With years of advanced mould manufacturing and plastic injection technology in water treatment industry, as well as a group of professional engineers and marketing team, we are engaged in developing our company into a production base of water treatment parts and RO machines.

The mambranne has its characteristics as flows:

• high rejection. they give high rejection in trearing with pestcides,by product of disinfection often seen from the tap water.
• with high stablity and optimization structure.the membrane adopts the design of wide feed net and short membrane leaves.this series of film owns the high stablity and can be cleaned.
• we supply wide scope of chioce and complete specifection. in order to meet the need of customer on water output .we can also make special dimension and specification of membrane as customer require.

1.

Notice :test conditions

1.the test is under water temperature 25°C,nacl 500mg /l, pH 7.5 and the standard recycle rate and so pressure .

2.the water output deviation of single membrane is between 15percent .of mean value .

3. the lowest desalination rate is 95.0%

Important information and notice :

1 more information about design parameters ,you can read the UK new version of manual ,design direction and other relative data , or have a consultation with technologist .if user doesn’t obey the manual offered by us ,we will take no responsibility for what happen .

2 all the membranes are tested strictly and treated with 1.0% NAHSO3 for storage (propylene glycol antifreeze is added in winter ) before shipped .we adopt vacuum packaging and the hard cardboard is used for packaging . to prevent the UK growing of microbial in short term storage and transport . the protect liquid of 1.0% NAHSO3 is promoted (confected with ro pure water )to marinate components .

3.its suggested that the first hour of pure water be drained.

4.any chemical medicament ,having a bad effect on membranes performance .is bidden to add in the period of storage ,installation and normal function .when install ,please use pure water or glycerin if lube is needed .when clean ,refer to the clean method and the chemical medicament of complex offered by us .if you use other chemical medicament ,we will not take responsibility of what happened .

5.frp (fiberglass –reinforced plastic )is adopted for 4040 and the like 040 and the limited pressure is 15psi .adhesive tape wrap is adopted for household membrane .and pyrocondensation film is added for other dimension of membrane .

6.all the membrane produced by feyian adopt the universal standards of international size .and can interconvert with all types of membrane presently .25series adopt the pressure vessel whose diameter is 2.5inches ,40 series 4.0inches and 80 series 8.0inches .
