SINOMEMB® industry energy saving SNLE series RO membrane elements
Energy Saving series SNLE element is suitable for desalination
treatment of surface water, groundwater and some low pollution
water sources with salt content below 1000ppm.It is mainly suitable
for municipal landscape, water supply and drainage, agricultural
irrigation, municipal drinking water, small low-pollution medium
water treatment,pure water of healthcare industry and ultra-pure
water, commercial pure water machine, integrated water purifier and
so on. There the advantages of ultra-low operating pressure,
ultra-high water yield flux, ultra-high desalination rate,
ultra-low operating energy consumption and so on.
Extremely Low Pressure Elements
Brief Introduction
XLP series (extremely low pressure) aromatic polyamide RO element is developed by VONTRON for treatment of surface water and
underground water. Its operation pressure is about 1/2 of low
pressure membrane, and the rejection rate can reach 98%. Thus it
can reduce the investment cost of related pumps, pipelines,
containers and other equipments and the operation cost of reverse
osmosis system, improve economic benefits.
Scope of Application
XLP series RO element normally suitable for treatment of surface
water, underground water and municipal water with TDS is less than
1000 ppm, It is especially suitable for the second pass of two-pass
RO system. It is mainly applied in bottle water, drinking water,
boiler replenishment water, food processing and pharmaceutical
manufacturing industries and other fields.

FAQs on Reverse Osmosis RO Membrane OEM Manufacturing
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.
Q1: What type of RO membrane is available in your company?
A1: In general, Hikins has Domestic RO membranes and Industrial RO
membranes. For Domestic RO membranes, Hikins has Municipal Tap
water RO membranes, Rural Area Under Ground water RO membranes,
High-flow Low-pressure RO membranes, and Brackish water RO
membranes. For Industrial RO membranes, Hikins has Low-Pressure
energy-saving RO membranes, BW Brackish water desalination RO
membranes, FR Fouling Resistant RO membranes, as well as XLE
Extreme Low-Pressure RO membranes, and High Salinity Brackish Water
Desalination RO membranes.
Q2: What is the Salt Rejection Ratio?
A2: The Salt rejection describes the quality of salt removed from
the Reverse Osmosis feed water stream as a percentage. It's one of
the key elements of the RO membrane quality, however, other
essential elements such as RO membrane performance durability,
stability, application scope in different regions, and permeate
flow output at the same pressure will all be the important factors
to judge the quality of the membrane.
Q3: Is the Salt ratio of the RO membrane the higher the better?
A3: This will depend on the feed water quality, if the feed water
quality is good, even a 90% salt rejection membrane will be
workable, if the feed water is of bad quality and with a brackish
water environment, a higher salt rejection above 95% is an ideal
choice. Any membrane that meets the local drinking water standard
will be good.
Q4: Is there are any other elements we need to take into
consideration when selecting the RO membrane?
A4: Yes, the pre-treatment filter cartridge and the pre-treatment
system will affect the RO membrane performance as well, please
select good quality filters and pre-treatment system.
Q5: Why there are white foam-like water being in the treated water
at the initial usage?
A5: To preserve the RO membrane for a long shelf-life, and prevent
the membrane from being oxidized, a water-soluble protection
material is coated on the surface of the membrane, which will be
rejected in both the rejected water and treated water, for initial
use, both rejected water and treated water should be rejected and
the RO membrane should be thoroughly cleaned. The treated water at
initial use shall not be injected into the water storage tank.
