device.
Booster pump is the membrane separation device power components, the power consumption of the pump in exchange for the separation of liquid components, the pump model selection is very important, must match the equipment specifications. Pump head generally have to reach 50 meters, flow depending on the equipment membrane area. The type of pump should be determined according to the characteristics of the processing liquid.
Containers are used to store the liquid or liquid to be processed, usually by the user with equipment, its capacity and the number should be determined according to process requirements. For large membrane separators, separate purge vessels and connection lines should be provided. A cooling system shall also be provided in the vessel.
Control box contains power switches, pressure gauges, thermometers and other components. Is essential for running the operation of the components. Flowmeter mounted on the rack, is also a necessary component.
Protect the filter. In order to protect the membrane components can be long-term safe operation, in the booster pump outlet pipe installed near a protective filter to remove small debris particles. Is also very necessary. The filter is equipped with more than 150 mesh filter. The protector is the device that is optional.
