 Here you can clike the link and see the vedio for the high flow cartridge production Production Showing of high flow cartridge filter from Brother Filtration

 1) Commission stage

According our experience, normally the feed water quality would not be stable 

Normally our clients have to choose and try proper chemicals and filter media for pretreatment.

 Considering this situation, usually they will choose large size micron filter 

Like 100-micron cartridge filter for UF pretreatment.

Brother can manufacture the special UF guard filter with custom designed membrane structure which enables our client to do wash and help to reduce maintenance cost at least 50%

 Here we have one case and we designed for Sinopec (China Petroleum & Chemical Corporation)  the washable filters applied as protection purpose before UF. The customer at first used the normal high flow filter 50pcs per month and yearly 600pcs in 2019.

 Last year we updated the washable filter to them and they wash the filter again and again and finally total service life lasts 5 month and they only use 50pcs per 6 month thus 100pcs in 2020.

If the economical low quality filter is adopted, will risk shorter service life of the UF membrane, RO guard filter as well as increase the RO membrane cleaning cost etc

 The washable UF guard 100 micron filter would still need the inner core 

Cause our client will need to wash both inside and outside of the filter element under certain pressure (Filtration area 5.5m2)

 For RO guard 5 micron filter, we suggest we prduce without inner core 

This can help increase the filteration area and extend service life 

Filtration area for the RO guard filter with inner core: 5.5m2

Filtration area for the RO guard filter without inner core: 5.8-6.0m2

 Our client at first prefer the netting high flow filter, but according our experience for such netting high flow cartridge filter, the washing times may not exceed 4 times cause the netting would not strong enough to hold the after-filtered inner membrane and can not withstand many times washing

 But the rigid cage we made is outstanding and the material is high strength and high density PP which can use for many times washing

2) Maintenance stage

After a period of modification on the chemicals and filter media, the feed water quality would become stable. Our client will send us the feed water quality report like particle allocation, SDI analyses and other data like NTU etc,

Sometimes they send us the used filter sample. We will do analyses in our Lab and will see if need to adjust the filter design and produce new cartridge filter for our clients.

Here is the high flow filter we designed for the RO guard filter

Graded membrane structure before filtration and after filtration

3) Turn over stage

After 2-3 years, probably our client would have to turn over the water plant to the owner or end user. At this stage, we also can help them on the technical support if they have such request

6. Cartridge size confirmation

 Brother have replaced many times same type cartridge like from Pall, Amazon, Parker etc. and so far no complain on the cartridge dimension.
