Product Q&A
Q:Is your company a manufacturer or trading company?
A:
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?
A:
Our technical advantage lies in high desalination technology. The polyamide coating process differs from counterparts, allowing household membranes to handle 3,000-6,000 ppm water quality and seawater membranes to handle 30,000-40,000 ppm, with obvious cost advantages.
Q:What is your MOQ?
A:
Minimum order quantity varies by model. For household membranes, the minimum is 100 (two boxes). For industrial membranes, the minimum is five pieces. OEM orders have different requirements.
Q:What is your warranty policy for quality problems?
A:
We maintain zero customer complaints on 3G and 4G products. If a quality problem occurs, we guarantee replacement and are responsible for freight costs according to a reasonable quality problem verification process.
Q:What is the operating pressure for the ULP series?
A:
The ULP (Ultra low pressure) series operates at 2/3 of the pressure required by conventional low-pressure membranes, while achieving similar permeate flow and rejection rates.
