The RO-4000 is a skid-mounted industrial reverse osmosis system rated at 4 tonnes per hour permeate, with a salt rejection rate of 99% or higher. It is the core workhorse of our export range, engineered for continuous 24/7 duty in pharmaceutical, food & beverage, boiler feed and brackish/seawater pre-treatment projects.
As a source factory established in Shenzhen in 2012 (1,500+ delivered projects, ISO 9001 / 14001 / 45001 certified), we build every RO skid to the client’s feed-water report rather than to a fixed catalogue spec. Capacity platforms span 0.25–100 t/h.
Key specifications
- Capacity: 4 t/h permeate (customisable)
- Salt rejection: 99%+ (TDS / conductivity)
- Recovery: 50–75% (brackish), 30–45% (seawater with energy-recovery option)
- Configuration: single-pass standard, double-pass optional
- Membranes: 8040 elements, FilmTec / Toray / Vontron
- Operating pressure: 1.0–1.6 MPa (brackish) / 5.5–6.5 MPa (SWRO)
- Control: PLC + HMI, automatic flush, CIP, remote monitoring ready
- Frame: SS304 / SS316L skid, containerised option available
Typical applications
- Boiler feed-water make-up
- Pharmaceutical purified-water pre-treatment
- Food & beverage process water
- Brackish / seawater desalination front-end (SWRO)
- Electronics and laboratory pure-water front-end
