Physicochemical index

Ultrafiltration is a pressure-driven purification process in which water and low molecular weight substances permeate a membrane while particles, colloids, and macromolecules are filt.The primary removal mechanism is size exclusion. A properly designed UF cartridge allows efficient rising of ionic redidue from the cleaning and rapidly returns to optimal resistivity and organic purity.

Shenzhen CKK Co.,LTD. was founded in 2019, which is a modern enterprise and dealing in exploding, designing, producing and servicing. We are specialized in producing RO Membrane, UF Membrane, UV Sterilizer, RO Syetem, RO Fittings and all kinds of water filter accessories. 

Locating in Shenzhen City, we have a 30000 m² modern industrial park with advanced equipment, mature producing technology, thorough servicing system and high quality but competitive price products, the most honorable is that we have great approval from our customers who come from different countries and regions in Middle East, Southern Asia, Africa, East Asia, Americas, Euro,etc.

1. There is too much silt and rust in the water, can it be used? Whether prefilter is needed.
Yes, but the frequency of cleaning is relatively frequent. The essence of ultra filtration is physical filtration. It is suggested to slightly precipitate and then filter. Prefilter are not required.

 3.Can you provide free UF membrane samples?
Yes we can provide a free sample to testing, buyer should bear all the shipping costs.

4.Is there only this type of UF membrane?
No , we have PVDF UF membrane series.

5.How could I know it's time to change the filter?
When water flow slow down much, or even can not sip water through product, then it is time to change the filter.

6.How about goods delivery time ?
Sample order : within one week ; Large order : 15~25 days.
