What Is the Underground River Bottled Water RO System?


King Machine’s Complete Underground River Bottled Water RO Treatment System is a specialized solution for converting underground river water (often high in minerals, sediments, or dissolved salts) into safe, drinkable bottled water. It uses reverse osmosis (RO) as the core technology, combined with multi-stage pretreatment and post-sterilization, to meet national and international drinking water standards (e.g., WHO guidelines). This system is ideal for bottled water factories, small-scale water plants, and communities relying on underground river water sources.


Step-by-Step Working Process of RO Treatment


Pre-Treatment: Remove Impurities & Hardness

First Stage: Silica Sand Filtration: Uses multi-medium quartz sand to remove sediments, rust, colloid materials, and suspended solids larger than 20μm. This reduces water turbidity and protects subsequent filters.

Second Stage: Activated Carbon Filtration: Eliminates pigments, odors, residual chlorine, and organic pollutants (e.g., pesticides). It also reduces the “earthy” taste common in underground river water.

Third Stage: Sodium Ion Exchange: Removes calcium and magnesium ions to soften water, preventing scale buildup on RO membranes (a major cause of membrane damage and reduced efficiency).

Fourth Stage: Precision Filtration: A micron filter catches fine particles and colloids that escape pre-treatment, ensuring the water meets RO membrane inlet requirements.


RO Membrane Filtration: Deep Purification

• The system uses imported Hydranautics (USA) RO membranes—one of the most reliable brands in the industry. These membranes remove over 97% of dissolved salts, 99% of colloids, bacteria, viruses, and most organic compounds.

• A high-pressure multi-level centrifugal pump (imported core components) provides the necessary pressure for reverse osmosis, with a pressure control valve to maintain stable operation.


Post-Treatment: Sterilization & Storage

UV Sterilization: Uses ultraviolet light to kill any remaining bacteria that may pass through the RO membrane, ensuring the water is microbiologically safe.

Ozone Sterilization: An ozone generator produces ozone, which is mixed with water in an ozone mixing tower (made of SUS 316 stainless steel) to provide secondary sterilization and extend the water’s shelf life.

Water Tank: A food-grade SUS 304 tank stores the purified water, with a level sensor to control water flow and prevent overflow.


Core Components Ensuring Purification Quality


Silica Sand Filter: High-quality quartz sand with uniform particle size, ensuring efficient impurity removal.

Activated Carbon Filter: Coconut shell activated carbon (higher adsorption capacity than coal-based carbon) for better odor and chlorine removal.

RO Membrane: 4040 or 8040 Hydranautics membranes, selected based on the system’s capacity needs.

UV Lamp: A long-life UV lamp (5,000+ hours) with a failure alarm to ensure continuous sterilization.

Control Panel: A PLC-based control system automates the entire process, with pressure gauges, flow meters, and electrical indicators for real-time monitoring.

Unique Advantages of Our RO System


High Efficiency & Low Cost: A 50–75% water recovery rate reduces wastewater, and the system’s low energy consumption (compared to traditional distillation) lowers operational costs.

Durable Materials: The main body is made of SUS 304 stainless steel, and the ozone mixing tower uses SUS 316—both materials are corrosion-resistant and meet food safety standards.

Easy Operation & Maintenance: The automatic control system requires minimal manual intervention, and King Machine provides a 12-month warranty plus lifelong technical support for components like RO membranes and pumps.

Certifications: Complies with ISO 9001 and CE standards, ensuring it can be imported and used in global markets without regulatory issues.
