Name: China B RO Membrane Manufacturers Suppliers Factory - Customized B RO Membrane Wholesale - Puri-guard Water Treatment
Brand: Puri-guard
SKU: 271207737

Product Description

B grade RO membrane is not our regular products, only to meet our certain customers' special requirements, normally with lower rejection but right or higher flow. For big population countries, usually have such requests. In order to serve better and meet special customers 'requirement, we provide these products to Middle East, Africa, India etc.

Product advantages

what is B grade

Under the same production equipment and technical conditions, this type of membrane is manufactured with a less stringent membrane sheet reaction process or with minor raw material variations to reduce cost.

As a result, the salt rejection rate is slightly lower, but it offers key advantages:

Higher water flow (flux)

Lower operating pressure required to achieve the same flow rate

Better cost-performance balance for target applications

This higher permeability allows the membrane to meet water production requirements more efficiently, especially in systems where extreme rejection is not critical.

Lower rejection but can accpetable in using

higher flow support

lower cost

higher flow

lower pressure can reach the same flow , energy-saving

Rejection

Domestic is around 93-95% , indsutrial is 95%-98 around

models ranges

Models all is support , ncludes all domestic and industrials

size and applications

stanadard size and applications same , only rejection requirement lower

3. Single membrane element production flow may vary ±20%.

Operating limit

Diaphragm type	Polyamide Composite Membrane
Maximum operating temperature	113℉ (45℃)
Maximum operating pressure	150 psi(10 bar)
pH range, continuous operation	3-10 ^a
Maximum Influent SDI	5
Free chlorine tolerance	<0.1 ppm ^b

a. When pH > 10, the maximum allowable temperature for continuous operation is 95℉ (35℃).

b. Under certain conditions, the presence of free chlorine and other oxidants will lead to premature failure of membranes. Therefore, it is recommended that the membrane be pretreated to remove residual free chlorine before water comes into contact with membranes.
