Product Q&A

Q:Is your company a manufacturer or trading company?

We are a manufacturer with our own factory and cooperation with other factories using our technology. Haiana has an 18-year background in the reverse osmosis membrane industry with independent R&D personnel and engineering, mastering core technology of high salt water purification.

Q:What are the advantages of your company and products?

Our technical advantage lies in high desalination technology with a unique polyamide coating process. Household membranes can handle 3,000-6,000 ppm water quality, and seawater membranes can handle 30,000-40,000 ppm, offering significant cost advantages.

Q:What is your guarantee for quality problems?

We maintain zero customer complaints on 3G and 4G products. If a quality problem occurs, we guarantee replacement and are responsible for freight according to a reasonable quality problem verification process.

Q:What is your MOQ?

Minimum order quantity varies by model. The minimum for household membrane is 100 (two boxes), and for industrial membrane is five pieces. OEM orders may have different requirements.

Q:What is the operating pressure for ULP membranes?

The ULP series membrane operates at 2/3 of the pressure required by conventional low pressure membranes while maintaining high permeate flow and rejection rates.
