Membrane module standard for tap water AMST-001 (7th edition) certified product (SMF-PVDF)

Achieves high flux by special membrane formation

Flux: Approximately 4 times compared to conventional

Achieves excellent washing ability by using water and air together

Achieves effective turbidity discharge by bubbling and backwashing with permeated water

Capable of removing Cryptospodium and Legionella

Since SMF-PVDF has a nominal pore size of 0.05 μm, it is possible to remove Cryptosporidium and Giardia, which are the enemies of drinking water, and Legionella, which is the enemy of hot bath facilities and cooling towers.

● Decontamination and infection control of tap water and beverage facilities

● Advanced treatment of tap water in welfare facilities
● Pretreatment of RO membrane equipment
● Aseptic seawater production (Fish processing)
* Pretreatment may be required.

Filtration process

Treated water can be obtained by allowing raw water to permeate from the outside to the inside of the hollow fiber (external pressure filtration method).

Washing process

After removing the dirt on the membrane surface by air bubbling, the treated water is reverse osmotic and the dirt in the pores is washed away together.

Standard washing method

Washing process	1. Air wash 30 seconds > 2. Backwash 40 seconds > 3. Water drainage 10 seconds
Air wash air volume	3Nm3/h（Per cassette）
Backwash flow rate	1.5 to 2 times the filtration flow rate
Washing frequency	Once every 30 minutes

Keep the number of cassettes connected within 2 rows in parallel _and 3 rows in series.
For large capacity, use [Parallel x Series = 2 rows x 3 rows = 6 cassettes] as a block unit and use as [Multiple blocks].
Cassette connection accessories are included according to the number and arrangement of cassettes.
* When ordering, please discuss the arrangement with our sales staff.
