Frequently Asked Questions
Everything buyers ask before the first quote — answered by our engineering team.
How much does an industrial RO system cost?
There is no fixed price — every system is sized to your feed water, capacity and outlet standard. Send us your water report and required output; we return a process design, configuration and budget range within 24 hours. Budget is driven mainly by capacity, membrane count, materials (SS304 vs SS316L) and instrument brand.
What size RO system do I need?
Tell us your required permeate flow (t/h or L/h) and daily operating hours. We size from there, then check feed TDS, temperature and recovery against the membrane design limits.
How long will the system last?
Designed for 10+ years of service life. Membranes are consumables — typical replacement every 2–3 years depending on feed water and pre-treatment.
What certifications do you have?
ISO 9001, ISO 14001 and ISO 45001, with CE marking. Full FAT report, O&M manual and certificate pack ship with every system.
Are you a manufacturer or a trading company?
We are the source factory — Shenzhen Qiukanghong Technology Co., Ltd., established 2012, with a 2,000+ m² production base across two sites and 30+ technical engineers. Factory visits are welcome.
What do you need from me to quote?
Ideally a feed-water analysis (TDS / conductivity / hardness / iron), required output flow and quality, and power supply. No report yet? Tell us the source (municipal / well / seawater) and we start from a preliminary design.
