What is the difference between PP and PE filters elements?

Water treatment is done with both PP and PE filters elements. Both filters elements are white. It is hard to tell which one is PP filter element or which is PE filter element if the specifications are identical. Is it possible to quickly distinguish them? PP filter element uses melt-blown process. PE filter element uses sintering. The PE filter element is more hard than the PP filter element in terms of hardness. It can be pressed by hand. Let me show it to you. They have their own differences.

The following features are available for the PP filter element.


A polypropylene PP filter elements is a tubular filter made from non-toxic, odorless, polypropylene particles by heating, melting spinning, traction and forming. If the raw material consists primarily of polypropylene. This is also known as PP melt blown filter elements. It can be used for water purification in large quantities. It is also suitable for the filtration and treatment of strong acids, strong alkalis, and organic solvents. It has a high dirt holding capacity, a long service life, and is very affordable.


(1) The filter element's pore size is large and uniform. This results in high filtration efficiency. Particles can bridge the pores of filter elements, so particles that are smaller than the pores may also block them. The filtration efficiency is over 98%.


(2) It is clean and free from any pollution.


(3) It resists corrosion by organic solvents and acids.


(4) High strength. The filter element will not crack if the pressure difference between the outlet and inlet is less than 0.4MPA. It can be lined with a plastic bracket or an immortal steel frame if the pressure is too high.


(5) It is inexpensive and used mainly for first-stage filtration.


The following features are available for the PE filter element.


1. High flow rate: A high level of porosity (60%) allows for a higher fluid flow rate per area.


2. Smooth outer surface: Impurities don't stick to a smooth outer surface so backwashing can be easy and thorough.


3. Strong anti-fouling capability: The filtering precision of small outside particles and large inside filters out impurities. The sludge can also be pressed to 70% water content.


4. High cost performance: This filter element is highly efficient and affordable. It can be used for water treatment, reclaimed drinking water reuse, chemical product filtering, and other conditions that require large flows.


5. Resistance to strong acid corrosion and alkali corrosion, resistance to organic solvent vapor dissolution


6. Its service life is extended by its strength and wear resistance.


7. It is difficult for impurities to stick to the external light surface.


8. It is simple to reuse the recoil backflush


9. The filter element has a high degree of toughness and is difficult to break.


10. There is no threshing phenomenon.


11. High resistance to pressure

Chinese Mask Producers Meet Global Demand

As the Covid-19 pandemic continues to spread across the globe, thousands of Chinese factories have switched production to a new and highly profitable market - disposable face mask for export. Face masks In early February, during the height of China's outbreak, a company in the country's northeast designed and created a new face mask in eleven days. The company's factory, which has five production lines, started producing the masks which were in high demand as the numbers of those with the infection surged. As cases in China have now dropped, and the export of the much in demand face masks to Italy, where the death toll has now overtaken that of China. In the first two months of 2020, nearly 9,000 new face mask manufacturer in China began producing masks in a race to fill the gap in demand. As the virus epicentre of Hubei province was placed on lockdown and the numbers of infected people began falling in China, new outbreaks emerged across the world. There are now over 500...

Did you know ECO BOOM bamboo diapers are biodegraded 2.5 times faster than leaves?

1 year, 365 days, is the time for tree leaves to be fully biodegradable. While, Eco Boom bamboo diapers only need 147 days to achieve 70.1% biodegradability under SGS test.  We've thrown away 6.3 billion tonnes of plastic since mass production began in the 1950s but only 600 million tonnes have been recycled. The remaining 4.9 billion tonnes have been sent to landfill or left in the natural environment, wreaking havoc on wildlife and marine life. Plastic is both a blessing and a curse; although plastic revolutionized the way we live, the impact it has today is detrimental. In an attempt to resolve this issue, bio-plastics have emerged as a possible solution. How does plastic degradation effect the environment?  Although all plastic is biodegradable, this process takes many, many years. Traditional plastic like PET (polyethylene terephthalate) can't readily decompose or biodegrade. Why? Both processes are dependent on bacteria that consume and breakdown waste into simple matter...
