As a manufacturer in China, I am proud to offer the Medium-RRO Series Reverse Osmosis Water System. This innovative product is designed to provide clean, safe, and great-tasting water for both commercial and residential use.
The Medium-RRO Series Reverse Osmosis Water System is built with the highest quality materials and advanced technology to ensure superior performance and efficiency. It uses a sophisticated reverse osmosis process to remove impurities, pollutants, and contaminants from water, including bacteria, viruses, heavy metals, and other harmful substances.
This system features a multi-stage filtration process that starts with a pre-filter to remove sediment, chlorine, and other large particles from the water. It then passes through a carbon filter that absorbs any remaining impurities and improves the taste and odor of the water. The next stage is the reverse osmosis membrane, which filters out the smallest particles, such as dissolved salts and minerals, as well as any remaining contaminants that may have escaped the previous filters.
The final step in the filtration process is a post-filter that ensures the water is clean and fresh-tasting. This four-stage process ensures that the water from the Medium-RRO Series Reverse Osmosis Water System is of the highest quality, free from impurities and contaminants.
One of the key benefits of the Medium-RRO Series Reverse Osmosis Water System is its versatility. It can be installed in a variety of settings, including homes, offices, schools, hospitals, and other commercial buildings. The system is easy to install and maintain, with a simple design that requires minimal upkeep.
Another advantage of the Medium-RRO Series Reverse Osmosis Water System is its affordability. It is competitively priced compared to other similar systems on the market, making it accessible to a wide range of customers.
Merchants looking to sell the Medium-RRO Series Reverse Osmosis Water System can benefit from its excellent performance, proven reliability, and ease of installation and maintenance. The system is well-suited for businesses that want to offer high-quality water to their customers or to individuals who want to enjoy clean, safe drinking water at home.
Overall, the Medium-RRO Series Reverse Osmosis Water System is an excellent choice for anyone looking for a reliable, efficient, and affordable way to improve the quality of their drinking water. As a manufacturer, I am committed to providing the best products and services to my customers, and I am confident that the Medium-RRO Series Reverse Osmosis Water System will meet and exceed your expectations.
Medium-R series is standard double stage reverse osmosis system. With 2 stage pump, 2 stage RO membrane and buffer tank, system achieves stable water quality, little drain, and low running cost.
Compared with single stage RO system, the quality of RO water is better, and the running cost is lower for less consumables replacement. Moreover, compared with simple 2nd stage RO system (1 pump, 2 RO membrane, without buffer tank), its system design is more rational, and the RO quality is more stable. Even though with the worse source water, the 2nd stage RO water’s conductivity also can stay 1-5µs/cm.
Medium-RRO series is 2nd stage RO water system, with LCD controlling system, 3 way water quality sensor, cartridge replacing alarm, timing and quality dispensing, stainless steel shell, built-in 2 set tanks (buffer tank and pressure tank). Its output ranges from 30 to 90 liters/hour. And the 2nd stage RO water’s conductivity can stay 1-5µs/cm, suitable for glassware washing and general grade experiments.

Features and Advantages
Automatic microcomputer controlling system, LED real-time animation mode display.
Running status is showed in the LED display, such as flushing, producing water, water full, water shortage, and check service.
Power on self-test, power reset, alarm when work more than 6 hours continuously, water shortage, leakage, low and high pressure.
With 2 pumps, 2 RO membranes and buffer tank, system assures 2nd stage RO water quality´s stability from different source water, and achieves little drain and low running cost.
3 procedure of the reverse osmosis membrane´s self-flushing: power on, water shortage reset and work more than 2 hours continuously, extend the life of RO membrane.
On-line conductivity monitor, with apheliotropic LCD display, to detect the quality of reverse osmosis water.
Attached portable TDS (total dissolved solid)/conductivity test pen, with dry cell design, to detect the quality of feed water and RO water.
High-capacity and independent cartridges design, with fast inserted adapters, easy to replace, and achieve running in the lowest cost.
Built-in 15 liters airtight plastic pressure water tank and buffer tank, save more lab space, easier for installation and maintenance.
Stainless steel shell with powder painting technics, achieve elegant appearance and meeting GLP standard.
External water tanks is optional to meet different need and assure ample water-supply.
Floor type with wheels on the bottom design, convenient to move.
3 door and easy-to-replacing cartridge design, convenient to maintain system and replace cartridges.
Tube and adapter with NSF authorization and top quality, reduce TOC level and assure water´s quality.
Long life and high-capacity pretreatment (including PP fiber, and active carbon cartridge), effectively protect RO membrane.
RO module with DOW´s membrane, ensure long life, stable operation and high desalinization rate.
