Customized reverse osmosis solution for cleaner and more reliable industrial park drinking water supply

Safe domestic drinking water is a basic requirement for any industrial park, where employees and resident staff depend on a stable daily water supply for drinking and general domestic use. When groundwater contains excessive dissolved solids, suspended particles, odor, or other contaminants, it can affect water safety, reduce user confidence, and increase the burden on facility management.

To improve domestic water quality and strengthen infrastructure support, an industrial park in Nigeria selected Zhongnuo Water Treatment to design and manufacture a 12 m3/h purified drinking water treatment system. The customized solution was developed to convert groundwater into cleaner and safer drinking water, helping the client improve water quality consistency, support daily consumption needs, and reduce operational risk from untreated source water.

As domestic water demand within the industrial park increased, the client needed a more dependable treatment solution. The key project challenges included the following:

◎ Groundwater quality was not suitable for direct drinking use

Although groundwater was available on site, it could contain dissolved solids, suspended impurities, odor, and other water quality issues that made direct domestic use unsuitable without proper treatment.

◎ The park required stable daily supply for multiple drinking points

The industrial park needed a reliable treated water output of 12 m3/h to support drinking water points across the site. Stable production and distribution were important to avoid interruptions in daily domestic water access.

◎ The system had to balance water quality and operational practicality

For domestic water projects, the treatment process must be effective while remaining practical to operate and maintain. The client required a compact and reliable configuration that could deliver cleaner water with manageable operational complexity.

◎ Water distribution reliability also mattered

Treatment alone was not enough. The client also needed a water storage and supply arrangement that could maintain stable pressure and consistent delivery to drinking points throughout the park.

Groundwater  ->  Raw Water Tank  ->  Raw Water Pump  ->  Multi-media Filter  ->  Activated Carbon Filter  ->  Security Filter  ->  High Pressure Pump  ->  RO Reverse Osmosis System  ->  Pure Water Tank  ->  Water Supply System  ->  Industrial Park Drinking Water Points

This 12 m3/h purified drinking water treatment system was designed specifically for industrial park domestic water supply applications. It integrates pretreatment, reverse osmosis purification, storage, and distribution into a practical process line for continuous drinking water production.

Pretreatment for improved feed water condition

The process begins with the Raw Water Tank and Raw Water Pump, followed by a Multi-media Filter to reduce suspended solids and an Activated Carbon Filter to address odor, color, and certain organic compounds. A Security Filter then captures fine particles before water enters the high pressure section.

RO purification for cleaner domestic drinking water

The High Pressure Pump feeds water into the RO Reverse Osmosis System, which removes a large proportion of dissolved salts and other impurities from the groundwater. This helps produce cleaner and safer water that is much more suitable for daily drinking use than untreated raw water.

Stable storage and park-wide supply

After purification, water enters the Pure Water Tank and then flows into the Water Supply System, which distributes treated water to Industrial Park Drinking Water Points throughout the site. This arrangement helps maintain stable supply and supports daily domestic water demand.

Designed for dependable daily operation

The system was configured to provide practical operation, stable output, and cleaner final water quality for daily domestic use. It is suitable for industrial parks, worker communities, and similar facilities that require a dependable centralized drinking water solution.

After installation and commissioning, the purified drinking water system successfully met the site’s domestic water requirements and improved the reliability of drinking water supply within the industrial park.

· Stable purified water output of 12 m3/h for daily domestic use.

· Improved drinking water quality for industrial park users.

· Reduced dissolved solids, odor, and suspended contaminants from groundwater.

· More reliable centralized water supply to multiple drinking points.

· Better support for daily staff welfare and facility operation.

· Lower operational risk associated with untreated groundwater use.

With the new system in operation, the client established a cleaner and more dependable drinking water infrastructure, improving both daily convenience and long-term site water management.

1. Why use RO treatment for industrial park drinking water?

RO helps remove dissolved salts and many other impurities from groundwater, producing cleaner water that is more suitable for domestic drinking use.

2. What is the role of activated carbon in this system?

The activated carbon filter helps reduce odor, color, residual organics, and certain compounds that may affect downstream performance and final water quality.

3. Why is a pure water tank needed after the RO system?

The pure water tank provides treated water storage and helps stabilize supply before the water is distributed to multiple drinking points across the industrial park.

4. Can this system be customized for larger or smaller sites?

Yes. Zhongnuo Water Treatment can customize system capacity, pretreatment configuration, RO design, and distribution layout according to water demand and source water conditions.
