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(only for residential),but customer need bear delivery fee
III: Working TDS?
Our RO element can work with 500~ 5000ppm feed water with good perforance,india south water quality 3000~4000ppm
VI: What membrane flatsheet do you use?
We use DOW FILMTEC sheet to make sure RO element stable performance
When customer has tight budgets,we choose domestic sheet with better stable 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 2~3 years. Many factors determine an RO membrane's life expectancy, such as feed water quality and frequency of use
VII: Can we OEM?
At the same time, besides standard elements, Nanovela products could be customized in size and we also accept OEM orders.
VIII: How long will you send out the order?
For 50pcs industrial membrane,we can delivery within 2 week,urgent order can be discussed
