Introduction
As a leading manufacturer in China, we take pride in presenting our latest product – Medium-RO Series Reverse Osmosis Water System. In today's world, where water scarcity and pollution have become significant problems, having access to clean and pure drinking water is crucial. It is the need of the hour to understand the importance of water and take adequate measures to conserve it. Our Medium-RO Series Reverse Osmosis Water System is designed to offer fresh and pure water to people, irrespective of their location.
What is Reverse Osmosis?
Reverse Osmosis is a water purification process that removes contaminants from water by using a semi-permeable membrane, activated carbon filters, and sediment filters. In this process, high-pressure pumps are used to force the water through a membrane that traps impurities and contaminants, leaving behind clean and pure water.
Features of Medium-RO Series Reverse Osmosis Water System
1. Advanced Filtration Technology:
Our Medium-RO Series Reverse Osmosis Water System uses advanced filtration technology to purify the water completely. The system includes a pre-sediment filter, activated carbon filter, a reverse osmosis membrane, and a post carbon filter. These filters work together to remove most impurities, including bacteria, viruses, chemicals, and minerals, to give you fresh and clean water.
2. High-Quality Components:
We use only high-quality components to manufacture our Medium-RO Series Reverse Osmosis Water System. All the parts used in the system are tested and certified, ensuring that they meet the international quality standards.

With microcomputer controlling system in LED display, stainless steel shell, built-in 2 set pressure tanks, single stage RO system, 1 pump, portable TDS test pen and on-line conductivity monitor, Medium-RO series reverse osmosis water system is economic choice of RO water’s mass usage for general glassware washing.
With tap water inlet, its output ranges from 45 to 125 liters/hour. It can produce single stage RO water. The single stage RO water’s ion rejection rate is more than 97% (new RO membrane), organic rejection rate>99% (when mw>200 Dalton), particles and bacteria rejection rate>99%. It is suitable for glassware washing, feed of ultrapure water system, autoclave sterilizer, constant temperature and humidity chamber, salt spray test chamber, dampening machine and etc.
