 Q: Are you trading company or factory?

 A: We are factory.


Q: How Does Reverse Osmosis Work?

A: Reverse osmosis systems purify water by forcing pressurized water through a very fine, plastic membrane. If the raw water being treated comes from a well or another private source, disinfection and pre-filters (to remove chlorine and/or particulates/sediment) may be needed in advance of the R/O unit to remove contaminants that can foul or damage the membrane.


Q: How Do I Know What Size Unit to Buy?

A: R/O units are rated according to the amount of treated water produced per day. For example, one type of unit produces 5000 liters of treated water per day under its design conditions. In reality, conditions frequently vary. Line pressure is often lower, water will frequently be colder than 25° C and backpressure in the storage tank will likely reduce the performance of the unit. Consequently, you should examine water conditions and buy a larger rated unit than needed if any of the above problems are noted


Q: Material of the reverse osmosis system?

 A: You can choose FRP filter + U-PVC pipe, stainless steel filter + U-PVC pipe or total stainless steel.
