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 is the minimum order quantity (MOQ)?

The minimum order quantity varies by model. For household membranes, the minimum is 100 units (two boxes). For industrial membranes, the minimum is five pieces. OEM orders may have different requirements.

Q:What are the advantages of your 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 the warranty or guarantee for quality problems?

We maintain zero customer complaints on our 3G and 4G products. If a quality problem is verified through our reasonable process, we guarantee replacement and cover the freight costs.

Q:What is the operating pressure for the 8040 ULP membrane?

The 8040 ULP (Ultra Low Pressure) series operates at 150psi, which is approximately 2/3 of the pressure required by conventional low-pressure membranes, while maintaining high permeate flow and rejection rates.
