Detailed Description
Sintered porous Titanium filter elements
一、Introduction: 
Sintered porous Titanium filter elements is made of titanium powder as raw material, through the process of powder classification, molding, sintering, mechanical welding process and so on.
The porosity and the filtration precision can be adjusted in a wide range, it is widely used in the pharmaceutical industry, water treatment industry, food industry, biological engineering, chemical industry, petrochemical industry, metallurgy industry and gas purification, it is a new type of filter material.
 
二、Filtration principal: 
Sintered porous Titanium filter is made with the method of powder metallurgy, A large random or directional pores were distributed in interior. Internal pores may be designed to various shapes such as foamed type and honeycomb type, and so on. The filtration mechanism is typical deep filtration.
  
三、Main properties: 
1、The pore size is uniform, the pore shape is stable, and the separation efficiency is high。  
2、High porosity, small filtration resistance, high penetration efficiency。  
3、High temperature resistance, can be used under 300℃  
4、Good chemical stability, acid and alkali corrosion resistance (PH2-12), oxidation resistance。  
5、No particles fall off, no secondary pollution , meet the requirements of food hygiene and pharmaceutical GMP  
6、Good mechanical properties, low differential pressure, large flow, pressure filtration and pumping filtration workable, simple operation。  
7、Strong ability of anti microbial, and no interaction with microorganisms。   
8、Online regeneration, easy cleaning, long service life(Generally several times the membrane filter) 
9、the length without welding can up to 1000mm 
10、Non-magnetic and non-toxic, and has a good compatibility with human tissue and blood, is widely used in the pharmaceutical industry, food industry and water treatment industry
六、precautions for use:  
1、Must be used vertically, before the installation of the shell, you must check whether the gasket is in place or not, misplacement and leakage is strictly prohibited
2、For the threaded interface, avoid excessive force when installing nut
3、After the shell is installed, it should be cleaned for 15 minutes to 20 minutes.
4、The normal working pressure should be controlled at 0.15 ~ 0.25Mpa. If the pressure increases, it will greatly increase the difficulty of back flushing,, which will effect of back flushing. There must be 3 ~ 5 minutes of low pressure starting time before the normal use, that is, the pressure must gradually increase to 0.15 ~ 0.25Mpa, transient application of voltage is strictly prohibited
5、Suggest back flushing every 8hous, time,10 ~ 20 minutes for each time, pressure should be gradually pressurized to 0.25 ~ 0.3Mpa.
6、when the blockage is serious and the effect of back flushing is not obvious, ultrasonic cleaning or chemical cleaning (acid pickling and alkali washing) should be adopted
 
七、Cleaning method:  
According to the pollution situation and physical and chemical properties of titanium,,the physical and chemical methods can be used for the regeneration and cleaning。The physical methods includes backflushing by clean liquid, blowback by clean gas and ultrasonic cleaning. Chemical methods are mainly used dilute acid, dilute alkali, oxidant, surfactants, enzymes and other cleaning agents. The above methods can also be used interchangeably.
According to common applications, cleaning methods are as follows: 
1、In the field of pharmaceutical and chemical industry, it is necessary to adopt the method of reverse blowing, backwashing and ultrasonic cleaning together frequently  to achieve the best cleaning effect
2、In water industry, because the surface of the filter is mostly non water soluble salts and oxides, generally immersed in 5% nitric acid is enough, ultrasonic cleaning is not required
3、In stock solution filtration, the following methods are used for cleaning according the chemical properties of pollutants: 
(1)Alkali washing:Soak the filters in analytically pure 3-5 % sodium hydroxide for 30 to 60 minutes at temperature of 40 ℃, if processed in ultrasonic cleaner would be better. Then washing it using deionized water or water for injection,and measuring conductivity. At last, blow-dry it with clean air with pressure large than 0.4Mpa. 
(2)Pickling:Soak the filters in the 5% nitric acid solution for more than 8hours at temperature of 40℃, if processed in ultrasonic cleaner would be better. Then washing it using deionized water or water for injection,and measuring conductivity. At last, blow-dry it with clean air with pressure large than 0.4Mpa. 
 
(3)Elution with surfactant for organic pollutants,  elution with enzyme detergent for cell debris contamination, elution with high-concentration citric acid in food and drink industry. 
 
These methods can be used alone, can also be used interchangeably with each other. If possible, using ultrasonic cleaner together would be better.
Attention:filters should  be cleaned often online by backwashing and back flushing.
 
八:Application
