HYDRANAUTICS reverse osmosis membrane-----Nano-filtration
Product name: HPA-FR-8040 series membrane component
HPA-FR-8040 membrane component researched by HYDRANAUTICS is a kind of compound membrane component, which is specially suitable for municipal water supply treatment, treatment of high pollution surface water, water source, all kinds of water recycle and so on. It has many features of good salt-removing, no-blocking, stable technology performance, good output quality, high output, it will show its comprehensive performances in the using process.
HPA-8040 membrane component is suitable for water source of waste water, surface water desalinization, and the salt content in water source is less than 5000ppm, which is widely used for desalinization reuse of municipal waste water, industrial water reuse, boiler of power plant and industrial waste water reuse of a small number of organic pollutants, electroplating waste water reuse and so on.

Attentions:
All the above output are the average values, the output error of single membrane components is within ±15%.
The test conditions are not the best service condition, ask technicians for more informations.
There is the pressure container in membrane component, the nominal inner diameter is 8 inches.
Before the start of RO system, the pretreatment debugging, component filling, meter calibration and other system testing and so on should be finished.
The pressure of membrane component feedwater is boosted increasingly, the pressure is boosted to the normal operation, whose time should be more than or equal to 60 seconds.
The new membrane is installed for the first time, which should be flushed more than 2 hours, RO pure water produced should be discharged.
Pay attention to avoid the water side of product producing backpressure.
All the membrane components will be tested in the factory, 1.0% sodium bisulfite (in winter, 10% propylene glycol antifreeze will be added) solution will be used in storage, we adopt vacuum package, the external package is the hard carton box.
