Reverse Osmosis Pure Water Treatment Equipment
Reverse osmosis water treatment equipment from JNDTECH in the JND RO1000 configuration, 200 to 8,000 litres per hour with a desalination rate of 98 percent or higher. Three pretreatment stages protect a TFC compound membrane, and the unit runs on one stage or two stage RO.

| RO Stage | One Stage/Two Stage |
Product Description
Reverse osmosis water treatment equipment from JNDTECH covers both the pretreatment train and the membrane stage. The JND RO1000 removes dissolved salts, organic matter, bacteria and viruses from raw water.
Standard output runs 200 to 8,000 litres per hour at a desalination rate of 98 percent or higher.
Food and beverage plants, pharmaceutical workshops, chemical processors and chrome plating shops run it as the first stage of a production line.
How the Reverse Osmosis Water Treatment Equipment Works
A high pressure pump forces raw water through a semi-permeable TFC compound membrane, the core of this reverse osmosis water treatment equipment. Water molecules pass through, dissolved salts do not.
The stream splits into permeate and concentrate. Permeate is the product water, and concentrate carries rejected salts and bacteria out of the system.
Cross flow keeps the membrane surface swept, so the unit runs continuously between cleaning cycles. Plants needing water purer than reverse osmosis can reach add an EDI water treatment stage after the membrane.
Pre-Treatment Stages That Protect the RO Membrane
Raw water passes three stages before it reaches the membrane. A multi media filter of quartz sand and grain activated carbon traps suspended particles and colloids. An activated carbon filter removes chlorine, and a PP sediment filter catches the rest.
Chlorine attacks TFC compound membranes, so the activated carbon filter is what keeps the membrane alive for its full rated life.
Electrical protection stops the unit on open circuit, short circuit and creepage. A level switch follows the raw water tank, and the membrane auto-washes on a set cycle with manual override.

One Stage vs Two Stage RO
One stage suits soft feed water that reaches target conductivity in a single pass. Two stage passes the permeate through a second membrane bank for harder water.
| Item | One stage | Two stage |
| Membrane banks | One bank, raw water passes once | Two banks in series, permeate feeds the second |
| Suits feed water where | Dissolved salts are low enough for a single pass | Dissolved salts exceed what a single pass can bring to target |
| Desalination rate | 98 percent or higher | 98 percent or higher per bank |
| Skid length | Shorter | Longer, with more membrane housings |
Both configurations share the same SS304 frame and TFC compound membrane. Two stage costs more and takes more floor space, so we quote one stage first and move up only when a water analysis calls for it.
Applications and Output Range
Custom builds of this reverse osmosis water treatment equipment reach 100,000 litres per hour for large bottling and municipal projects, against the 8,000 litre standard.
Feed water conductivity decides the configuration more than the industry does. Mains water, well water and river water all fall inside the 1,000 microsiemens per centimetre limit. Saltier sources go to our seawater desalination equipment.
For smaller bottling shops needing a few tons per hour, the commercial RO treatment equipment covers the same treatment train on a shorter skid.
Component brands are selectable: fibreglass or stainless steel membrane housings and filter tanks. The high pressure pump comes from Grundfos and the membrane elements from Hydranautics as standard.
Why Choose JNDTECH
Shenzhen J&D Drinking Water Equipment Co., Ltd. has built beverage equipment since 2008, delivering over 9,000 machines to 450 factories across 125 countries with ISO 9001, CE and multiple patents.
Every reverse osmosis water treatment plant we ship carries a one year warranty and a 24 hour response window, plus on-site installation, commissioning and operator training.
We size the pretreatment train against your water analysis rather than a catalogue default, since two plants on the same street can need two different configurations.
Frequently Asked Questions
What feed water quality does the unit accept?
Conductivity of 1,000 microsiemens per centimetre or lower, pH between 2 and 11, temperature between 1 and 45 degrees Celsius. Water outside those limits needs different pretreatment, so we requote instead of risking the membrane.
Does the equipment run unattended?
It runs on automatic control with an auto-check conductance display showing water quality continuously. Protection circuits stop it on open circuit, short circuit and creepage, so an operator monitors rather than runs it.
One stage or two stage for bottled water?
Most bottled water plants reach the standard on one stage when the raw water is municipal or well water. Two stage is quoted when the analysis shows dissolved salts a single pass will not bring to target.
What maintenance does the RO membrane need?
The membrane auto-washes on a set cycle and can be washed manually when output quality drops. The conductance display shows that drop early, so the membrane gets cleaned before it is damaged.
