Domestic 75 80gpd RO Membrane

The Domestic 75‑80 gpd RO membrane is a compact reverse‑osmosis unit designed for household and small‑scale commercial water treatment. It is offered in two series: the TW (tap water) series operates with feed water total dissolved solids (TDS) between 500 ppm and 2000 ppm, delivering a salt rejection of 98 % and a water recovery of 25 %; the BW (brackish water) series handles feed TDS from 2000 ppm to 4000 ppm, achieving 97 % salt rejection and 20 % recovery. Both series are rated for a daily production of 75 to 80 gallons of purified water. The membranes are supplied as standard 8‑inch spiral‑wound modules.

Nanovela builds the membranes with a thin‑film composite polyamide layer on a polyester support, a construction typical for modern RO products. In the industry a stable performance under high‑TDS feed water is expected to last 3‑5 years at normal pressure, and Nanovela states that their membranes exhibit longer life under such conditions. The company runs a Massive Adaptive Testing Platform that includes a 100 % vacuum integrity test and random feed‑water performance tests to verify each module before dispatch. Typical operating pressure for these membranes lies between 10 and 15 bar, and the acceptable temperature range is 5‑35 °C.

Importers usually target residential developers, boutique hotels, or small bottled‑water producers who need reliable on‑site desalination. When contacting Nanovela, request the product data sheet, confirm the minimum order quantity, packaging dimensions and any required certifications. Trade terms such as FOB Kunshan, payment by telegraphic transfer, and lead‑time estimates should be clarified before placing an order. The supplier’s harbor‑tier verification indicates a basic level of credibility, but buyers are advised to verify test reports independently.

Suzhou Nanovela Technology Co., Ltd. is located in Kunshan City, Jiangsu Province, China, at Building 10, No. 2266 Chengbei West Road, Bacheng Town. The company is listed with a harbor trust tier on the platform and currently shows a response rate of 0 % with no recorded response time, indicating that direct communication may be required to obtain timely answers. Nanovela’s address places it within the industrial zone that serves many water‑treatment equipment manufacturers in the Yangtze Delta region.

The firm describes itself as a specialist RO membrane manufacturer and highlights its two product series, TW and BW, designed for tap and brackish water applications respectively. It emphasizes the use of a Massive Adaptive Testing Platform, which performs a full vacuum integrity test on every module and additional random water tests to ensure consistent quality.
