FAQ

 
 

Q: Who is the largest RO membrane supplier?

A: Proshare Innovation Suzhou focuses on the realization of the third generation of Nano-composite thin film type high-end reverse osmosis and nanofiltration membrane TFN R & D and production, in the past 10 years has achieved rapid development, alternative to imported membrane products.

Q: Are all RO membranes the same?

A: All RO membranes operate on the same principle of filtering water through a semi-permeable membrane, but still, there are significant differences in their performance, durability, and efficiency. Rejection Rates: Some RO membranes are designed to have higher rejection rates for specific contaminants.

Q: How often should I flush my RO membrane?

A: At a minimum, the RO membrane should be flushed at the end of each work day, but it's better to do it after every use. Without flushing, the RO membrane can also become moldy, which will create additional blockages.

Q: What are the requirements for the RO membrane?

A: RO brackish membranes are typically used with brackish feedwaters containing a relatively low (TDS) compared to seawater. They require a low amount of pressure (125 – 250 psi) while maintaining a high salt rejection (>95 – 99% depending on certain conditions) and high system recoveries, ≥75%.

Q: What material is used for the RO membrane?

A: RO membranes are typically either cellulose acetate or polysulfone coated with aromatic polyamides3. NF membranes are made from cellulose acetate blends or polyamide composites like the RO membranes, or they could be modified forms of UF membranes such as sulfonated polysulfone10.

Q: What is the chemical structure of RO membrane?

A: Reverse osmosis (RO) membranes are commonly thin film composite (TFC) membranes consisting in a polyamide (PA) active layer (∼50–250 nm thickness), supported by an asymmetric polysulphone support (∼50 μm thickness) and a non-woven polyester fabric backing (∼300 μm thickness) (Petersen, 1993).
