Q:How is SINOMEMB membrane different from others?
A:We offer value against your money, prices which are comparatively lower, performance equivalent to best membranes available and with higher longevity.
Q:Are you a manufacturer?
A.Yes,we have been in providing the professional products in wire mesh field for more than 10 years.
Q:How about the delivery time?
A:Usually within7-10days,customized order may need longer time.
I: Are you a trading company or a manufacturer?
A:We are RO membrane manufacture,have 20 years experience in water treatment filed
II: Can I get a sample? Can I place small order before bulk purchase?
A: We can provide one free sample,but customer need bear delivery fee
III: Working TDS?
Our RO element can work with 4000ppm feed water with good perforance,india south water quality 3000~4000ppm
VI: What membrane flatsheet do you use?
We do not produce RO membrane flat sheet ourselves but source RO flat sheet from Dupont, CSM and China RO membrane flat sheet producers to further ensure RO membrane performance.
V: What's the difference Dupont sheet and Domestic sheet?
Dupont is famous,and price is higher than domestic sheet Dupont sheet has more stable performance than domestic sheet
IV: What's your RO membrane element life?
Typically RO membranes have an estimated life expectancy of 1~3 years. Many factors determine an RO membrane's life expectancy, such as feed water quality and frequency of use
VII: Can we ODM&OEM?
Besides standard elements, Nanovela products could be customized in size and label(brand).
VIII: How long will you send out the order?
For 10000pcs,we can delivery within 2 week,urgent order can be discussed
