PROCESS FLOW · WHAT EACH STAGE ACTUALLY REMOVES
The treatment train
Pretreatment protects the membrane. Only the membrane removes dissolved salts. The TDS reading beside each stage shows where the real drop happens — shown here on 800 ppm well water.
» Output TDS scales with your feed water — 97% rejection applies to your water, not ours.
» Softener and UV stages are specified per water report. » An online conductivity meter reads permeate quality continuously. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

BEFORE YOU ORDER
Send us three numbers
An RO skid is configured against your feed water, not picked off a shelf. These three figures let our engineers confirm membrane count, pump head and recovery rate before anything is built.
No water report? Send a sample result from any local laboratory, or tell us the region and the application — we have configured systems for buyers in over 100 countries and can start from comparable water.

PACKING & DELIVERY
What arrives
Export packing
Every unit is wrapped in protective plastic film, corner-protected and crated in a fumigation-free export wooden case. Vessels are strapped to the skid so nothing shifts in transit.
Shipping volume is 2.1 CBM at 350 kg gross — comfortably inside LCL sea freight, with air freight possible for urgent orders. We ship EXW, FOB or CIF and can consolidate tanks, filling lines or spare membranes into the same container.
OEM and ODM accepted: your brand plate, panel layout, colour, vessel material and stage configuration.

QUESTIONS BUYERS ASK FIRST
FAQ
Q. Will 500 L/H be enough for my plant?
Size against your peak draw, not your average. Running 24 hours gives 12 m³ per day; an eight-hour shift gives 4 m³. If your daily demand is close to the limit, add a larger pure water tank rather than a larger skid — storage is far cheaper than capacity.
Q. What TDS can the feed water be?
The standard configuration is built for brackish feed under 2,000 ppm. Between 2,000 and 10,000 ppm we change membrane type and pump head. Seawater at roughly 35,000 ppm needs a different system entirely — send us your figure and we will quote the right one.
Q. How often do membranes and cartridges need changing?
The 5 µm cartridge is a consumable, typically every one to three months depending on feed turbidity. RO membranes last two to three years on properly pretreated water. Rising permeate conductivity or falling flow tells you when cleaning is due.
Q. Does it produce drinking water directly?
RO permeate meets drinking water standards for dissolved solids, and the UV stage handles disinfection. For bottling you would normally add remineralisation or ozone depending on local regulations — we can include either stage.
Q. Are spare parts available after installation?
Yes. Membranes, cartridges, pumps and control components are stocked and shipped worldwide. Installation and commissioning support is provided by video call, with drawings and a written checklist supplied with the machine.
Q. What is the lead time?
Standard configurations ship in 7 to 15 working days after order confirmation. Customised stage layouts, non-standard voltage or OEM branding typically add one to two weeks.

A 6-stage commercial reverse osmosis (RO) water purification plant rated for 500 liters per hour (LPH) of purified output; sized for continuous, higher-volume use in factories, offices, restaurants, bottled-water operations, and other commercial or institutional settings where a household RO unit isn't enough. The 6-stage layout is the standard commercial configuration: sediment and carbon pre-filtration ahead of the RO membrane stage, with a post-carbon polishing stage after it. No price or physical specifications (weight, dimensions, pump/electrical rating) are set yet; none were provided, and this is a large enough system that guessing at them isn't a reasonable substitute for the real sourced numbers. Fill those in from the actual unit before publishing.
