RO Seawater Desalination Equipment FAQ

Yes. Capacity can be specified as 1T, 2T, 3T, 5T or larger according to raw water quality, target permeate output, recovery rate, membrane selection and site conditions.

Yes. Two-tank and three-tank layouts are available. Common choices include quartz sand filter, activated carbon filter and softening tank before the security filter and RO main machine.

Yes. Runxin and Fleck valves can be quoted according to buyer preference, local maintenance habit, tank size and automation requirements.

Yes. Seawater desalination systems can include seawater RO membranes, high pressure pump, 1000 PSI membrane housings, dosing system, conductivity meter, PLC controller and CIP cleaning system.

Please provide raw water type, TDS or salinity, required output, voltage, application, site space, automation requirement, preferred component brands, order quantity and destination port.

Yes. Control panel layout, labels, language, PLC or touch screen interface and operation logic can be discussed for confirmed OEM/ODM or engineering projects.

Large RO machines can be protected with wrapping, fixed inside a frame and packed in export wooden crates. Shipping marks and basic export documents can be prepared for the destination port.

Frequently Asked Questions

Selected products can be supplied or tested according to NSF/ANSI 42, 53 and 58 requirements. ISO 9001, CE, SGS and Halal-related documents are available upon request.

MOQ for standard 10" PP, CTO and GAC cartridges starts at 1,000 pcs per SKU for stock items, 3,000 pcs for OEM-printed sleeves, and 5,000 pcs for fully customized ODM moldings (private end-cap, custom O-ring, branded shrink-wrap). UF membranes and RO 75/100/400 GPD membranes typically MOQ 500 pcs. Wall-mounted dispensers MOQ 100 units. Smaller trial orders are negotiable for new distributors.

Our manufacturing center is in Yuanhua Town, Haining City, Zhejiang Province, China — approximately 90 minutes by car from Shanghai Hongqiao Airport (SHA) and Hangzhou Xiaoshan Airport (HGH). The 20,000+ m² facility houses dedicated PP melt-blown extrusion lines, sintered carbon block presses, UF/RO membrane assembly clean rooms, and dispenser SMT/assembly lines. We welcome scheduled buyer visits, third-party inspections (SGS, BV, TÜV) and OEM qualification audits.

Standard PP, CTO, GAC and T33 cartridges in stock colors ship within 7–10 days. OEM private-label cartridges with custom printing: 20–25 days from artwork approval. RO/UF membrane elements: 15–20 days. Wall-mounted and desktop dispensers: 30–45 days depending on customization. Container loading typically 1 × 20'GP (≈ 80,000 cartridges) or 1 × 40'HQ (≈ 200 dispensers). FOB Shanghai or Ningbo; CIF, CFR and DDP terms available.

Yes. We offer full-range reverse osmosis membranes: 50 GPD, 75 GPD, 100 GPD, 200 GPD, 400 GPD, 600 GPD for under-sink residential systems, plus 300 GPD, 400 GPD and 600 GPD high-rejection elements for light commercial water dispensers. Industrial 4040 and 8040 elements (BW30, SW30 equivalents) are available for water treatment plants, dialysis, semiconductor rinse and pharmaceutical applications. Salt rejection rate ≥ 96–99%.

PP melt-blown sediment filters use thermally-bonded polypropylene fibers to remove particulate contaminants (rust, sand, silt) from 0.5 to 50 microns. CTO (Chlorine, Taste & Odor) sintered carbon block filters use compressed coconut-shell or coal-based activated carbon to remove free chlorine, chloramines, VOCs, pesticides and improve taste — typical 5 µm or 10 µm. GAC granular activated carbon filters use loose carbon granules for higher contact-time chlorine adsorption and are often the second stage in 5-stage RO systems. We manufacture all three at industrial scale with full traceability.
